    What did you guys do to keep the tranny fluid from puking out of the hole where the cable attaches to the case?

    For the tranny to shift properly in normal use, the cable must be installed and adjusted correctly. The cable attaches to the detent valve in the trans and directs regulated modulator pressure to the 1-2 and 2-3 shift valves. It provides WOT downshifts and part throttle 3-2 downshifts. There is no reason to run without it on a street driven vehicle.

    As Barraza said no sence in running without it unless you don't feel like running to the store to spend 10-20 dollars on a new one. On the other hand you don't need it to shift up you just need it to shift down when your on the skinny pedal. You can always manually shift it with no problems, but the decision is obviously yours. Only time i've heard of that you really need it is with a 700r4. The kickdown kinda acts like a life line for your tranny... /forums/images/icons/grin.gif

    Mines not hooked up. Ineed to fab a bracket for it since the old one won't work with the vortec heads. Its been like that for about 2 yrs now no problems, but I never drive it on the street.

    If you dont have a manual\automatic valve body.. and you take it off... you are eventually going to kill that automatic valve body. Just be ready to replace it. I did the same on my monte carlo. No kickdown, with ratchet shifter. Blew it. installed manual/automatic.... never had a problem since... But I must say.. without one.. eventually, it sucks @ss.

    Ya, especially when it shifts into 2nd and you want to pass someone. Impossible without that kickdown and these 39.5's.

    Your '85 has a TV cable (if stock 200-4R) the TH350 uses a detent (kickdown) cable, totally different animals.
