So right around 100K miles my transmission in my 98 K1500 Chevrolet went out. Rear planetary exploded. So I took it out and took it to a guy at the local transmission shop to have it fixed. Put it back in and it ran great (until 30K miles later) it started showing some odd symptoms. Reverse would bind up (felt almost like the e brake was on) and it made a loud bearing or gear type noise in Reverse and 1st gear but went away after shifting into 2nd. Sometimes it would go into reverse and then just slip until it finally grabbed and it would grab hard. I knew it wasn't good so I just took it easy on it until I could get a loaner vehicle to drive. I never drive this truck hard anyways just a daily driver and pulling a trailer occasionally but nothing past the capabilities of this vehicle. This time I decided to buy the rebuild kit and service manuals and tackle this job myself. As the old saying goes "if you want it done right, do it yourself". It was my understanding when the first rebuild was done, the planetaries were upgraded (to what I assumed was the 5 gear planet assemblies from a 4L65E) but I doubted it when this happened again and after dis assembly my thought was confirmed it had the same old 4 gear planets as stock.
I initially took the trans pan off and discovered alot of metal shavings and gear teeth and knew what the gear salad culprit was, that rear plantetary again So here we go again. I'm already at a G note in parts on this one AGAIN!!!!!!
