Hi All:

I would like to know how to modify the xmission shifting speed. It shifts to 4th. gear at about 40 mph and I would like it to be at 35 only.
I believe I need to modify the xmission electronic controller but I don´t know how to.

Thanks

The Trans Control Module (TCM) has no servicable parts and can't be modified. Check on line to see if other replacement modules are available.
