TREMEC TKX 5-speed manual transmission POSTED BY: STEVE BAUR NOVEMBER 6, 2020
TREMEC, the leading manufacturer of manual transmissions and components, announces the release of the new TKX, a 5-speed RWD manual transmission developed solely for the aftermarket. “We listened to our customers, combined their suggestions with our OEM technology and strengthened our aftermarket line up with the addition of the TKX,” says Mike Kidd, aftermarket business unit manager at TREMEC. The all-new 5-speed, single overdrive manual transmission from TREMEC was designed, tested, and built specifically for the aftermarket.
For the development of the new transmission, TREMEC engineers took a forward-looking approach to finding the best and most efficient solution. This included universal packaging, excellent shifting performance, and extreme durability.
The three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension). Gaskets at all flanges simplify installation and eliminate fluid leaks. The transmission is designed for multiple to fit applications with three shifter locations and an overall compact, end-loaded design that provides clearance in most transmission tunnels without floor modifications. Separate GM and Ford case patterns and input configurations are available.
Internally, the TKX features a robust design with internal three-rail shift system and steel shift forks. All gears and shafts are made from special grade steel (ASTM 4615) providing increased torque carrying capacity, and a wide gear width increases gear life and a 600 lb/ft torque capacity, while at the same time, noise, vibration, and harshness (NVH) performance is optimized with a gear layout to best control stress levels. One of the key characteristics of the TKX transmission is its outstanding shift-ability at high RPM (up to 7,500) to match modern, high-performance engines. This was achieved by using multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon. Additionally, a single overdrive reduces engine wear and fuel consumption for comfortable roadway driving, and the transmission os offered in multiple gear ratio configurations (See chart below). Connecting the transmission to the engine and driveshaft are a 26-spline input shaft and a 31-spline output shaft for added strength.
TREMEC has also equipped its TKX manual transmission with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean, crisp shifts, and a built-in reverse light switch and cruise control safety switch provide additional functionality for street car applications.

This looks like a good replacement for an 833 or an auto to manual conversion. I installed a TKO years ago and it functions pretty good but the flaw with them is the 2-3 shift. You can't do high rpm shifts with the TKO but this new trans fixes that. The TKX is $2795. Not a bad price considering that a T56 Magnum 6-speed is $5000 and Passon's 5-speed is $6000.
If Tim still had his red Valiant that is the transmission that I'd try to talk him into. That Valiant really needed another gear. It also needed EFI but that is a slam dunk to install these days. The TKO was available back in the day but it was too much of a weak sister to install behind the 427 that Tim was running. A six speed was just too much of a good thing to install in the car.
The TKX is $2795. Not a bad price considering that a T56 Magnum 6-speed is $5000 and Passon's 5-speed is $6000.
A T56 Magnum TUET11009 should not be $5 grand, we sell them for way less than that, just to clarify. Maybe if you factor in a Quick Time belhousing, and an install of that trans it would be around that price.
This new TKX looks interesting and glad that Tremec is still catering to the 5 speed market.

You're right Ariel, I was going off what I've got in my whole set up. $4,745 from Dederichs. The T56 is for the Valiant but I've got the TKO "Perfect Fit" from ol' Keisler in my 'cuda. Silverport says the TKX should be a direct replacement without the need to even replace the driveshaft. This TKX sounds great for those of us who have bought TKO kits and have always wanted high RPM shifts.
I'm just glad you're having fun with all your projects with manual transmissions! Stick shifts for everyone haha!
Definitely not having as much fun as I should be. Bunch of wrenches in my plans. I bought a 76 D100 that I did NOT need and it's taking money away from the 'cuda. If I sell that I will be buying one of these TKX 5-speeds to replace the TKO and sell that as well.
Can the new tkx be had with the same direct fit mods as the tko?

I don't think the mods have to be done, at least on B & E's. The tunnel shouldn't have to be cut. Upon viewing the TKX case, it is somewhat more rounded on the top of the case. The TKO has a shifting fork inspection cover on top the transmission case cover that is tall enough that it requires the transmission tunnel to be cut and have a piece of sheetmetal welded to the tunnel. The TKX has a one piece case, no cover on top, so it is lower sitting in the tunnel.
It also looks like TKX has more shifter locations , at least fore and aft, so that it can accomadate the different locations the shifter hole is in between the different models. It may be in the middle and not slightly offset to the driver's side like A833 and SST/Keisler shifter locations though.
I called and inquired about what it would take to put my TKO Perfect fit kit into a different car, specifically a big block, and was told that they were specifically fitted to a certain model. I couldn't put the kit in say, an A-body or B-body, but if I wanted to put it in another E-body with a big block the only thing I would need would be a bellhousing. The crossmember and throwout bearing is the same. I am guessing this is because Keisler modifies the TKO case and the shifter turret location specific to each bodystyle. I think that the TKX would fit easier across the board and not HAVE to have modification to it's case or the car that is recieving it.

Kiesler hasn't been in this business for well over 10 years.
My bad. I’m meant SST but as far as the modifications go it’s the same as Keisler. They are the only vendor, to my knowledge, cutting the tail of the TKO’s and moving the shifter over to come out the stock location. I bought my “Perfect Fit” kit from Keisler but Silversport has handled any tech questions and service parts I’ve needed. I said Keisler but mistakenly. You didn’t know Silversport (SST) is Keisler’s successor?

So typical of me....forgetting how others might interpret the things that I say. In this instance, I really didn't mean to be rude. I was just trying to make a correction. I am sorry for being blunt on the response.

SST is planning on offering up to 25 shifter application/locations, some of which will involve offset brackets to the shift tower nub to position the shifter in the stock locations or as close as possible

It's cool. You know the internet, hard to capture emotion and sentiment. It is all good in the hood. Admittedly, I say the wrong thing all the time.
