Gonna try and locate a 66rfe now
I've been looking off and on now for over a year. Like trans tec said they about 250 bucks more then a 545 and sell for 3700 if I'm remembering correctly. There are plenty of performance trans shops that have their own stand alone tcm units that may be able to tune these things. It ticks me off, FAST has had one for the Chevy units for some time but not for Chrysler. But there are others I saw, just have to search again. I'll put a stock one in mine right now, I'm ready...my truck is stock.
