*OVERDRIVE PLANET:
The OD planet is notorious for cracking the splined pieces and or stripping the splines. This can happen from a 15 sec Olds to a high 9 sec car. This piece is going to need to be addressed to continue to put hard power to these transmissions. I was really hoping someone else would step up and make the OD planet and ring gear, but everyone seems to think that it's a losing effort. It will be the next part addressed by us but I need to gather my bearings before we take on any more. I have two ideas in the works, but right now they are just that, thoughts and ideas, but I do have people on it. Wish another company would get involved. *UPDATE!!!! Mike Kurtz (Century Trans) has stepped in to assist, test , and back this project!! Alright Mike!!! Together, with the NEW Billet splined OD planet , we may have solved this too!! We will keep abreast.
88GTAinRI said:Wow. That was some good reading. I am having a problem with my overdrive planetary. Let me give you a little back ground. I bought the car (1989 TTA) in MD. I was driving her home to RI and I punched it on the highway it downshifted and then it had no gears at all. Had her towed home from NJ to RI. I removed the trans and brought it to a very reliable, very compitent shop. A friend of mine that specializes in performance transmission builds. The splines of the overdrive planet where wiped right out and cracked in two spots. He installed a new planet and an input shaft. I drove the car tonight and the same exact thing happened, only this time it was accelerating at around 100 mph. I am sure once it is opened up the splines are going to be a mess again. What should we be looking for as the cause? Is it just the part itself that can not handle the torque or is there another part/problem that makes the planet fail? Any help would be greatly appreciated. Thanks.
My guess(and its a guess) is your planet set is not geting enough oil. If it oils the same as a 4l60e you can cut 2 groves on the sun gear and eliminate the overheating that causes this. Someone else please tell me if im in the ball park.88GTAinRI said:The splines of the overdrive planet where wiped right out and cracked in two spots. He installed a new planet and an input shaft.

I take it the deep pan is not recommended for street use due to the pan hanging below the frame?![]()
