Up graded slash transmission

[orca44]

I wish to upgrade my stock plastic xmission case to metal... Any and all recomendations would be appreciated.
And may I use stock Traxxas parts in the tranny or must I use others?

Speak or forever hold your peace....

Thanks

[O.G.]

FLM!!! All the way.



Or it you're on a budget, Golden Horizon.



My FLM alu trans have worked flawlessly for several years and I use Swami wheelie bars with them.

I just got the GH alu trans but haven't installed it yet. I looks well made and solid.

[redlightrandy]

i hear good things about the integy case. durable and you can still use your stock rear bumper and all the rpm accessories for the rear like the rpm rear bumper and motor protector and wheelie bar. i plan on getting the forged integy case and will use new traxxas internals. which ever case you get, make sure you get good lock tite also. the cases that allow you to keep all your bumpers and stuff i think are best for durability.

[adonismp82]

I have Integy case on my Slash and my Rustler, and they work great, no issues. Just make sure you get the one that you can mount the bumper.

[O.G.]

Mounting the stock bumper or wheelie bar on a spankin' new alu trans case is un-american. The swami is elegant.

Thanks for the replys guys...To try and narrow it down, I would still like to still use my RPM bumper, RPM wheelie bar and A arms.
I run a Castle SV2 4 pole 5700 KV @ 2S with 18/86 gearing. Temps a little warm, just do not run packs back to back.

With that being said, I have two Slashes set up the same except gearing and shocks, so which ever unit I chose, it will most likely be times 2, is price a concern? Yes of course... But I am lazy and do not care to do things over and over. I would like it to last and not require modification if at all possible..

So to narrow my choice.... Which of the above 3 units?

[turok]

i have a GH and 2 integy the GH seems to be the best out of the 3 and out of the 2 integy i have the one without the wheelie bar mount seems to be better built.

[kwitty]

Keep in mind that Proline is getting ready to release a Racing Transmission for the 2WD Slash with upgraded slipper and sealed diff unit very soon! Should be a pretty trick setup and allowable tuning too.

[orca44]

I went to Proline's web site and did not see anything on it about a slash etc transmission. Do you know where I may view the new product?

My LHS has an Integy one in stock but it is blue, for $44 but I would prefer bare aluminum.

[turok]

giant squid has the info.

[Kitteh298]

I have a venom, It doesnt have a wall around the motor, I don't believe that ones without walls are good if you are bashing with other people or may get hit on your rear very much. I broke off my traxxas wheelie bar, the aluminum snapped right off.

I needed/wanted one without walls because of a thread I will be posting shortly.

[orca44]

Is the new Pro-Line Performance Transmission a plastic housing. If so how will this assist in cooling? Their new xmission looks very nice and might also be a good choice .... Any can't waits out there?

turok I searched giant squid and just found squid ... Finally went to "Big Squid RC" and found it....

[kwitty]

Proline trans has an integrated aluminum motor mounting plate and less material over top of the motor which will allow better air circulation. Trans will be removable from toe plate so you don't have to remove rear arms and linkages to service or to change fluid weights in the sealed differentialt that is also offers.
There have been two YouTube videos launched by Proline showing features and benefits so far..........
Yes, I'm gonna have to have one to try out!

[Old Ezra]

Full-Alloy trans-cases are a waste of money. No ,they do not make better heat-sinks....if you need it for a H/S you're geared wrong.....The rear-bias is heavy enough without adding more weight...Use the stock-plastic case, shim it correctly and you have a bullet-proof tranny.

Seriously? They don't act as a heatsink? Where'd you get that information? They do act like a heatsink and they allow you to gear up without overheating. I run 31/76 in my Slash and my temps never go above 160-170. Sure, if you shim it right it will work better, but saying they are a waste of money is crazy stupid. Note to self, disregard any posts by this guy.

Ok. So explain to me how a aluminum transmission case DOES NOT act like a massive heatsink? FACT! Countless people on this and other forums have seen up to a 40° temperature drop just by installing one? Lets see how it works. Motor heats up, then the heats transfer to the motor plate which transfers the heat to the case which is in constant air circulation. Yup you're right doesn't work. Clearly the plastic case is far more superior that dissipating heat. Not only does the aluminum case dissipates heat better it also eliminates flexing. The stock case when it heats up gets softer and flexes easier which can cause damaged gears. There is a reason why almost ALL other manufactures especially the racing platforms and including older Traxxas racing models uses a metal motor plate and nitros uses a massive cooling head and aluminum chassis...B/c is does dissipates heat more effectively.

