Re: 4l80 questions

The MT DOTs you mentioned in the other thread are roughly the same diameter as mine and we are running about the same rpms, but I never feel the TCC kick in... should be in 3rd and 4th if I've read right. Maybe the line pressures in the un-tuned trans are so much smoother that I don't notice? That would only be for shifting though not the TC...

I've also used the torque app to test the rpms during acceleration up to 50 or so. I notice about 4 shifts, or distinct drops in rpm, but not the other one or two from the converter.
