I guess I will know for sure soon since I'm going to tear down this tranny once and for all in the nearby future.
Still, I'm curious if anyone has had the issue I have. The transmission SLIPS in manual FIRST just like it does in DRIVE. It takes a LOT of RPM to get the car moving from a dead stop.
REVERSE on the other hand works great.
I have rebuilt the front servo and upgraded the rear servo with an aluminum billet type.
I purchased the rear band but decided NOT to replace it because the one in the tranny looks brand new. This transmission is a 1977 TF727. It has LESS than 3K miles and I have had it for three years.
I was using synthetic fluid. My line pressure would read 50 PSI and drop to around 35 PSI once the fluid reached normal running temperature. Replaced the fluid as recommended by the TCI tech. Now it reads about 60 PSI cold and drops to around 50 PSI during normal fluid temperature.
I do get BLACK residue in the bottom of the pan.
I'm pretty sure that my CLUTCHES burned out when the T/C went bad. The car has been acting this way for quite some time. It needed more and more gas to drive off from a dead stop. Once it's moving, it shifts and down shifts OK.
Any similar experiences and/or comments are highly welcome.
This will be my first time rebuilding an automatic transmission but at least I picked on of the easiest out there to work on.
I LOVE this auto/manual transmission when it is working properly.
LG,
Mike
