I agree completely with the short throw shifter addition. I’ve driven a couple 500-600hp Mustangs with TKO’s in them and with the right shifter powershifting 3rd is really, really easy. From my experience they actually shifted better under power than just cruising around town. If the shifter doesn’t help it try checking your clutch setup, freeplay, etc.

These transmission have an inherent problem with the shifter rails..That cause this exact issue..There is a fix. But offhand I do not know where to find it. Google the issue you will find many people with the same complaint about this transmission and hopefully the fix.

I have a tko600 in one of my cars and all you will need is that short throw shifter. I got mine from steeda. I use automatic transmission fluid. The spigot bearing i made an adapter and run a roller bearing. I'm using a sprung button clutch and 3000lb presure plate. 7200rpm shifts easy. A mate of mine also uses a tko600 in a dedicated track car 670hp 620torque had the same problem kept on missing 3rd. Put a short throw shifter in fixed. It's money well spent

Transmission: There is a kit to fix the 3rd gear problem. I installed one last year. No big deal if you have taken manual transmissions apart before. You get a shift rod, carbon fiber blocker rings and some other small parts that I don't remember. Call Liberty and they can hook you up. http://www.libertysgears.com/index.htm

I;ve been thru all this before and then some... All I can say is if you really want to run this tranny with overdrive (like I do), and you are going to be racing it at the track occasionally, "Liberty" is the answer.
This is exactly what I ran into, and this is a post from someone at Tremec about the tko600 that I found on the computer. Not sure who< but this is the statement: "Moving on... Shifting a TKO aggressively (like most manual transmissions) requires you to do and know a few things. For starters, keep in mind that the single cone synchronizer in a TKO is only good to about 6,500 RPM. Any higher than that, and you're likely to experience a block out condition, or in other words, you will exceed the synchro's capacity and it will not go into gear without extraordinary effort. Second, clutch release is of critical importance. If the clutch is not fully disengaged at the point when you attempt to complete the shift, the synchronizers will have to contend with all the rotating inertia of the engine in front of them, instead of just the mass of the speed gears they were designed for. So if your timing is not right the best case scenario is that the trans will not make the shift and the worst case is that you will severely damage synchros trying. Lastly, as equipped from TREMEC, the TKO has a self-centering shifter that lines you up with the 3-4 'gate'. Do not try to 'steer' the shifter by gripping it and slamming it around. Rather you want to let the trans do some of the work. So when performing a 2-3 shift, just put your palm against the back of the shift ball and shove it straigt forward--the trans will take care of the rest.
Normally in a case such as yours, I strongly recommend that you play around with the trans, first at rest, and then at graduating RPM's. Get a feel for how your TKO likes to be shifted and slowly add revs as you feel comfortable. Until you feel confident, I would surely recommend lifting between shifts. However as you get better and better you'll eventually be "power-shifting" like a pro--foot on the gas and kicking... well, you get the idea! Just remember the harder you are on your trans, the faster it will wear, period. Additionally, if you screw up badly in the heat of battle, you run the risk of really causing some carnage inside the trans. But hey that's all part of the game my friend, and what seperates people like us from those girly-men who would rather let a valve-body do the work for them(LOL)!"
There you have it from the source. If you want to powershift or shift at higher rpms, modification is the only answer. I had mine "Faceplated", but there is also "Pro shifted" mods.

Good luck.

Thank you very very much Chargerfan68. That info you posted was exactly what I, too, was looking for. I´ve got a TKO600 with all the "big kit" stuff from Keisler (pedals, driveshaft, clutch, floor hump etc.). How do I know if I have a "standard" shifter ie. not the optimal 3-4 gate centering one? My trans is still on the shelve here, not installed in the car, yet. Thanks for info!

I think, by design, all tko600 trannys are self centered 3-4 shift. The 3/4 gear are the center rail and the outside gates are spring loaded to push the shifter to the center rail.
Just wanted to add that when I did the Liberty mods, the synchro cones were still in really great shape and still gripped the gear. Also, I had 51 track runs before the mod hitting 10.97 with the stock tranny. Just the 3rd gear was hit or miss at 6000-6600 rpm shifts and felt exactly like they stated..." A block out condition". Like i was hitting a wall when trying to shift it into 3rd.
Hope this helps.
