You should know about this company. They send you a "warranty" and force you to sign it and return it within one week. If there is a problem you pay for everything except maybe repairs in their shop. And that is at their "sole discretion" and " absolutely no refunds". If you take it somewhere else you void the warranty no matter who's at fault. You pay shipping both ways, well over $600 in my case. If you are alright with this go ahead. First time out, no third or fourth gears, there are score marks on the outside of the servo like someone forced it with a pipe wrench. I don't know if this is related. They say all transmissions are "thoroughly tested" but there wasn't residual fluid so I don't get how the pumps, valves, etc could have been shown to work with out filling it up. I don't work on AT internals but I've installed a few successfully and there weren't any issues on my end. One more thing, no big deal just sloppy, the bell housing doesn't have the right female threaded holes to fit my torque converter cover. I'm a working guy, out 1200-**** bucks and a lot of work, spending $600 more and weeks of downtime on my truck doesn't seem worth the risk. I bought a transmission elsewhere, works great, so I'm positive the problem was theirs.
