You have a 722.1 trans.

The reason I didn't describe the adjustment is that with the amount of miles you have the band is likely to be worn out or has been adjusted before. As the band wears out the adjustment gets touchy.

I have had it happen twice myself. If the band is too tight (easily accomplished on worn band) the thing self energizes like a set of brake shoes putting the car in two gears at once which locks it solid. It didn't hurt anything on the two I dealt with but it was a scary event and if done at higher speeds could have been disasterous.

Basically you tighten the band bolt to a torque and back it off a certain amount.

BTW the ATSG books are well worth the money. Better in many ways to MB info.
