Hi
I've got a small problem tuning the tranny of my buddys '98 Tahoe.
I tried to set the WOT Upshift RPM to 4500rpm but it allways shifts at around 5000rpm, which is the stock value I think. I tried serveral different values for WOT shift speed too. With no luck...
Strange thing is that 1-2 shift works fine.
Any ideas what could be wrong?
