Is there a way to change the transmission programming to lock this transmission in a selected gear? Like running a manual valve body? Problem is, it likes to jump around in gears from 1st to Overdrive. 1st is too slow and Overdrive won't hold it so it likes to shift back down instead of letting me get into the higher RPMs. I would like to be able to reprogram the transmission to where I can have a dual mode...street mode(normal shifting) and Off Road Mode where if I select 3rd gear is stays in 3rd gear. Doesn't shift down out of 3rd unless I select a different gear. The 545RFE is out of a 2011 4x4 truck. I have a 4:1 transfer case and DynaTrack D60 axles with 5.13 gears.
Can it be done? If so, who can do it for me?