[orca44]

Morning guys..... I am leaning towards the new Proline Performance Transmission as it seems to have a bit more flexability than the others mentioned. I just wish it was available today!!!! I hate waiting

My motor and ESC temps are not overly high but warm enough to be on the side of caution.

Since I retarted I mean retired last month I have had plenty of time to practice driving daily on our track here at the house and what a difference track time has made.

I'm glad I have two Slashes to share the ware It sure has been fun wearing out the Badlands

Going to see when that Proline tranny is available....Have not seen it on any sights yet but will try again today.

Again, thanks for all the great input!!!!

If you want the benefits of heat reduction without all the added weight...you could try this one, Hot Racing hybrid nylon/aluminum (here's the listing I bought it off of). A few others here have used it, I just installed mine on Saturday. Took it to a local skate park and temps didn't go above 100F with 2s. You can feel the heat being sapped up by the mounting plate and the little blue aluminum heatsinks. And it's really tightly built...as in, there's no wiggle room and everything lined up, no mods to get it working like I hear with some of the full aluminum ones mentioned above.

Now if you want to drop the dough for the Proline one go for it, that thing looks flipping amazing and a sealed diff would be sweet. I got this one to PREVENT me from spending that much though because I knew I would if I waited till it came out For $28 though, I figured I couldn't go wrong you know?

Oh, and it looks sweet

I personally feel your transmission is a better design the Prolines. Is that adjustable suspension mounts?

[orca44]

Toyboarder..... I also liked the tranny you have so I will order it today for one of my Slashes.

Now I did order the Proline Performance Tranny this morning and will install it on my other Slash. It should be here by Thur or Friday at the latest.

I will post pic's and performance review after testing this weekend. Maybe the Hot Racing tranny will be here as well.

I would strongly disagree. I have been running a FLM case for years and love the thing. It drops motor temps by about 30º adds rear toe in, and allows for anti squat adjustments. Made a huge difference in how the truck drives.

[O.G.]

I do agree an alu transmission weighs more than the stock plastic case but it's well worth the added weight. Now I'm curious as to how much extra...

[orca44]

Fedx just delivered my new Proline tranny and I am off to the garage to do the install....

Keep ya posted.

Got the Proline trans in my slash a few days a ago. I did a little testing in the front yard with a 19T/86T ratio. No performace changes at all. As a matter of fact it slowed down overall. My sons stock VXL slash (ratio 90T/23T) was running circles around me. I will be testing some more this time at the track. Very smooth and quite trans but have not found any ups to it.

That's how and where I purchased mine.... Should have install completed right after lunch. It's tough changing the tranny in a truck

What was your gearing before? I run the same gearing 19/86 in the stock tranny and plan to do the same with the Proline as it came with an 86t spear.

[Racer XXX]

I was running 23T/86T w/VXL set up. I wanted a little bit more torque so I went with a 22T/86T and all was good till i got the PL trans. With a 22T/86T on stock vxl trim the motor felt like it would not unwind. Like I said my sons truck was out running my with no problem. from start to finish. They I went to 19T/86T and it some what helped but now I have no top end speed. I am thinking i have a bind within the PL trans. I will be call PL now to talk to a tech there for help. One other thing I noticed with the stock trans you can rotate the rear wheel by hand and they will spin freely a few times around before they stop. The PL trans does not spin free at all.

[orca44]

Well here is my mini review of the new Proline Performance Transmission....

There are no instructions enclosed with the product. Package instructs you to go to their web site for installation instructions, which I did. You would most likely would not need to use their instructions but I did just for a reference and guide line.

The change over took me about 1 1/2 hours and actually went very easy. My RPM bumper and wheelie bar attached to the tranny just fine....One of the 3mm X 30mm screws could have been about 5 mm longer but thus far it seems to be holding up just fine.

The tranny comes with a 86t spur grear which is the same as I had in my stock tranny. I installed a new 19t pinion, the same as I used in the stocker. So no gearing change. Proline does not have any other spur gears yet but in the works.

The 5,000 wt tranny oil is thicker than I had been using and the freewheeling that I had with the stocker is significantly less with the Proline.

My motor is a Castle SV2 5700kv 4 pole, and I have been using this motor for 13 months.

