TCM Tuning

[racinmike77]

Can anyone tell me about D5030? What is the purpose and has anyone changed the values?

Also how can I fix my rough 3-4 shift without tearing down my tranny? It is built so I guess the C2? is applying too hard/fast?? Help?

It simply allows you to specify different throttle opening percentages that the TCM considers to be Wide Open Throttle for different transmission temps.

The values in D5030 affect the 4 tables below that one.
