transmission shift
I am having trouble with my car shifting.It shifts to late.I have a cable thats below the accelarator cable that comes from the firewall and and goes into the transmission.Is this the detent cable and if so how do i adjust it?I have a 350 tranny by the way and my car is a 1972 cutlass supreme.
Thank you joe for your input.I will definitely look into it. |

I think that cable is the kickdown function for full throttle 3 to 2 downshifts, not upshifts.

The modulator valve and vacuum control the upshifts. A pinch in the vacuum line or a bad modulator could be causing this late shift.

There are 2 wires going into the top of my accelerator pedal.I know one is the kick down.What is the other one? I have a 72 cutlass supreme with a 350 rocket and 350 tranny.

Actually, the inner governor weights dictate upshift at wide open throttle, teamed up with the vacuum modulator. You can get a kit BY B&M and adjust the shift points. Works great. Works for the 350, 400, and 700r4 trannys. Was the 350 trans a transplant? If you have wires on the a switch mounted to the gas pedal bracket, that's for a 400 (electric detent).
