it has a cooler installed. the 4speed is just in temporarily but I am hoping to get the swap soon
I would hope so, too.

Here's the part that failed out of my 4-speed, which prompted me to eventually swap in a 6-speed manual transmission.

This part is part of the rear carrier assembly, which is the part that transmits engine power through 2nd, 4th, and reverse. Part of this rear carrier assembly is still inside the transmission. The rear carrier assembly decided to shred itself apart into two major pieces, at about 221,500 miles on the odometer.

In the background, you can see the rear annulus, front carrier assembly, and a couple of large snap rings.



Here's a picture of a complete and unbroken rear carrier assembly. The part I am holding in my hand would be the bottom part of that assembly pictured below.

WOW do you have a link or any info that you can share on doing a 6 speed or is that swap just for the hemi guys? 6peed manual sounds promising / fun to drive @T VAGO

Yep, the link is here:

Swapping an NSG370 6-speed manual transmission into my 3.5L V6 Magnum!

I do not support any V8 Magnums, as they have enough V8 support of their own. To the best of my knowledge, the V8 folk have never actually succeeded in swapping in a manual transmission. They apparently gave up trying, once the stick-shift V8 Challengers came out.

Well... Being as I can now fishtail on dry pavement, and experience wheel hop on an otherwise unmodified 3.5L V6, I'd say that I can feel the torque more clearly. You'd be surprised at how much power that 4-speed drains.

Not entirely sure that the NSG370 can handle the torque output of a supercharged V6, though... You may want to look at what the Jeep Wrangler folks are doing to beef up this transmission.

I know it's been a while since I posted but I just wanted to update people on what's going on supercharger is still running good and strong . Engine is still running good no shaking no banging no Etc. I found out through researching my VIN number that my model is a little rare it was the last Model of that year that had the 5-speed Mercedes tranny so through tuning the transmission shift a little better but it's still not a full manual like I want I know of people putting the T56 transmission in there but the electronics is still an issue so I'll wait until someone finds that part out

How much are electronics involved with a stick shift tranny? The only thing electrical that I've heard of with a t-56 is the skip shift that GM uses to force the trans to shift from 2nd to 4th for better fuel economy, and the skip shift feature is easily bypassed. The only other electrical issue is the speedo drive. If nothing else, the speedometer could be replace with a gps speedo, and the drive in the trans left unhooked. If the ecm needs to have speed signals from the trans, could you use Challenger parts?
