could anybody help me.....i have a 89 formula 350 with 700r4 tranny. i havent done a thing to the tranny no shift kit nothing....but it is rebuilt....twice actually anyways....when i first got the car it shifted from first when cruising at around 1700ish rpms a smooth shift now its shifting at 2500 and if i try to manumatic it it wont shift into a higher gear...another problem with it is that when i raced it before i put it in drive and powerbrake to 1200 rpms dumped the brake and floored it. worked well......well i tried doing that again and it is shifting at 3000rpms when i floor it....missing 1500 rpms of power.....whats wong with it and how can i fix it?

 

Check the adjustment of your detent cable(do a search, it's been posted many times). If it's correct, then drop the pan and check to see if the detent valve is sliding properly.
- Pull the governor, remove the gear(make sure it's in good shape) and pull the "apple core" and clean everything thoroughly.

 

much thanks....would a shift kit make it worse??

 

Well if it is the detent cable you should tet it fixed. You can burn up a trany if it issent set right. A shift kit should make the clutches last longer because there isent as much slipping between shifts.

 

alright thanks guys much appreciated....

 

what is the apple core??
