T5 guys TKX
So I'm not a big T5 transmission swap guy. I'm a fan of the bango as designed and a 3 sp or od, But what does this do for the guys that are looking? Not having to hunt a s10 trans down?

Re: T5 guys TKX
It will be a much improved transmission over a T5 NWC box. I've not seen one, but from reading the specs, it is probably more like the modern Magnum tranny, but smaller, lighter duty, etc..
If you've ever shifted a Magnum (which is totally redesigned and not the same as the older TKOs - you feel a really nice smooth engagement, excellent). You have three different shifter locations on the TKX, so with the forward mount, should work pretty well in a Hotrod. Lastly, you have a whole range of gear ratios - I like the close ratio setup with the .81 overdrive - great setup for one of our cars: TKX-GearRatios.jpg |

Re: T5 guys TKX
If you drive the old 3 speed box a lot, you will get tired of coming to a stop before shifting into low. If you do it on the move you will eventually ruin the low reverse gear and probably the cluster too.
I have a TKO for my brand X 55 I am building and I will thoroughly enjoy synchronizers in all the gears as well as the OD. I am not thrashing this car like a race car so the 600 ft/lb torque rating is plenty good. |

Re: T5 guys TKX
It's not cheap. But it is an interesting transmission that spans a lot of yr uses being somewhat small. The cost of an old t5 trans is just the beginning when converting to open drive.

Re: T5 guys TKX
.
This is interesting, so let's do some comparing. The TKO and TKX are both aftermarket transmissions manufactured for hobbyists building cars like "hot rods", "Muscle" cars and healthy street racer types. They are beefy, they can generally survive the torque produced by today's healthy performance engines, and come with enough OD ratio choices that offer acceptable tuning for different "upper speed" requirements, especially when a lumpy, performance cam figures-in to the picture. It's nice to get the RPMs down while tooling-along at higher speeds, but you really don't want your RPMs in 5th gear to go so low with a performance camshaft that you end-up "lugging" the engine at too low of an RPM at normal highway speeds. In other words, that .64 OD ratio MIGHT sound great to get the RPMs down low at say 65-70 mph, but with a performance cam and a lower numerical rear end gear, or larger diameter rear tires, it's possible to get into a situation where you're lugging your engine with that "Gee-Whiz-Lumpety-Lump" camshaft at 1,300 or 1,400 RPMs, and that ain't necessarily good. The older TKO offers a .64, a .68, and an .82 OD ratio for just such occasions. The new TKX offers a little more diversity with a .68, a .72, and a .81 OD ratio. Since the new TKX and the older TKO can both be had with the same two choices of 'close ratio' gear sets, I would imagine that the slight (1%) difference shown between the .81 and .82 OD ratios is likely a "rounding of numbers" exercise rather than two different (and insignificant) OD ratios. I own a TKO 600 that I bought new about twelve years ago for $1995, shipped and no tax! This one has the .82 OD and was bought to go behind the lumpy-cammed L76 (365 horse) Corvette engine in my '40 coupe. That car has a '57 Ford 9" with a 3.50 gear, and I just didn't want the revs getting too low at 70 or 75 mph with that cam. And it has a near-perfect 2.87 1st gear. What I believe we have here in the new TKX is a "re-packaged" TKO, with probably some improved synchronizer pieces, as SOME TKOs have been reported to have problems shifting at over 6,500 RPMs. Tremec claims this new one shifts well up past eight grand. As can be seen by the pictures, the TKX's main and rear cases have been cleaned-up and made more compact when compared with the older TKO. The lumps on top AND the shifter location seem to be lower on the TKX, affording more tunnel room at top of trans. MOST folks ARE NOT going to break either of these transmissions unless 'stupidity' somehow gets into the picture. So, our poor little T5 tries to remain in the limelight. And it WILL! I've bragged on the T5s for years now. They are such a diverse design. As long as you respect the WC and NWC differences between early ones and late ones, you can swap parts to come-up with all sorts of configurations, as well as different gear ratio sets. ALL main cases are of the same internal dimensions, and they are still easy to find. They are affordable! Pieces are available all over the internet, and assembling them does NOT involve rocket science. And, they can be made to fit most vehicles, and do offer plenty of strength (If YOU'RE CIVILIZED) behind a flathead, or even a little Chevy. All three of these transmissions offer very smooth, solid shifting with a shifter located just a little ways behind the original shifters on Model As thru 1939 Fords. You can build a nice, close-ratio T5 for well less than a grand. DD The "TKO" 600 The "TKX" The Camaro T5/S-10 Tail Shaft Housing .......... |

