I have recently transplanted a 700r4 from a 92 rs into my 88 Iroc. When I removed it it worked fine now it shifts lazy. does anyone know what may be wrong?

 

TV cable adjustment?

~M~

 

Tv usually moves the rpms where it shifts


I'll put this where it belongs.

 

Start here: To adjust the TV Cable skip the book method and do this: Press the 'D' shaped lock button on the adjuster and loosen the cable setting (The black housing that the metal cable is in will move forward). Now, have someone floor the gas pedal while you check to see if the throttle plate is open all the way. Usually they are off a little and will wiggle. Do whatever you have to do to get it open solid. Now, with the pedal still floored, press the 'D' button and pull the cable casing (the black tube) back as hard as you can (putting maximum tension on the metal cable) and release the button. You now have the engine, tranny and gas pedal all in sync at WOT. Mark the cable casing so if for some reason it gets moved you can know where to put it again. The problem with the 'self adjust method' is that it bends things and puts them permanently out of whack. It is also the full TV setting, which is theoretically what the GM method does.

If that doesn't help there may be some differences between the vehicles, such as Axle Ratio which will change the "feel" considerably.

Now that I posted that I see your handle saying 4:10. Is that what you have now or what you had? 4:10's should make any Tranny bark.
