The car has an automatic trans. And about 107K miles and has been maintained religiously. The problem started while driving 70MPH on the highway. There was an abrupt pause in the forward motion, lasting about 1/10 of a second. The speed slowed only slightly and resumed (using cruise control). I kept driving as normal (60 mi. to work with 45 remaining) The transmission operated normally as far as upshift and downshift. After arriving at work, I found that I had no reverse, so I drove forward into a parking spot. I had a truck and car trailer delivered later to tow it home and found that I had no forward gears. The front wheels were also locked, in forward, reverse, and neutral while the car was running. After shutting the car off and letting it sit for 20 min. (pondering what to do...), I rocked the car and found that it rolled in neutral. Loaded it and towed home.
Codes PO700, PO715, and PO720 have been set. The fluid has been drained (long-time Amsoil user), all was crystal clear and absolutely NO debris or discoloration. I removed the final drive cover and all looks good as far as the differential operation, gears, and bearings.
I would think this would be a hard-part failure, but have more experience with non-elec. RWD transmissions. I am rather savvy and have my own shop with lift and normal equipment.
Any thoughts would be appreciated.
