I bought at TC and VB kit from TST back in Jan. of 2000. The TC was a Dunrite and the VB kit was a Trans Go. The TC had a terrible lag even with 4. 10 rears and running a #5 plate. After I added 370s lag lessened considerably. I thought it had disappeared, but now I know what absolutely no lag is with my new transmission. If TST is still selling Dunrites and Dunrite is still making the TCs the same way that they did 2 1/2 years ago, I would consider someone else's TC. To Dunrite's credit, the TC held up very well, the rest of the trans got toasted. I now have a full meal transmission from one of the big 3 transmission vendors on the TDR.
