Ok, so I took the pan off, and what to my surprise did I find?

I must not have seated the retainer ring on the pressure regulator, cuz it blew out and was all on the pan bottm.

so I put it back together, but am still having minor issues.

It shifts late from 1-2, seems to shift fine on 2-3, car wont go into 4th gear, and when in 3rd gear, if I let off the gas and then hit it again,it slips for a brief half second before engaging.

anyone have any suggestions?

 

What kind of shift kit did you use? What kind of car and the year? Also go over the shift kit instructions and MAKE SURE you did EVERYTHING. I was soo sure that i missed 2 steps it is very easy to miss something.

 

yah, the car is an 89 T/A, 700r4 trany.

the "shift kit" is the BM shift improver.

I am pretty sure I got everything rigt...

I wa thinking that the TV cable is not adjusted properly?

 

Once again, YOU DO NOT HAVE A SHIFT KIT!!!!!!!!!


There, I feel better now. As to your problem with your NON shift kitted tranny, how were the shifts before you DID NOT put a SHIFT KIT IN???

If you had good 4th before then, assuming you took the Servo out then you likely cut the Teflon seal on the outer piston. This is easy to do (ask me how I know!). If you did not then I suspect the band could be toast since it is on in 2nd and 4th but uses a different Servo. You may have enough force to apply it in 2nd but not hold in 4th with lower pressure/RPM. I say this since your late 1-2 could be a slip delaying the shift, even if it comes in "firm" that could be what is known as a slide-bump shift, where the bump is missinterpreted as a "good" shift. If you are not sure of the TV Cable setting, do this: 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.
