Damn man what are you doing to these transmissions? How does that 9 second Colorodo guy do it "We've never had a trans problem, ever" and he is using a stock trans with a shift kit.
Just ordered the one piece billet overdrive planetary from ckperformance. It's the only one that is a one piece complete billet unit on the market. The others I have found only have the top hat that is billet and there are 4 pins that hold it in place. Long story short, shouldn't be having any more problems with ripping the splines out of my overdrive planetary.
On a side note, still waiting for information on the converter. The company received it this morning at 8:30. Owner is personally going through it this time.
Ok so heres an update. Got a call from the converter guy today, The lockup clutch in the converter is toast. Still not sure of what caused the TCC to drag. Pump is chewed up on both sides where the pump gear is located. Converter guy suggested I install a line to lube valve. I explained I installed the Sonnax line to lube valve the last time this happened, fixed the problem, but its already installed. Also installed the boost valve, from Sonnax as it came with the transbrake kit from Rossler.
Now heres what I am thinking is going on. I think the pump being worn and bypassing fluid, not building enough pressure is causing the TCC to drag because there is not enough pressure to deactivate it. Now what is causing the pump gears to wear both sides of the pump housing. Crank walk? Ive never checked it, but the engine has been going for 6000ish miles. Something inside the transmission walking back and fourth? If so, what could it be? PCM tuning for the transmission? What should I look for?
All I know is I have lost two pumps now. Both have done the same thing. Gears ate the pump body. First time was on a hard pull, shifted into 4th at 135mph. Lost everything. Second time occurred when I hit the transbrake for the first time. TCC started dragging.
What's the converter to flexplate clearance?
Do you have anything limiting fluid pressure in the converter? Alot of guys will limit the converter feed. If the converter gets too much pressure in it and baloons, it could shove the pump towards the tailhousing and eat into the face there.
If it's shoving it the other way, then I'm not sure. There's really not anything else that ever engages with the pump gears.
As far as the planets, the stock ones almost always fail due to lube and not power. Look into ensuring that they are getting properly lubed
