Oh yah, if the truck sits for a few days and its cold it has a couple second delay into reverse, but if you give it a rev and then shift in reverse its fine. Done that ever since i got the truck. The tranny never slips though.
4wd "K case" TH400
Has a 6 bolt torque converter.
8 bolt pattern NP205
I travel to so cal ocasionally, It will be a few months but i travel to pismo and the hammers (johnson valley).
Will ship on your dime.
It would be cheaper, but the nearest foreward air terminal is in San Francisco, so i'd have to charge ya to crate it, and drive up there to drop it off.
