Problem with companies that rely on warranties, especially when you are doing the work... you dont want to have to use them. The companies that do the rebuilds for the parts store chains, dont have a strong reputation in the repair industry. Why? Because we dont like redoing work because of shortcuts and sloppy workmanship at the rebuilder's end. You end up with a pissed off customer, and in our case, we might get some labor reimbursement, but it rarely covers what we have invested. Via Jasper, which has a stronger reputation, but not as strong as an OE reman unit, $3400 bucks plus the install kit, which I strongly recommend, etc. Strong warranty nationwide. Not doubting your skills, but Ive worked with, and trained ex-GIs who worked on tanks, choppers, aircraft, etc, and some were good, alot were bad. I'm decent at what I do, but I wouldnt go tinkering on an elevator, unless I slept at a Holiday Inn Express last night,lol. If you've never done it, get a friend, preferably one with some experience, to chip in and help.
