Tremec T-56 Magnum "F" - Please Tell Me this is real!
#21
Their rating is for something maybe hauling 5000lbs or something daily.
In a car application, much lighter, even if it's raced....they just handle a shitload more.
I think Grannas are in the 7's with a Magnum ?

These are shipping now finally! The 2.66 1st and .80/.63 5th/6th would be my choice... my 88mm turbo LS9 RX7 will be getting one of these by October! Finally no more custom setback shifters needed!
Hats off Tremec! You guys finally made it happen 😁🍺

I probably have the one of the highest HP car's at a decent weight (3495lb at time) with a converted Magnum. I never broke it. To compare I just recently killed a GForce FP gearset T56 on similar power.
This transmission will be killer and handle well over 700ftlb of tq if precautions are taken to reduce shock load (tq management, clutch slip technique and/or slipper clutch).

Quick question, the T56 Magnum and new T56 Magnum F use a slightly different face to bolt to the bell housing than the original Borg Warner T56. On the lower drivers side a chunk is removed, from what I understand Tremec did this for a mechanical throw out bearing provision and located a new bolt hole location upwards a couple of inches, thus this transmission cannot use one of the 8 original bolt holes. The video from Moto IQ at about 9:32 shows they did not use the T56 bolt hole location or the new relocation that Tremec has provisioned. I assume this is acceptable, we can use 7 of the 8 bolt holes? Or does Tremec recommend we replace our bell housings with a newer one that has the relocated bolt location for the Tremec t56? I notice the QuickTime bell housings have a total of 9 bolt locations, assuming exactly for this reason.
Thanks guys, very excited about this new transmission option!

My quicktime did not fit my Magnum without modification.
Although I see they do now offer bellhousings intended for a magnum.
I just re-drilled the offset fixing hole and added a new stud, no real issue there. The awkward bit for me was the castings on the front of the box for the oil pump and galleries ( not used in the magnum though ),. These sit proud of the front flange of the box, so I had to do a lot of grinding to make clearance.
I think the old OEM bellhousing would probably be fine though. My QT BH was a very early FBody one, with just a flat steel flange at the trans end. TBH, even for the original T56 it needed modification too....seems they had issues when they made the first lot. They even drilled/tapped the bloody fixing holes the wrong thread.

@amandato- the T56 Magnum and new F style version have a front bearing plate that allows either hydraulic or clutch fork operation to make it more universal.... so when you bolt up the Fbody '98-02 style bellhousing it is true that there is a hole below where the hydraulic lines poke out from the slave (4th gen style)... plus you don't use all 8 bolts like the factory version. I've installed lots of them and never heard of issues due to the hole or lack of bolt(s). One thing I will say time and time again... is that it shifts light years better than any pre 2006 T56 ever will. Plus the gears and shafts are made from a better grade steel, the case weighs 4lbs more due to additional webbing/thicker casting, already has the 31 spline mainshaft and handles 1000rwhp pretty much with ease. It's hard to argue on the price when it can do all that with a warranty! There is a Quicktime bellhousing to adapt it to a 2JZ and there are guys making 1500rwhp+ and shifting at 10,000rpm with the T56 Magnum. That is even more impressive!!!! stock gear sets... not billet

It comes with a Tremec shifter, which I assume is an improvement from a factory 98-2002 shifter (love to know how it feels compared to stock). Just move over your factory shift lever and **** and you should be good to go. My current T56 in my 2000 Trans Am has a MGW shifter. Hopefully I can swap over my MGW shifter right into this trans when the day comes as I absolutely love the MGW shifter.
Full disclosure, my 2000 Trans Am original t56 is fine, but it is nice to know this is an option if I ever need to replace it. More relevant to this conversation, I am in the process of swapping in a T56 Magnum into my 81 Trans Am. I am almost done with the swap, cross member set, custom driveshaft made, and adapted the center console to use a Lokar shift boot. I just need to bleed the clutch and finish the wiring. When I see a warm day here in Ohio I will take the car on its maiden voyage with the Magnum, it should be the drive of my life. So far the swap has been straight forward other than floor cutting and making rookie mistakes like trying to use the plastic clutch centering tool. What makes this transmission slightly better than the Magnum is that a 98-2002 F body t56 puts the shifter in the perfect ergonomic location in a 2nd gen F-body (T56 Magnum vs T56 magnum "F").
The forward shift plate on a factory t56 is fairly thin, where-as the Tremec t56 forward shift plate is thicker and removes a little more clearance at the forward end of the transmission tunnel. In a 4th gen f-body it should not make a difference in the tunnel. For my 81 swap the clearance was only really an issue at the two most forward bolt heads to this plate. I ended up swapping those 2 bolts with button head bolts, I believe they are M8-1.25 pitch bolts, one is 25mm and the other is 30mm long. Hopefully that helps someone reading this some day.
