That is not the "magnum." It is rated for 700lb-ft ... 450 wouldn't get the job done much better for many of us with modified Coyotes.

I think one can be purchased (not installed) for a bit less than $3k.
Just an FYI, I had BG Syncro Shift II in my trans when it was replaced due to heavy trans whine. They had the entire trans apart as part of the diagnosis and found the bearings which were the cause of the noise. I got a new trans with no trouble from the warranty department.
The fluid that came out of the trans went into a bucket to be disposed along with all of the other used oils from the cars they were working on.
Not too bad if it performs the way we need it to.
Did you take it in with all the mods listed in your sig? I'm concerned about that as well, especially the tune and off-road x.
All mods in my sig remained. I have stock cats in place however. I simply called my selling dealership and talked to them about mods. As I've had this discussion on AFM about 3 billion times(everyone over there fears their warranty) the dealer told me as long as the mods did not cause any problems the repair is still covered.
Your dealership sounds like a bunch of pricks like my local dealer.
I was going to try the BG Synchro Shift II
While no doubt the Magnum would be a great performance increase for the big-power guys, I really like the gear ratios of the MT-82 for the naturally aspirated 5.0. The closest ratio'd T-56 I've seen was on the Steeda website.

Ratios......MT-82..........Magnum..........T-56
1st..........3.66.............2.97/2.66........2.97
2nd.........2.43.............2.07/1.78........2.07
3rd..........1.69.............1.43/1.30........1.43
4th.........1.32..............1.00...............1.00
5th.........1.00..............0.74/0.80........0.80
6th.........0.65..............0.50/0.62........0.62
For the Magnum with the 2.97 1st, you have to get the wide ratio overdrive which I don't like. The T-56 looks a lot better, but has a 450ft-lb rating compared to the 700 ft-lb rating of the Magnum.
I'm not a "gearing expert" but with those kinds of ratios, I assume you'd be better running a 4.10:1 rear-end again like with the 05-10 5-speed?
