Earlier this year, I ordered a 700R4 for my K1500. Got it after the time period they said to expect it in, and since I was in a gnarly motorcycle crash before I got it, I had a professional shop install it and clean out the trans cooler system.
Their test drive went ok, as did mine, but as soon as I took it up a hill (while doing 55 in a 70 and not pushing it at all) it overheated and caught my truck on fire by puking more than a gallon of transmission fluid up and out of the dipstick tube and onto my exhaust manifold. Fluid levels were exactly right beforehand according to the dipstick that I ordered through them, and even if it was the wrong dipstick there's no way it could be more than a gallon off. I have played phone tag with them for a few weeks now and just finally was able to get an answer from them about this. Basically, despite their 'great' warranty program, I have to throw another 450 at them to have it shipped back to them and if they find a build problem, they'll fix it and reimburse me.
But according to every single review I've read of similar problems, there's no way in *** I'd get the money back because this company is unbelievably crooked. AVOID AT ALL COST. I dropped nearly $1500 on them for the excellent experience of watching my truck catch on fire, and that's about it.
Right after catching on fire and before being able to pull over, I heard loud banging and clunking from the trans meaning that something else broke inside, which of course they would want to bill me for. Do your research before wasting your money on this terrible service.
