Got the level 2 4l60e. Put about 2k miles on it so far, behind a 500whp ls1. So far I'm very impressed. Shifts SIGNIFICANTLY faster and firmer than before. Holds my power level well. I also ran a tru cool 40k cooler, so I'm confident I won't have any issues in the future. Customer service is great, very helpful on every phone call. I'd recommend these people to anyone especially a 4l60.

Alan, Ryan and Frank plus the rest of the team are simply hands down the best. I have level 3 4l60e that is amazing behind my 2005 turbo gto. Their customer service is off the charts!!! I highly recommend them if you are looking for a 4l60e that will stand up to power.

I bought a trans from them and I have had some very small issues but Ryan has been just great at helping me resolve the problem and I know that I have bought one of the best transmission on the market.I do not think you can find a better group of guys. I also like that he has a very large videos on You tube and I have learned a lot. he also has something that I have not seen . if later down the road you need a rebuild of his trans they will do it for a cut down price not the full price like some people . nobody does that. GREAT JOB GUYS !

Ran their level 3 700r4 in my nova for years, this was the only shop that could build one to last street and track abuse. Never had an issue, service is also second time none. Will not find a better shop for your gm transmission needs!
