Your shift points (wot) are controlled by the governor in the tranny, and if that hasn't been modified, then 5,000 rpm is perfectly acceptable and is what is normal.

See my comments over on the FTT site where you posted your PL file

It doesn't seem like my combo likes to make power at higher RPM's....thus maybe not seeing anything over 5,100 RPM or so throughout the entire run each time.

I doubt that the governor was messed with during my rebuild. I didn't specifically ask them to do anything with it.

Does it matter that the 2-3 shift comes up much quicker than I expect it to? On the street, it will shift 1-2 normally around 15 MPH and then it will be into 3rd by 25 every time. I would think that it would climb to around 40 or so before shifting into 3rd. Ideas?

Thanks so much for your replies thus far.
