Thanks but it was checked out and was running and moving just fine for a few miles and then nothing.. That is the same support that has been with the transmission for a long time. None of the balls were missing . Thanks


That’s exactly what my transmission did with the blown input shaft seals. Drove car and put 10 miles or so the first time and about 15-20 the second time it happened. Was fine and then jumped in it the next day to go for a cruise and nothing.

have you checked the case it self for cracks at the valve body ports? could be causing an internal leak across two ports.

Yeah, the first go around one of the seals was gone completely. Second time the seal was Teflon, and was flattened and distorted. And as far as your friend with the Cope transmission, he’s the original builder of mine....

just throwing this out there but the small thrust washer on the output shaft somehow didn't make it on one of my builds and it acted a lot like what you are describing.

Are you talking about the two teflon seals on the pump or the steel seals on the input shaft ?

The seals were on the input shaft, there’s 2 of them. The replacement seals were Teflon on my trans. They are in the pump area so I would say that they are the pump seals. Honestly, I don’t know anything about transmissions, just sharing what I was told to be wrong with mine as it sounds as you are having the same issue. But yeah, the seals were Teflon on the input shaft and was told when taken apart by original builder that he must of accidentally damaged the seal when installing the pump.

Thanks for the info. I know just enough about transmissions to understand how they are supposed to work and mine don't LOL

Update to anybody still reading this long story. Last ditch effort went ahead bought a new reaction support and oil pump for this thing. I also had A&A send me some new seal rings too. They should be here tomorrow. The case is not cracked but we did find the front alum drum with some groves in it from the seals. I was told that if anything it would cause a little problem shifting into high gear but wouldn't cause all my problems. Hopefully the reaction support and oil pump will fix this darn thing.

If it fixes it take a good clear picture of the inside of the reaction shaft - the "tube" that's pressed in to the reaction shaft support. There are holes inside - take a few good pictures showing these holes and make sure you show the outside of the support too.

Well the new pump did not fix it. I replace the complete pump asy and front sealing rings. No difference at all. I did check line pressure and found maybe 20 lbs of pressure in 1st gear , around 90 lbs in second and around 130 in high gear. I checked the rear servo and in reverse it had around 150. I turned the pressure up on the valve body but no change in my line pressure. Any ideas ?? The car will move if I rev it up but not good. " yes Mark I am still screwing with it " LOL

Any update on this one?
I have a TF that acted the same way the last time it was in a car & has not been fixed.

The question I'd be asking is why is there only 20 psi in 1st. The only component applied in 1st is the rear clutch. Why does the pressure rise in all the other gear selections? The pump must supply even more volume to additional components that are applied in every other gear other than 1st. If there was an internal leak beyond the valve body 2nd and 3rd pressures should be even lower than 1st. Think on that.

What tap did you check to get 20 in 1st, 90 in 2nd and 130 in 3rd. Be specific and accurate.

Hey guys it's been a little while since I have been on here. Sorry for not replying . I figured out how to fix it. LOL
I bought a pretty new CRT Pro Race transmission from a good friend of mine. Works like a champ now.
On a serious note I never did figure out why the transmission just stopped pulling. Merry Christmas. !!!
