Re: Anybody using a 6l80 in their swap?

using the same config file for the tap up / down pids,
Key on, engine off, dont want to start it:
Fluid temp 61ºF
In drive, it shows D6
Current gear 1
Trans Mode Normal

Trans Fast learn Disabled... not sure why I put that on there, but whatever.

when I put the Stock shifter into sport mode With my resistor setup, It does nothing to Trans mode. But when its pressed to tap shift up or down, it changes to

Trans Mode TUTD

when the engines running and in drive, it will change Current Gear accordingly



Schematic factory,
When in sport mode, it gets 12v and sends it through 8.25k resistor to trans, and when up or down, it goes through the other lesser value resistors.

to get out of TUTD, I have to go to neutral and back to Drive (D6). I dont know if it is like modern cars, where if you dont give it an input for xx time, it will default back to D6.... havnt driven it yet
