I have a torque converter shudder that ive had since i got the car. I changed the fluid once in school and it solved the shudder problem for alittle bit. When i got the new motor in, it was ok for a few weeks, but i drove around 5 friends one night and it started to shudder again. I dont have the time to change the torque converter yet, and i plan on putting a stall converter in when i do, but can i change the fluid again to hold it over until then? Im not sure how many times i can change it. Other than the shudder, i believe the transmission was rebuilt before. The front pump looks almost brand new and it shifts fine. I know i shouldve changed the converter when i was in there, but i ran out of cash and patience.
