HELP:::what is the best way to do this swap
HELP:::what is the best way to do this swap OK here is the deal, I have a 98 formula that used to be a A4, I swaped it to a M6 and now I am in the process of doing a 4l80e on the car. I am almost done with the physical part of the swap but I am unsure as to what I need to do for the PCM part of the car.
I was going to have a tuner load a 4l60e stock file on the PCM and just adjust for the converter....
I know I have to do some PCM splicing and add a relay in there some how (got the instructions)
any help would be greatly appreciated. I am almost to that point of driving the car.
thanks folks.

Running 4L80E trans from 4L60E segment If you already have instructions, then they would say:
- drive the 4L80E TCC PWM circuit from the 4L60E TCC signal (not TCC PWM),
- invert the 2-3 shift solenoid signal using a relay.
Those can be deduced from looking at the shift range charts and the TCC apply/release description in the HMTG books.
Those are minor wiring changes.

I have a couple of questions about the way to do it.
do you have some wires that will be disconnected entirely or ar they going to be used in the relay?
also what about the actual connector...is the U pin the one one next to V?

This is the reason and it makes the 80 behave just like a 60 with lock/unlock it is a world of difference.
ok I did the wiring today and found out that two of the wires are completely disconnected. I added the relay at the tranny plug as well. I was going to do it at the PCM but it seemed a lot easier down there.
over all it is not that difficult, I was just having a hard time reading the directions.
I will have the tuner delete the codes that need to be deleted when he comes to my house. I still need to measure the T56 crossmember to have it modified for this transmission, I dont want to buy a new one bc I ust purchased a tubular one for the T56 so I hope is not too many modifications that I have to do to it.
the car should be running by next week. I am taking my time bc I am back at school and my help works nights so its hard to get a hold of him.....
thanks for all who chimed in.
