i know theres quite a few posts on fpr shim, but does it help much? i hold 65 psi fuel press. is it hard? more or less, is it worth the trouble?

next, i seem to have a lil weakness after shifts into OD and sometimes when cruising along at low rpms for a given gear. like lower r's in od or 3rd, but when it dont really need to downshift either.

and, why does 3/4 throttle not seem any less than full trottle at times?

ideas?

 

shimming you fpr just assures there is enough fuel if you do it though you don't want more than 80psi . Mine was at 55 and the shim went to 75.

 

c00nhunterjou has alot if info on the shift of our trannys. Check out his pics in his sig. He has a fix for the tranny.
