4l80e guys come in!!!
I will be finishing my setup hopefully soon and I have a fully built 60e but i dont think she will last long once again. This is my 3rd in the car. I was leaning torwards a th400 reason being the strength and I have a 98' z28 so i would have to buy a stand alone or get a 99pcm. Now i have came across a deal on a 99pcm so i am leaning torward the 80e. I just wanted to know some info on how you guys like the 80e performance wise, what converter, power and times.

Besides the wiring differences, there are pcm differences regarding the vss. About all a 4l60 tune will do on a 4l80 is 3 rd and reverse i think. You could move a car in a shop, and thats about it. Its painless anyways to just have the 4l80 os system patch done.

It's a H/C/bolt-on car and it dynoed at 427 rwhp on a Dynojet when it had a M6. I did dyno it with the A4 on Mustang load dyno with the CC unlocked, but I don't remember the number.
Bottom line is I went from 12.6x with the M6 to 11.62 with the 4L80. My trap speed is about the same 116 mph. Best 60 ft w/ A4 was 1.62 and I think I can do better once I get the launch down and some cooler weather.

This turns off all of the solenoids and puts you in 2nd gear (on a 4L80e, a 4L60e limp is 3rd).
If you disable the codes (P0785, P0740) it shouldn't detect a fault. All of the electrical hardware is the same (some years even share part numbers).
Solenoid A operation is the same on/off sequence. Solenoid B operation is the EXACT OPPOSITE.
In theory (I will be testing it this weekend) if you hook up a 5 pin relay and use the Normally closed pin to ground solenoid B (pin 87a on the relay) it will reverse the operation of solenoid b, making it operate with the same commands as a 4L80E.
