has any1 done a swap to a 4l80?
or does some1 know of a website that can lend a hand since the 4l80 is larger than the 4l60 any suggestions would be nice

 

Go with the 60 series...infact I will trade you trannies!!!!!! Mine has 18K miles on it!!!

 

actually, if I were building a good auto tranny I would want a TH350 or if wanted mega power TH400.. 350 should hold though..
give it a manual/auto valve body..
3500-3800 stall.. life would be fun...

 

NO HE DOESN'T, HE WANTS MY TRANNY DAMNIT

 

well it has a 6 spd in it now and i need a 4spd auto for the daily driver i know i can pick up a 4l60 for bout 500.00 and a built 4l80 for 2500+ verter but what i would like to know is if any1 on the fourm has done this before

 

the 4L80E would cost about double what shapiro said. i was looking into this optino until i found out price and a few other very important variables:

parasitic loss would be big...this tranny weighs app. another 100lbs. than the existing 4L60E. you will lose app. another 20rwhp from this tranny.

the 4L80E doesnt fit in its current form. you CANNOT buy that tranny and expect to toss it in and have it fit perfectly, it wont happen. there are companies that make the "conversion kit", however, youll need much modifying to the underside of the car.

the only way it would be worth it is if you are pushing big big hp. im talking over 800 at the wheels. other than that, its not worth the price and hassle.

 

Shapiro, you can have my tranny for free, I will trade you even up!!!! If you decide to go this route let me know, I am first in line. I have 18K on the tranny and has seen the track once. My dad owned the car for the 1st 14K and it was just driven to work back and forth..he is in his mid 50's and never abused the car. Let me know.

 

Supersport thanks for your opion , and it is well noted.
now you stated that you have see " conversion kits" if you could please maybe pass alone the info that would be great..
and 6speed i have 2 6speeds at my shop( out of corvettes) would you like to do a trade for your 4l60 i know someone that could use it.

 

What year Corvette? I was under the impression that trannies for LT1/LT4 cars wouldn't work with an LS1...and that the LS1 vette 6 speeds were different than the F-body LS1 6 speeds. Anybody else wanna chime in here and correct me if I am wrong?

EDIT: Also where are you located, if its close enough could I drive to your shop and we could do the swap there?

 

6speedZ28, you must be dying to get a 6speed..

Why for?
Just curious...

I know my A4 was way faster than my M6..

And that was without converter.. If I had a converter I am sure I would of had a 12 sec timeslip.

 

My old Z28 was a 6 speed and I loved driving it, I just like shifting gears, plus all the women said it was sexy to see me take control of the car like that

 

haha my g/f said the exact same thing girls seem to like the M6's heh

 

I guess they liked to watch you play with your stick

 

Shapiro, where you at my man, let me know.
