The 700 is a good trans when properly built and adjusted. If not, expect to replace them frequently. 3K is way too much, and that GM trans, though it has a warantee, is not a HD version- just a stock replacement. If you are hard on your vehicle, tow, or have more than stock HP, you'll be far better off with an aftermarket trans. For 3K, I'd want a level 3 BTO 700R4 in my vehicle, or a 4L80E swap. Screw the dealer.
