Well gents, it's time for me to finally live up to my screen name. My SS is receiving the big, bad F40 6-speed. The kicker is I'm installing a Quaife LSD as well. Diff install and tranny install will be done by me. The diff swap will be goin down in a couple days. The tranny swap will happen when ZZP's 6-speed conversion becomes available again. I hoping it will be this Friday! Fingers crossed. AFAIK I will be the first 6-speed LSD HHR SS ever. Super pumped!

 

This will surely be a mod that I find interesting.

One question. What shifter will you have to use with this setup ?

 

Buick 6-speed shifter, and is said to be smooth when mated to this specific trans. This will probably be the most time consuming part of the swap but ZZP does provide you with detailed instruction. I think I remember seeing that there is minor welding needed, no big deal. If you can do a cutch job easily on these cars and you have some fab skill you wouldn't have a problem doing it yourself if you wanna save $

 

How about taking photos as you do the swap for a write up. We'd all be interested in seeing the process unfold.

 

With this being the most complicated project I've ever attempted on this car the last thing I'm going to be worried about is my camera because I only have 1 week to complete trans swap so I won't be making a "how to" but there will be plenty of pics.

 

Plenty of pics will do the trick.

 

Check. Too bad that beautiful diff has to stay hidden.

 

Neat set up, six gears of tire ripping fun! Cool!

 

6 gears are nice and the gearing in this specific year of trans is ideal for racing and staying in the powerband of a turbo car. I be cruising at 2800rpm @ 80mph. The BIGGEST benefit of this trans is it's strength. Will hold nearly twice the torque as the F35 due to the 3 shaft design as opposed to the 2 shaft design of the f35. I only wanted to mess with the trans once. No gear shredding will happen with the F40. Some cobalt guys are putting down over 600hp on the f40 without issue. Unlike most, I worry about the upgrading the trans before making over 400hp. Once it's installed, the steps to get to 500hp will be easier.

 

Dang but I love looking at sexy internal parts, they'll sure do the trick for you Xtreme, very cool!
