Hey i had my transmission rebuilt by level 10. its been a while since the rebuild but now I am experiencing overdrive too early. today i noticed the overdrive lockout doesnt seem to work. I do know for a fact the VB in the truck is not the original prior to the rebuild (Its in my garage i never sent it after my 2nd vb back oops) so maybe its possible i could have someone elses tired solenoid. why do you think i am having too soon overdrive issues and now no OD lockout? also whats the fastest way to diag. he offered me $100 to drive it to him but its not an easy trip.
