Magnum F

Atta boy! Keep finding the weak links.

Great post! I'm curious about the same question.

Hoping the Magnum-F fits same in the tunnel as a regular f-body T56. I'm using the Holley/Hooker engine/trans mounts in my Nova.

I've installed a bunch of the F style units as they have been out for about a year now. The only real thing you need to change from your standard T56 is the 31 spline yoke. Otherwise it is a bolt in and your other wiring connectors are plug/play.

I'm pushing over 1200rwhp thru a 100% stock T56 Magnum F style in my LS9 turbo RX-7 without issues (this car isn't in my sig). Runs high 8's@173mph and is a full on street car (3.31 gears in an 8.8" out back). I don't launch it hard as breaking stuff isn't my happy place. The shifting smoothness is no comparison to your older T56 and the .80 5th is great as you stay in your powerband better.... I shift at 7800rpm when doing 1/2 mile racing

That's a pretty good sales pitch. This goes inline with everyone else I've talked to that has any knowledge on the "F". I ordered one, along with the 31 spline yoke this morning.

Thanks for information vote that this is the right way to go.

Once the install process starts, I'll post whatever pictures I get.

Wait at Curtis.. if you have a t56 magnum already you already have 31 spline..
Asking because I am just about to order my driveshaft.. and according to research.. 31 spline comes on t56 magnum.

Ummmm... Yes & No. This is a confusing conversation to have and I've learned a lot the past few days. Thankfully some great people where willing to edumakate me.

So there is the T56, T56 Magnum and the T56 Magnum-F (I think there is also a T56 Magnum XL).

I currently have a 93-02 4th gen T56 that was rebuilt with a Stage 2 Kit. It has a 27 spline slip yoke. The T56 Magnum and T56 Magnum-F require a 31 spline slip yoke.... so you are correct in that part.

The T56 Magnum-F is a new version of the T56 Magnum (which is basically a TR6060.. for the most part) that is designed to be a direct replacement for the 93-02 4th gen T56.

The T56 Magnum and the T56 Magnum-F differ in that the "F" has three ways to mount the shifter and the tail housing is different. I'm sure there are more, but that was my takeaway.

Basically the "F" doesn't require any tunnel mods for me and will be a direct bolt in. (fingers crossed)

Clear as mud...right!
