Hello all, I have a 2008 Jeep wrangler swapped with an LS3 and 6l80e supermatic. E38/T43 combo for ecu/tcm. The last bit I need to figure out to get it perfect is the ability to hold the trans in a certain gear. Currently TUTD works like a max gear selector, and no matter how I alter the TUTD shift control tables, it still behaves like that. The OS on the TCM is 24256125 and the ECM is 12639835.
I am assuming the ability to hold a gear with TUTD is in the OS itself rather than in the tune? Can I get any guidance as to if that is correct, and if it is, what kind of OS would accomplish what I'm looking for, and is it compatible with my ECM.
Attached is my current 6L80 tune.
Thanks in advance. T43wh1_0025.ctz
