I had my 4L60e rebuilt by them, even after they supposedly run it on a dyno, the thing still doesn't shift right. It does work now, as it wouldn't move the truck before, but something internally is either sticking, or they missed something, as it doesn't like to downshift into 1st gear when coming to a stoplight. You have to get on the gas a second or two, you feel it lug abit, then it drops into 1st and takes off.
That is the only real problem i have with it.
They were also a couple of days longer than they told me for therebuild, which put a real damper on things around the house for transportation.
Nice and cheap for a vehicle to get it running if you are selling it or trading it in (if you're that type of person) but i personally won't go back there for quality work.
