No Backum Up Gear


Recommended Posts

Last Monday our Volvo 770 Autoshift decided it was not going to function properly. Would not stay in reverse. Would go in, show me a bunch of arrows on the gear selector, and then maybe engage...or not. By the end of the day, it would not engage at all. Forward works fine, upshift / downshift work fine, just no reverse. Whipping around town trying to find a campground knowing you can't back out does bring the focus level up a few notches.


Because of my history with this truck, I was fairly confident that the issue was most likely some sort of sensor issue. That said, it could have just as easily been the syncro set. Point was, I was not likely to be able to diagnose it myself laying on a bed of nasty sharp little rocks in 95 degree heat.


So down the road to the Volvo dealer - 4 miles. 2 shop shifts later, they determined that the switch, plug, and small wiring harness that control the reverse circuit could not be repaired in the shop - plug and pins just to worn out. Sssooooooo....they have asked for permission to replace all those parts. About 6 hours labor, plus a little time for diagnostics. Wow.....


We used to have a saying that if you weren't having enough fun, you weren't spending enough money. Near as I can tell, so far on this trip we ought to be drowning in fun...

P.S. There isn't really any way to PM this thing, or to do anything other than wait for it to give out.

Wow! Paul and Bill and I have the twin trucks!!!! I guess I'd better get ready!!!!!!!

Of course I don't have a trailer to back into for hitching now (got towed away yesterday), but I may need to back the truck somewhere, sometime!

Shouldn't that be triplet trucks??
