TKO 600 ....Anyone done one?

Hey Kev, I used the Keisler TKO in my car. What Keisler does to the transmission is cut a chunk out of the front top portion of the TKO so that it will fit around the crossmember, then they put a new cover over the cut out. I have heard of the TKO's locking people out of gear, but i think that was with some of the first ones that come out. There is also a pretty precise bell housing run out you are supposed to have, that may have been some of the shifting problems in the past. I use mine on the street and the drag strip. So far it takes the abuse that my 408 can put out shifting at 6000 rpm. As far as the viper 6 speed goes, you have to put in a new transmission tunnel and build a new crossmember for it to fit. I am not sure how they get the shifter in the right place though. There are some pretty good builds on here that shows the process some of these guys have gone through to put the 6 speed in.
