The 5.5g is NOT 5AT, it's still 4 AT.
As far as i know, the only difference is the final drive ratio (3.619 4th gen and 3.7899 in 00+)

I am presently in the process of putting a 3.5 in my 4th Gen auto, I believe the 4th Gen auto is superior to the 5.5 Gen. It shifts faster and it will certainly hold a 3.5, it has already stood up to numerous 12 sec 1/4's with the 3.0 in it. I don't see any reason why a 3.5 will chew it up.

2 other points that i wanted to make were these:
1. The 5.5 gen is CONSIDERABLY heavier than the 4G, somewhere in the neighborhood of 300 lbs.
2. The 5.5 gen ECU allows for more ignition timing than the 4g 3.5 guys and the VTC's which make for more torque
Both of these things will make for far more stress than the stock 4g auto was designed to handle on a regular basis.

Until someone cracks open the 4 & 5.5g auto and proves that there is anything different we really cant split hairs w/o the facts.
I do agree with Jime though.
When my 4g 4AT was in its prime, it shifted much more crisp than my 5.5g, until i got the VB mod in my 5.5g.

If you're going to go through the trouble of wiring it though, just use the 5AT from the 04+.

Well I am not putting the 3.5 in the 4th Gen to baby it. It is going in for racing. I have put over 200 runs on the 5.5 this year already and next year will be more.
So we will so how long the auto will last.
Maybe my driving habits are much different than most people but I race almost every weekend, the rest of the time I drive like the Grandpa I am. I have no interest in driving hard on the street.
I know lots of guys who have chewed up 5.5 Gen auto's as well but I now have over 400 1/4 mile runs on mine over a 2 year period and its still going strong.
This is not luck, my other 4th Gen auto's have faired just as well.
Also you can put a 3.5 in a 4th gen but very difficult (maybe impossible) to put the 5th Gen auto in a 4th gen because of the TCU as Kev indicated.

I chewed up 2 gears already with the 5-speed manual so I don't know about trying to put an auto through the same abuse. I'll admit one thing though. I rape the transmission on a daily basis. I drive it like it's rented (Get it Jime? ).

The 4G auto is not up to it long-term period. I've already given two examples of ppl that blew their autos and these were in a lighter 4g chassis. In a heavier car the damage would be exponential.
