Someone suggested pulling the cable out and putting a vise grip on so tbat it like in passing gear all the time. Would that b better till i can get it hooked up. Thanks

    Cheers, not sure what year car you have but most Buick th 350 kickdown cables go through the square hole in the firewall and hook to the gas pedal inside the car. Hope this helps. Tim

    TSGP is right,I think up to 72 the cable hooks up to the gas pedal.The upper part of the pedal has 2 slots.one for the carb cable,the other for the downshift cable.That cable should have a roundish black plastic ,the cable goes the gas pedal,that black piece holds it in place.Bruno.

    Bottom cable with the clip. You won't hurt the transmission driving without it. It does make a difference in the shift points though.

    So, I’m in the process of changing out the original ST200 from the 68 Skylark and have a 72 TH 350 to go in. I just started looking in this forum for tips & tricks and stumbled in this one first. I need to get the TH350 rebuilt and a new flex plate and torque converter. Also need the kick down cable. Are there any critical adjustments to be made? My Service Manual is for the 68 and doesn’t list the TH 350. Any help would be appreciated!!

    If the torque converter that you have is fine and its not a SP one,it will fit into the 350 with no problemI think any 350 transmission up to late 70's maybe even later the cable will go in,even if a trany made forthe hoock-up to the carb,as where it goes into the trainy its the same..I also have a 350 flexplate,in case you want a good original and save some money.Bruno.

    Hey Bruno thanks for the help. I haven’t had any issues with shifting so I’m assuming the torque converter is fine. I looked around a bit as far as a new flex plate and noticed the price for a replacement vary greatly!
