First you need to have a stock file to compare with. If you do not have an original file from your PCM before any modifications, check HoldenCrazy.com for one. Load your current file and then use the stocker to compare with. Note any changes in the transmission area of the program. Shift points by RPM and/or vehicle speed do not matter. Anything that has pressure or shift TIME will need to be matched to the stock file.

So just to make sure, under category transmission, there is General, Shift at Speed, RPM, TPS, TCC, Trans Pressure, Desired Shift Times and Torque reduction.

The ones that I need stock is Trans Pressure and Desired Shift Time is that right just to make sure so that I wont break my new trans?

Do a compare and see what is actually different. There might not be too much. If you are unsure, post both files.

The only tables that are pressure related and modified are D1108 and D1109 for the 4.10 TM Stock Pressure.tun vs. 02 LL8 Stock PCM.tun. Is that your newest file or is it 3tune1_update1.tun?
You may want to check with FLT on their Torque Management requirements if any.

they said that TM equalling to 0 is fine. Thanks for the help!

See tables D1108 and D1109, they are related to pressure.

but what about the trans pressure?

D0701-D0703 shift pressure tables... they already look stock.

I don't see any tables for mapping the PCS solenoid.
