Well, Dude, you seem to know yer stuph. 
  
I've got a Dummy of The Year Trick which I pulled a week ago. 
'91 Legacy auto/4wd 
I towed it about 140 miles with its back tires on a tow dolly (bad rear wheel bearing) and the front tires on the ground, trans in N, of course! 
Top speed 50 mph, yet the trip took nearly 4 hours. 
Now, I have only low gear forward no matter where the selector lever is located, no reverse, and when I decelerate, the tranny does not hold the car back. 
Got any suggestions as to what I may have damaged/screwed up (or should check) with my Dumb Human Trick?  (I knew better, and figured that low speeds wouldn't hurt.) 
Thanks, 
George
