just had my 89 700 r4 complete rebuild, to include, vette 2000 stall, vette servo, all new clutches and bearings/bushings with hd governer. very reputable rebuild. i am no trans guy. first drive, 1st to 2nd still seems to "float" a little and 3rd comes in to quick, (imo). i know tv cable and geo has to be right. but, the builder hooked my lock up to 4th gear. fully aware that i need help with the tv, what worries me most is after it goes into 4th and lock up, shortly after it will drop back to 3rd. sometimes from take off it wont even go into 4th/lock up, but when it does, shortly after it will jump back out. im fairly sure thats not tv cable related. builder says poss to stiff gov and i am bringing it to him, but am curious as to what would cause that.
