Thanks, Robyn. Any simple checks that I can do, from underneath? I'll get under an check for loose wires, etc, as well as call US Shift.
If nothing obvious appears, I'll probably take it over to Bill, the guy who R&R'd it, for taking it to the trans shop in Show Low and back. BTW, that shop's claim to fame is, that he replaces all the electronics in the gearbox. That's (supposed) to be why it cost me over 3 grand!
Question. Given what I've told you about it, what are your thoughts on towing it in neutral for the ~8 miles, over to Bills? I was already thinking that I'd disconnect the driveshaft, but, if it's not necessary - - - ?
