TCI heavy duty 904 rebuild kit will make tranny handle 550 hp

Once it leaves your shop, you can't be sure that the customer makes sure that the fluid level is maintained. Even without paperwork, I stand behind my builds. Sometimes a customer runs it low or doesn't hook up their kickdown, then I charge for the repair. While I get trans work from hundreds of miles away sometimes; I prefer it be close by. If you order a heavy bulky item online and shipping it is expensive, I would think a warranty would be about worthless. I've repaired several TCI transmission that were still under warranty because it was cheaper to fix them than to ship. TCI is picky about their warranty. There's no "fix it no matter what" with them. For instance; if you break the pump installing it, they won't work on it at all for any amount of money. When people ask me about a warranty, I say, "If I screwed it up the first time, why would you want me working on your transmission again?"
