TH400 transmission Kickdown switch adjustment
« on: June 11, 2014, 09:22 PM »
The kickdown switch mounted on my gas pedal was not working.  Found an adjustment procedure and it now makes much sooner (was not making at all).  Will re-install the switch and see if this works.   :)clap

Tom where is this switch usually located on an RV, or at least on yours..?

Good work Fredric!  Looks like GM 1242101 is the original, no longer available from GM.  Haven't found a cross number yet.

Thinking if I had to replace one of these gold plated switches, I would at least try to fab up a switch bracket for the carb.  Lots of options, including some aftermarket kits available.  A nitrous switch would work to since it works at wide open throttle also.
