I've had both. the TKO is a piece of junk compared to the T56. it shifts like crap. the ONLY advantage of the TKO, is that it's smaller and requires less hacking to put it into a classic.
the T56 is amazing. shifts like butter. simple to powershift, gear ratios are perfect for a 26" tire and 4.56 gear ratio in the axle. the only downside is that it's so bulky it requires extensive amounts of hacking to get it into a classic mopar.
power levels...I think they are probably both the same. the TKO is rated to 600 ft lbs, the T56 (viper spec) was "factory rated" at 650 ft lbs. both have seen much higher levels without any problems. I think the viper guys say the T56 is good to the 950 mark before they start looking for other options

I'm a t56 owner. I love the .050 6th with 3.91's , 2000rpm at 80mph. Mine is out of a Viper and it has the close ratio 1-4 and with slicks I predict low et's this summer.
Mopar to the bone!!!

This guy is selling 2 for $1200 each.
not gonna find a Viper box for much less than that, unless it's total scrap and needs a full rebuild.

I saw his CL post and really debated it as this guy is about 20 miles from me. The only reason why I didn't pull the trigger is I don't really have time right now to pick it up and one of the shifters looked pretty long (as if it was out of a truck).

T56 Magnum close ratio all the way! Although I am a little biased... Replace the rear seal with the updated version Use the stock shifter with the beefy seal and you should be good to go. Can handle 700 hp/ft lbs which should be more than enough for our planned 426 engines but if you ever happen to break one, a replacement is as simple as a $3000 phone call away Has a mech. or elec. speedo output Don't even bother with the reverse lock-out solenoid it not really necessary I have done a bunch of stuff to my car but by far the T56 Magnum has made me smile the most

For reference, my research has found the Viper T56 has been superseded by the T56 Magnum [TR6060 base]. Just so it's out there that the T56 Magnum is -not- a "Viper T56". Apparently better and stronger in several areas. The specifics evade me at the moment however. That said, I am finding myself wanting to spend the money on a brand new transmission [T56 Mag] rather than a used one out of a "Super Car". My luck with used parts isn't all that great..

I remember reading up on the differences, and they are subtle. both transmissions use the same main case, but I think in the TR6060 (T56 Magnum -- a TR6060 with a TKO tailhousing instead of the OEM tailhousing) the gears became thinner to allow for wider bearings which helped up the power holding capability. There were also some other minor changes with the shift detents, reverse lock out, etc. that allows the newer version to be more easily swapped to aftermarket applications--it has more "direct bolt on" shift locations available. the OEM T56 only has 1 shift location and requires complete tear down and custom modification if you want to convert the front inspection plate to a shift location

The Magnum/tr6060 Viper version are same internally except ratios. They both have internal oil pumps and the GEARs are wider for power handling which made the synchros and sliders narrower.

The Vipers do not have a pump. Only the 2015 Viper and Challenger have the pump. The Corvette and Camaro have the pump. The Corvette's mid plate is totally different. The mid plate on the Viper is partially machined to accept the pump, but the shaft needs to be have been drilled to make it work! Here is a 2014 Viper mid plate showing the pump recess. Notice the pump nose shaft cavity in the plate is not machined and no bushing present. The oil passages where the cooler fittings attached are also not machined.

Your right, they were both supposed to since the introduction of the 6060, they just never did it until '15. That's Tremec's fault, not Chrysler. We even watched the MasterTech vid on it at the dealer!!
Both cars still take ATF+4.

I run a TKO 600 because it's what I got a deal on (private party new keisler 'kit'). I'm happy with it. Swapping to a .82 OD soon and I'm sure I'll like it more (from the .64). Mine shifts well, and was relatively easy to install, as part of the tranny crossmember got to stay in the car. If starting from scratch, I would personally choose a t56 magnum OR a t56 viper ($1200 used). But anything on the list from the tko and up should work great for 95% of the builds on this site. I rank the available transmissions: T56 magnum TR-6060 mustang / camaro / viper T56 viper tko 600 tko 500 tko TR-6060 challenger t56 F body My

Is that a primarily road course driven decision, I assume? I was looking at the 0.63 'mag
