TKO 600 Problem

[Ant]

I think most transmissions can have problems, I have used Toploaders, Muncies, Seanz race transmissions and my current new Jerico five speed!

The Muncie was fantastic, and faster changing than the Toploader, and the Toploader can have baulking problems but some of that can be attributed to worn linkages etc.

I read a post (Coyled) mentioning the TKO has parts in it made of pot material, well when you read the many problems with the old Tremec 3550 etc, and now the 600 blowing its guts on race tracks, why would you buy a mass produced peice of rubbish, and they even call one version a "Road Race" ...........??? even if you put the trans behind a 100bhp engine it would probably still have shift problems. It is evident from road racers who now have realised either a nice Toploader, or G-force, Jerico purpose built transmissions are better ways to go. I considered a TKO 600RR Transmission and I am pleased I purchased the Jerico. I guess for road use the Tremecs are okay if you dont beat on them!

All these problems just for the extra fifth gear, and they apparently copied off the Toploader in some of the design, well they certainly fudged that up, having said all that I recommend for street and part time racers the T56, which can be had from several suppliers with different gear sets and triple cone syncros even 22 helix semi straight cut gearsets, the downfalls are the weight/$$$$$, plus used with a ridiculously heavy Lakewood bellhousing and you have about 175lbs of transmission, but thats okay in a big block grunter, my cars total weight of transmission and bellhousing is 100Ibs. G-force make a nice race T56 that can handle 900bhp, and other suppliers 650bhp versions, and they shift nicer than the 600.
