I installed a 700r4 that I rebuilt in my garage. Its got a new torque converter with a 2000 stall, manual valve body, new pumps, kevlar bands and clutches, cool servos, and the lock ups gone. The engine is also freshly built, sounds like it runs great, and passes the compression test. The problem is that the car moves very, very slow under any kind of load. Could there be something wrong with the transmission and what do you think it could be? Or is the source of my problem in the engine?

 

hows your tv cable look? did you reset it or use a different induction setup and throw the geometry off?

did you put fluid in the tranny?

 

what method did you use to get rid of the lock-up? if you left out the lock-up solenoid, then you have a huge fluid pressure loss. if you didn't modify the tranny properly, it will mess things up. you can't just get a torque convertor with no lock-up clutch to get rid of the lock-up feature.
