Hea Jake. Are you talking about tuning the tables on the aftermarket controller to shift the 80? Because I know some PCM's like my E40 on the 5-6 GTO cant do it while others like the E38 of the 04 GTO can?

It's pretty simple to tune the A4 tables to control the 80, lockup and all.

You COULD use an air shifter to upshift it if using a manual VB.
I hear you Jake.

I'll give you a call to figure my best plan.

If I can afford the 4L80E swap you offered - just use it's VSS and tune my LT-1 A4 tablles after a test drive

Other option is TH400 swap, auto w/governor.

Not so sure about a TH350 with my supercharger...

I have tried air shifter before, but I'm a street car -it was in the way around town.
I can push my bad hand forward to shift - just can't grip to pull back.

We have developed a method to run a 4L80E using a 4L60E tune as long as any ratio error codes can be disabled and the 3-2 solenoid codes.

So we are able to use a '98 PCM and some of the newer TCMs where a segment swap is not available.

Not quite following you. Are you saying you sell a custom built controller based on some OEM stuff? Or can my E40 PCM be made to do the job?

To the chase, can you get me EVERYTHING I need to put a 4l80 into my 05 GTO?

With EFILive, you can run a 4L80 on the E40 PCM. Hptuners can't delete the TCM codes.
