Ummmm....yes. That's the point.

However....one omission the 6060 seems to have, that the Magnum does not is the internal oil pump.

The Magnum is superior to an older T56 in many ways:
All the internals are made from a better grade steel
the gears themselves are wider (handle more load/torque)
output shaft is 31 spline vs 27 spline
the case itself weighs about 4lbs more due to additional webbing/casting material (less deflection/gears moving around/wear with big power/racing)
parts are actually available to rebuild them .... some older T56 parts are not easy to source and the option is Korean made parts vs OEM
A stock magnum will shift light years smoother than ANY older T56 (pre 2008) plus they have no issues shifting at high RPM's.
I'm pushing 1200rwhp thru a 100% stock Magnum shifting at 7800rpm (LS9 longblock with 88mm turbo)... there are built 2JZ's making 1500rwhp+ shifting at 10K RPM on stock gears/shafts etc running mid 7's@200mph!
warranty with it

downside: COST $3395

It'd be interesting to know if the Grannas car is still on stock gears. I know it's faceplated...but no idea of stock gears. If it is, that makes it even more impressive !

Overall though, the Magnum is a bargain for what you're getting.

Certainly with purchases in the UK...the vendor has to handle the warranty, as essentially the contract you have is with them. At least for an initial period anyway, it may revert to some sort of direct contact with manufacturer after a time period.
No idea if it's different over there.

Grannas just ran 7.25 at 200mph in their Supra with a faceplated Magnum.....which they say runs stock Magnum gears, just faceplated.

That's one seriously strong transmission !

It is indeed a true bolt in deal guys, minus the yoke being bigger, which may require a u-joint change. Here’s a pic comparing the two. FBody magnum is the shiny one. They are dimensionally the same. No surprises here.

I run a TR6060 in my S10 and it's the best shifting trans I've ever used, Short positive shifts and never miss a gear.

I presume this Magnum has the extra protrusions inn the casting for the oil pump, compared to the old unit ?

This causes issue with my QT Bellhousing, and required a lot of grinding !

I'd say a standard bellhousing, and the QT Magnum specific unit are of course fine though.
Also, on my converted Magnum, the BH fastener art around 7-8 oclock was in a slightly different location

You are indeed correct sir. I tried to upload a pic of the front but can’t tonight for some reason.

I am going to put this here.

I am going to be in the market for one of the used units coming out! I would love to spring for the new one, but I need to be realistic about my need for a brand new shiney!

Send me a inbox if you are looking to offload the old working unit!

So guys, wanted to update this post. The magnum is quite the upgrade. For my application, I needed a stronger box. It’s a 70’ Chevelle with a 434” with 750ish hp and I have the limiter set to 7800 so I’ll shift at 8k plus rpm. The t56 wasn’t going to make it very long, just being realistic about it, and the thing just wouldn’t shift at anywhere close to 7800, so the stronger box was a must have item for me and the shiftability (is that even a word?) was a bonus.
What you get with this F-body magnum, besides fitment, is a box capable of holding 700 ft lbs and the smoothest shifting available. The gates have a very solid feel and you absolutely know when it’s in any gear. There’s a firm, positive feel when it goes into gear thats unmistakable. It gives you a new confidence of knowing when to release the clutch and accelerate hard. Kinda hard to explain with words. Simply put, the t56, while being a great tranny, felt sloppy (compared to the magnum) and hated rpm, while this magnum feels so sharp and positive and easily shifts at rpm. In fact, I think it shifts easier with rpm, than when cruising. All in all, it’s the perfect match to any performance oriented build. If your out there wondering if it’s for you, or necessary, or even worth the trouble, let me help you out. Yes, yes, and yes. You won’t regret the move. I should have went magnum when I built the car to start with, I just wasn’t aware of the actual benefits and difference that the magnum would make. It’s a different driving experience altogether. Looking forward to the next drive!
Want to give a shout out again to Mark at NorCal Motorsport, aka gnx7, for the deal and great service.

so no stock fbody ratios which sucks, I love having an overdrive gear......**** that the purpose of 6th gear for cruising....even if I cut back to a 3.40 gear in my 9 inch I can get 1-3 basically dead on with 2.97 gear set as my t56 with 3.89s (I really enjoy this combo) but im goona lose overdrive no matter what. all I care about is having .50 6th but that can be done.

also I know you will just tell me to contact tick, but isn't the fmagnum the same as their 3.5 bolt in magnum? why are t]hey asking 1000 more for this?

you can have them built with whatever ratios are available.

And 5th and 6th are always overdrive gears in these boxes.

No, any old adverts were Magnums converted to F fitment which required parts/time/labour...hence additional cost.
So they're a parts transmission, not a factory F.

Although no doubt they will be offering the factory F Magnum too. Some may change some small internal parts while it was apart for the conversion though, also at additional cost like the blockers on 1-2 I think it is, and brass pads or other minor differences

Yessir, Tremec will put any gear combo you want in the box, and 5&6 will always be overdrives. I personally think the close ratio is the way to go. My t56 was a wide ratio and the FBody magnum version I just purchased is a close ratio, which is much, much nicer to me.

I know they are considered overdrive but I'm goona lose the low rpm gear in favor of a more power gear. sorry but I must be the odd ball out who considers 80 to 85 cruising speed aka flow of traffic.

who the hell wants to be pulling 3000 on the highway. u have 6 gears for a reason, they dont all have to be power gears unless ur doing miles, maybe because back in the day 65 mph was 3200 rpms or more and it was more accepted. I'm sorry, but I don't wanna use up more fuel than necessary in 5th and 6th. save 1 to 4 for the fuel pissing.

lol and a 2.66 gear with only 450 wheel hp was useless with 3.89s, let's just make it a 2.97 to really make it useless on a 3500 pound car.

then 1.70 second gear was 90% usable on street tires on a hot day, but barely usable at night time in 50 degrees. let's just make 2nd a 2.10 so that this year becomes mostly unusable. great we now have a 4 speed tranny because 1 and 2 can't be used under full throttle. it has 2 usable power gears and an overdrive that will cause ur fuel mileage to be half, as well as the motor revving 1000 more than it has to rev to accomplish the simple task of driving to the beach....ok rant done
