    Trans issues

    3500 velineon on 3s

    I spun the diff again.....Is this trans to weak for 3s? Do I need a sealed diff??

    Not sure if its pilot error or parts failure?

    I do have a MIP ball diff in a box, will that be stronger ?

    Velineon on 3s can put out an insane amount of torque. That's for sure. I don't run anything above 2s (High C ratings) in my Slash/Stampede rigs for the simple fact that the Magnum 272 is only going to survive "so long" on 3s. Whereas it'll live forever on 2s when geared appropriately.

    3s is borderline uncontrollable from my experience. Hard to put that power down. Which I'm sure is fun for bashing. Racing, not so much. You want a certain amount of predictability and control.

    I would upgrade the diff to an all-steel unit if your heart is set on only running 3s.

    I had the same problem, I had a seasoned pro check out my set up and it came down to slipper set up and my driving. Going from reverse to forward or forward to reverse really quick was the biggest cause for me. How he adjusted my slipper was he set the truck on the ground, put the rear wheels in between his feet and throttled it forward, he set the slipper to the point where it would only lift the front wheels about 6in or so at wide open throttle, this made a huge difference. Once I got the slipper set right, I paid closer attention to my driving and I have never had a problem since. I run 3s with a MMP SCT set up and haven't touched the trans in 6 months now. Hope this helps.
    Just another bash addict...

    I'm going to strip it down, and see what is bad now

    Diff was dry, caused the spur gear 3696 to shed a few teeth

    I will use grease not diff lube this time
