I think the answer will be. Set your WOT Shift RPM vs shift to what RPM you want to shift into 4th say 6400 rpm. Then set your shift speed vs shift to close to what MPH you would be doing at 6400 rpm in 3rd. Assuming your 4l80E can take WOT shifting into 4th. I have no experience obviously but if Zippy says so I believe it.

Zippy is looking it over for me. I'm going to drop by the HPTuners website to see what I can drum up.

lol, its shifting WOT now and it seems to be alright.

This should be your shift RPM for 3-4.

This table is WOT Shift RPM vs. Shift- Normal. I would also change the performance tab to match the normal tab.

Your entire trans properties file should be stock, except for: removal of TQM; change of shift RPM; shift speed(mph). All other tables should be stock due to the Transgo.

why the hell would you force 3rd gear to run to 6400rpm before shifting to 4th? that's one impressive 6.0L to run to 6400 in 3rd.

Grippy, are you sure it's a 3-4 shift and not the converter locking in 3rd gear?

I was going faster than 80, but I'm not admitting to how fast

To check my sanity I dropped mine to third today and ran up to 80. 3300 to 3400 rpm here.
