hey, my 400 trans my brother in law told me has no kickdown for passing gear hooked and he sees no way of hooking one up, i have the 403/400 turbo setup, and trans was just rebuilt before i traded for it, so what are my options? i now just manually shift down to the next gear. also it has a eldelbrock 4 barrell if that makes a diff. thanks.

 

B & M transmissions makes a kickdown switch the mounts to your carb linkage on the intake manifold. I installed one on my 455 on my 57 Olds, works great

All you need is a switch controlled by the throttle that provides +12V to the solenoid terminal on the trans at wide open throttle. You can either retrofit a factory switch or use an aftermarket one as suggested above.

 

thanks, ill check the 12v switch out for sure..
