The 4l80 doesn't care where you shift, yes you can shift at 6400. Spin the motor until you drop a valve, then set the rev limiter a few RPM below that

The H1 has a 700r4 right? The stock 80e converter will stall a little over 2k RPM.

I think the H1 has the 80 because they came with the 6.5 diesel

yeah H1 has the 80 but I was told the stock 80E converter stalls less than 1500.

And I have one more question will I loose power by doing the 80E swap? I was told to expect 30rwhp loss
