Transmission Shift Firmness

Transmission Shift Firmness

Postby cameron626 [OP] » Oct 28 2011, 2:19am

I recently purchased a hypertech max energy programmer. I set the rev limiter to 6000 and raised each gears shift
point by 500 rpm. Under full acceleration the engine seems to freeze in between 1st and 2nd gear before a hard shift
occurs. Surely it can't be the rev limiter kicking in is it? Anybody else had a problem like this?

I have no experience with that one, but I had a friend put a Bully Dog in his 05 Duarmax. After the install, it started shifting bad. We called the support line and they said it takes time for the programmer to "learn" what it's supposed to do. It did finally get smoothed out by itself.
I'm not sure if yours will or not, but I figured I'd share that info just in case.

I'm pretty certain the instructions say that unless you change out the internals in the engine, you shouldn't touch the rev limiter (speed limiter is OK, as long as your tires are rated to handle the speed).

You probably should talk to Hypertech on this one... I recently put one on, too, and my tranny acts just fine. I only raised the shift firmness, though.