Now the testing...
1. First thing I noticed was the "Traxxas whine" was reduced by 30%
2. In the loose soil over hard pack using full throttle starts, the truck still pulled to the right but about 40 to 50% less than before.
3. I was able to corner faster with less spinning out (alot easier to control in the turns. And I did not notice too much pushing in the turns.
4. I was also launching a little straighter on the jumps.
5. Couldn't find my temp gun to ck temps but I was able to touch the motor for 5 sec or so before having to remove my finger. There was alot of heat transfer to the metal motor plate.
6. The tranny freed up alot after running as the oil thined due to heat.

Here is a few pics...
Just out of the package

The tranny is a little pricy but thus far it seems to be a good product.

Again, thank you to every one who chimed in with their opinions and suggestions.

One other thing I noticed with the stock trans you can rotate the rear wheel by hand and they will spin freely a few times around before they stop. The PL trans does not spin free at all.

I spoke with Matt over at PL. The drag in the trans he explained is the oil filled diff. Which now makes more sense now. The first test run at the track went well. Corners and jumps more in control. also motor temps stayed low. I did notice the weight went up.

[rag6]

What would oil inside the diff have to with drag of the gears outside the dif? If the gearbox does not spin free, its a bad gearbox period. I dont understand... I could see if it has to be broken in maybe, but thats different than what Matt from pl said to you.

From the post you quoted (yours) it sounds like you lost performance, and a lot of performance at that. I would be pretty upset to spend that much for a downgrade...

[orca44]

The oil in the tranny is quite heavy (5000 wt) and adds a little drag at first but after a lap or so mine free wheels just fine. And seems to get better with every battery pack, 6 packs @ 20 min ea thus far and will do plenty more today.

Racer XXX, you may want to give it some break in time as rag6 referred to or go with 1000 wt oil.

After the first battery pack mine has been "all it can be". Maybe just run it for a bit more???

[rag6]

There should be no oil in the gearbox, just the diff! Use lithium grease for the gearbox gears and the supplied silicone oil inside the differential.
Just in case someone was adding that thick oil inside the gearbox.

If the gear mesh is loosening up and spinning free after some running, then that is normal, even for the race brand trucks. These competition level gearboxes tolerances are very tight and precise, and need to be worn in to work to their highest efficiency.

[orca44]

Oops my bad... I should have said "oil in the differential". I stand corrected kind sir. I personally do not use any grease in the transmission portion...Do you think I should?

Ran 3 more set of batteries in it today and I like it more and more .

[rag6]

A little white lithium cant hurt. Was there any recommendations in the proline package for grease?

[orca44]

There was no mention of grease in their package or online instructions. In the past, about a year ago, I tried using some grease in the stock tranny but it was not the white lithium grease. I used the grease in an attempt to quite the "Traxxas whine", but the grease I used did not agree with my stock transmission, cleaned things up and never tried anything since. I take it you use grease in your tranny? And your professional opinion is???

I know some people are thinking that this performance tranny is a little pricey, as I did at first, but when you consider all that comes with it, the case, motor plate, differental, tranny gears, gear cover, bearings, clutch and spur gear, it is actually a fair price and comes completely assembled

[Racer XXX]

Yes I agree with you orca44. I will give it more break in time. If I do change the diff fluid you think it would corner better on a lose track?

[orca44]

I think in a lose soil track you want both wheels to have more of an equal bite and the heavier oil helps both rear wheels to drive more equally. This could cause the truck to push a little in the corners but on our track at home I like what the heavier oil has done for performance, so far it does not spin out as much, (since both rear wheels are driving) in the corners as my other Slash, which is set up the same except transmission.

With the extended run times I have on the new tranny it now has alot more coasting when I let off the throttle.

I also like the little tether attached to the boot on the clutch cover.

I have the clutch spring adjusted at 1 full turn out from full closed... Good traction and just about the right amount of slip for our track, (running Proline Trenchers) and will try a new set of Badlands today.

I spoke with Matt over at PL. The drag in the trans he explained is the oil filled diff. Which now makes more sense now. The first test run at the track went well. Corners and jumps more in control. also motor temps stayed low. I did notice the weight went up.

Diff fluid won't cause resistance of the trans spinning. It will only make resistance as far as the diff action goes (one wheel spinning forward and the other spinning backwards). Kinda sounds like the guy at PL didn't want to admit that something is wrong.

A new trans will surely takes some time to break-in, mainly the bearings. But it shouldn't make the truck run noticeably slower and hotter. That it an issue with something binding. Most likely the tolerances of the cases are not so good.
