Does this mean someone has the 3.27 gears working without going in limp mode?
yes i do. I have been working on this since December, the TCM I got from eroucharge did not work, but the one I got from Rudy and speed driven does work ,,for the last 30 days i have tested it up to about 140, and on the 1/8 mile track,,next week we go to1/4 mile track ,OH! if i want i can put a Dodge Challenger differential, and Axels with the 3.91 gears ,, it does Require quite a bit of rework of the rear suspension, only to mount it .. jim
