TC Lock Up Switch Help
I have the TC Lock Up switch installed and it works fine while in 3rd. Once I get the truck into OD and I manually lock the switch and then when I slow down to come to a red light and I turn the switch off the TC will not unlock. Any ideas why ???? Pete

Q1- Is this a "mystery switch" addition? If so...
Q2- Does it unlock if you have the OD switch off?
Perhaps it's finding another alternate ground connection thru the trans.
