No I didn’t not, I read the thread you sent, it involves some testing which I don’t know how, plus I’m not sure of the location (detent switch), and I don’t want to screw up

If it’s the kickdown switch by the gas paddle, that has a single wire connected to left side (driver side), yes I disconnect it, drove the truck, nothing it’ll not shift.

I appreciate your help
