E38 with T42 shifting through gears way too quick and dead pedal syndrome.

Looks like you need a 2wd OS

Is the only way to change the OS to 2wd to license a new tune from the repository? I have a 2wd tune from the repository out of an 08 tahoe that uses the same OS 24239927 as I am currently running but it has different numbers in the trans ID and CV section and a different CVN # in the diagnostic section.

Try segment swapping them

Try segment swapping them

I swapped the t42 and trans segments from an 08 silverado 2wd and it worked for two drives which is better than I have had. I will let it sit overnight and see what the morning brings. Thanks for the help man!, I am learning more and more about these gen IVs through every headbanging session...Guy is bringing in an E78 swapped jeep next week, I have heard those are not very user friendly to mess with so should be interesting.

Did this ever get resolved? I have the same problem
