Is the convertor or trans bad?
I know nothing about transmissions but before I have this rebuilt does anyone have an idea? I think the front pump is bad or not building enough pressure until you raise the rpms.
Friday night we took it to TNT and when I tried to do a burnout the engine would rev but it would take a second or so before the tires would start spinning. I quit after three passes because it seemed to get worse. Driving home I would hear a "howl" every 30 seconds or so. It would only last for a second but it definitely howled. Car drove home fine but definitely did not seem right.
Any ideas? The trans is a turbo 400 with a transbrake and reverse valve body. I bought it used. I am not positive but I think that it was doing this when we first put the trans in but assumed that the stall in the convertor was just more noticeable.
One more thing. When you leave in reverse or low gear, even after it has engaged, the car leaves like a manual transmission and you are slowly letting the clutch out (slipping). I only notice it when pulling out of the garage and leaving. The more you drive the car the worse or longer it takes for the car to engage the transmission.
