I'm getting ready to order a Keisler auto OD kit for my 70 Challenger
( 440/727). Now that these have been out for some time and some real world miles driven. Can you that have had them give me some feedback on them? Any issues? Any installation issues? I'm not so bright at computers/electronics and the controller has me a little intimidated I must admit?
I have searched the net looking for negative issues , but all I find is issues with the tremec 5 speed. And not so good customer service after the sale if there is an issue. It's a lot of money to me and I can't afford to do this twice, so if there are any words of wisdom, please help out a Mopar brother and tell me now!




I was going to go with the Kiesler kit myself, but after they changed their kit and stopped including the controller (took $600 off the price, but the controller is $1000 to buy separately), i decided to seek an alternative and wound up ordering a kit from Phoenix Transmissions (they don't supply the flex lines or a drive-shaft, but I wanted my built locally anyway). Awesome customer service thus far (fast response,very knowledgeable and good customer feedback from past customers). They also build the trans and the converter and will dyno it themselves. They have been building these trans for a long time. I order one built to take 650HP, but they will build it to match your needs. It uses an adapter plate instead of a new bell-housing, but that didn't bother me as I figured a factory casting from GM should be just as good. If you want to PM me I can send you some more info.
