    I just put new headgaskets on and did a valve job, while removing the intake, I broke the plastic end of my trans throttle valve cable, so when I was done the headgaskets I put on a new cable and adjusted it like the Haynes manual says to, now the trans shifts hard and late on the 1-2 shift, could it not be adjusted correctly? 88 350 tbi 700r4 with no "shift kit".What is the best adjustment procedure? /forums/images/graemlins/k5.gif

    If you didnt modify any of the brackets or mounting points, you can usually loosen the cable at the mount so it slides forward, open the butterfly to WOT, then pull the sleeve part back all the way and secure it. This will give you maximum pressure at WOT and sufficient pressure at low throttle use so you dont slip the clutehes. Another way is to attach a pressure gage and while engine is idiling, pull the TV cable tension until the pressure just starts to rise (3-5 psi)

    Heres a pretty good link on 700R adjustmemt procedures

    Sounds like a lack of vaccume to the modulator to me.
