manual valvebody 4l80e
downshifting to 1st every time you stop gets old-one reason i switched back to auto-you can program it to do anything
it did everything i needed, i drove mine mostly on the street, but also raced it, and shifted it man.-i would buy one again
It is a killer control unit IMO.
I've used all the controllers at one time or another and the Optishift is a new design, is more user friendly than most, and has a more friendly price too.
I'm a dealer for it and when purchased with a transmission we give a pretty nice discount.
We've tried to make the 4L80E an affordable option, and Baumann has made a controller that is affordable.
I ask because I will be getting a full manual VB with trans brake and i don't care if I have to shift it manually all the time but if I can keep the auto shifting capabilities then I will keep the wiring and programing for it