Re: T5 guys TKX
With just a quick look, it appears that the bellhousing bolt pattern is different, unless it comes in different configurations. Everything I have uses the Ford bolt pattern on the T5, maybe not a big deal, but something to keep in mind.

Re: T5 guys TKX
I don't see anything about multiple shifter locations on the TKX. Did I miss that somewhere?

Re: T5 guys TKX
Just watched the promo video by Modern Driveline on the TKX and he implies that there are 3 shifter locations with one of them being a mid shifter similar to the location of the S10 shifter. Judging by the top plate it should be very close?

Re: T5 guys TKX
The TKX comes in BOTH configurations...Chevy or Ford. I don't think I've ever seen a TKO with other than the standard Chevy pattern, now that I think about it.

Re: T5 guys TKX
I agree with most of what V8 Coopman had to say, except I think it isn't all that easy to build a close ratio T5 for under a grand - including the necessary S10 rear section. I don't think I could actually do it (with me doing the work).
Most T5's come with a wide ratio gear set where 1st is practically useless . . . and the standard overdrive ratio is pretty steep (somewhere around .68 to .72 if I remember). I've modified them to put a .82 OD in, but there goes a couple hundred bucks on top of everything else. If you want to buy a close-ratio gear set, it is another $500+ . . . then you have to buy a rebuild kit, new synchros, etc - and do the work. (There goes probably another $150 or so in parts). My guess is that for an average guy to buy all the stuff to build a close-ratio T5, with a .82 OD, S10 rear housing . . . they're probably going to be well over $1500 - AND, they better know how to rebuild it (and most guys I know are not skilled in transmission rebuilds). When you start adding it all up (including your time and rebuilding work), buying a new TKX isn't a huge amount of money above that . . . Okay, just another Flathead Wacko's opinion - which is worth exactly what it cost to read it. |

Believe me, I understand the advantages of tailoring precise gear ratios when considering the likes of rear end ratio, tire size, camshaft, power bands, and more. That's precisely why my TKO was bought with a .82 OD ratio and the 2.87 1st gear. But the point here is that it is still possible to freshen a close ratio T5 that can put many happy (s)miles on your face for a grand or less.....with a .63 OD ratio! DD ........ |

Re: T5 guys TKX
Oh Hell V8 Coopman . . . I only wish I was a mere fraction of what you spelled out as my 'MO' up above.
If a guy was good at scrounging up all the right parts from cheap sources, they might be able to do it. Maybe when I "scrounge" I find the most expensive sources - then pay them extra for their time. Or, maybe I'm always in a damn hurry (as every project I work on, I seem to be LATE on . . . so then I have to pay a premium). This has been a good thread . . . and believe me, I want to take my TKO and NOT put it in my 34 Coupe (blown Early Hemi) - and buy a damn TKX! It is such a better looking transmission than the beast of a trans the TKO is. LOL Also, I bet it has the much improved shifter system that the Magnum has . . . like BUTTER, even at high RPMs! |

Re: T5 guys TKX
I was buying T5zs through Ford Motor Sports for under $1,200 with free delivery to the dealer. Purchased a lot of them at that price, then the price jumped up about another K! I think they are down in price a little now, but the cheap ones are no more.

I don't really consider this to be a replacement for the T5. It's a replacement for the TKO500/600 to make it more muscle car friendly.

Re: T5 guys TKX
Good thing is that maybe it will free up more of the old T5's for our flatheads.
