To use a 4L80E transmission on an LT1 ECU,

[Tinbender59]

To use a 4L80E transmission on an LT1 ECU you needto set the shift solenoid switches as follows:

Shift Solenoid A - 1st Gear - Enabled
Shift Solenoid A - 2nd Gear - Disabled
Shift Solenoid A - 3rd Gear - Disabled
Shift Solenoid A - 4th Gear - Enabled

Shift Solenoid B - 1st Gear - Disabled
Shift Solenoid B - 2nd Gear - Disabled
Shift Solenoid B - 3rd Gear - Enabled
Shift Solenoid B - 4thGear - Enabled

I will be using TunnerPro for this - it is free!!

Are you still trying to command PWM on lockup?

Are you still trying to command PWM on lockup?

NO trying to access the "A" and "B" solenoid control perimeters, I believe it is "A" that works in reverse from the 4L60E "a" solenoid, so we have to get into that parameter and enter the values above. My problem Is I do not have the correct mask or ??? what ever I am doing wrong as I cant seem to locate the setting as of yet, and "those" that Know where and how aren't sharing or haven't seen my pleas for help yet, LOL. I guess I can send the ECU out, but It sure would be nice to do it myself.

P.S. for those who care about such things, I did pay My $35 for a registration key for Tuner Pro RT, even though I am totally lost at this time.
