Anybody see any of these yet ? Looks a good bit smaller than the TKO 600

I was just looking at the TKX today, looks like they took a 600 and made the case smaller. Slight differences in gear ratios too. Looks neat
-
I here it's a Hand Cuff design too
-
I’ve known about it for quite awhile, they’ve tried to keep it secret.
The Tremec page has a lot more information, a lot more gear ratios are available than what’s advertised. A lot smaller footprint, lot more rpm capabilities.
-
So the synchro package is a modern design, not the antique setup used on the TKO600?
Shifting into third at speed would be possible?

A lot of the issues there were because of manufacturing tolerances between the gear cones and the synchronizers. If you take them apart and correct the surface finish, as well as adjust the thrust clearances, they will normally zing right on up.
Tremec is advertising these to be 7500-8000 rpm capable, so I think that they're trying to make up for lost ground.

I saw that today on my FB feed, pretty cool for them to make that revision. Would have been nice to not have to cut the floor in my car to make it fit, wasn't a huge job but always nice to keep the original where possible. Looks like they took the square "shoulders" off the top of the case exactly where mine hit. I don't have enough cam to hit an RPM where my TKO shifts balky, but have heard plenty of feedback about it being an issue @ 6500.
-
Whats the MSRP going to run on it?
-
$2795.
Hopefully be available end of this month.
-
Are they stronger than the regular TKO
-
Tremec's website lists the same torque capacity, 600 lb ft.

If I remember correctly, you mentioned in the past that you could do things to the TKO to reliably increase their torque capacity beyond the factory rating of 600 lb ft. Please refresh my memory as to how much.
With your knowledge of the TKX, do you believe it's torque capacity could also be reliably increased? Presumably, neither would approach the 700 lb ft capacity of the Tremec Magnum though, would they?

Normally 10-15% in addition to factory torque rating. That’s with cryogenically treating the parts and some REM polishing.

Not bad. I may have to find a new home for my TKO600 and upgrade.

Any idea how these torque ratings are determined? I would have to think that 400 ft-lbs of torque launching at 5000 RPM on slicks would stress a transmission more than rolling on the throttle at, say 3000 RPM at 30 MPH with street tires, with 600 ft-lbs.Anybody know what a small shaft as well as a big shaft Toploader 4 speed would be rated at? I have talked to a few people with various Tremec 5 & 6 speed transmissions that said they did not like to be shifted at WOT power shifts, even at only 5500-6000 RPM. Has that been adressed? I would consider swapping the wide ratio Toploader in my 59 some modern style OD transmission, but not really interested if you have baby it.

From what I gathered many years ago when the TKO 600 came out, they are put on a dyno and a continuous amount of torque is applied to them. It's not a peak rating, it's a continuous loading.
As we've discussed up above, this new transmission should address the higher rpm shifting issues.

I have a TKO 600 and that's been my issue. My Comet is a BP 482 FE, 630tq, 650hp. WOT shifts @ 55-6000 RPM are always an adventure. Plus, it HATES going into reverse. Doesn't matter what I do, it usually grinds. I was looking at the G-Force aftermarket gear kit for the T-5; my brother has an older T-5 that he would donate. They advertise that gear set as being good for 1000 HP. Any thoughts or opinions of that versus this new TKK?
Thanks,
Dan

The gear kit may hold some horsepower.....a stock T5 case will explode like a grenade.

The T5 is a decent transmission for a small block street car, I ran one for years in my old high 12 second 302 street/strip Fairmont, but the basic design is just too small to stand up behind a healthy big block. Maybe if you only cruise around, but not if you want to run it hard at all. The gear teeth are tiny, and as Brent mentioned, the factory cases are pretty flimsy. I just wish somebody made a transmission that was strong and easy to powershift at WOT, but with an extra gear for overdrive.

G Force also makes an inproved case too for the T5
-
I found this graphic online comparing the size of the TKX vs T5 and TKO. Are there any other dimensional drawings floating around out there? If small enough, I'll ditch my TKO and get the smaller case so I don't have to chop my floor up so badly.

I ordered a unit today from MDL. It will be a February delivery with the appropriate length input, disc and mounting hardware.
