Can anyone look over this tune for me? It is for a 2002 LQ9 and 2004 4L80E that I installed in a 1981 trans am. I have swapped the intake and injectors from a 2002 LS6. I am having issues with the transmission not operating properly. The rear gear ratio is 3.42 and I am using 285/40/17 tires.

No, his OS is fine for the 4L80E.Originally Posted by Cantalope Kid
What is the transmission doing/not doing specifically?
At first glance it looks like you didn't calculate the speedo right since the sanity check is off.
Does the trans revs/mile value actually do anything? After reading the summary at the bottom of the window it is just there as a check.
What should the TCC Duty Cycle Minimum table values look like?
The trans revs/mile is what the computer uses for calculating shift points, etc. It MUST be accurate for the tranny to shift properly.
