Torque converter problem?
Took my '74 Fury for a ride after a lot of issues with my 727 to A518 swap and noticed that throttle response is not right, the car feels like a dog, the shifting between gears is really nice but on every stop light noticed a weird noise coming from the front of tranny, something like pressure coming out from somewhere (like pressurized steam) and this only happens with tranny in a different position than Parking (R,N,D,2,1,) but in reverse this noise changes for a different one like a hydraulic noise. While driving at steady speeds I can hear a "clunking" noise like something were loose, I though this was a driveshaft issue but I think isn't because the noise stays even at very low speeds so isn't consistent with car speed
I already told that the car feels like a completly dog, BUT! If I manually engage the lockup in 3rd and 4th gear, man! the car completly wakes up, throttle response is A LOT better and even the noise that I though was coming from driveshaft decreases
I think all this points to a torque converter problem, I had to replace the tranny stock converter (was destroyed) with a rebuild unit so I think this increases the chance of a problem
I'm not sure If I should discard a tranny issue because it shifts right, I don't hear noises coming from it and also I don't notice any slippage with the lockup engaged

I dont think Ill get off topic on the power issue. I will assume that this was a good runner engine before the trans issue....
I think you have a pump issue or a valve body issue and maybe possibly some miss matched parts..
I would suggest that you talk to the folks at PATC.... https://transmissioncenter.net//?swo...=transmissions

I suspect is a torque converter issue because the slipping feeling goes away as soon as the lockup engages and then I feel a huge different in performance, throttle response, basically it feels like a complete different car
if maybe the problem is the pump instead the torque converter, shouldn't I be experiencing other issues like erratic shifting, random slippage, gears not working? can a pressure test discard a problem in the pump?
