    Having transmission problems on four M Business Class straight trucks.
    The transmissions are the MBT660-60a (Mercedes Auto) 6 spd automatics.
    All four trannies would slip out of gear to nuetral and would not re-engage to a lower gear or any gear.
    This is really odd since it happened to four trucks within a week of each other.

    After repairs were made by Frieghtliner, all four trucks developed other transmission problems ranging from computer failure to bearing freeze.

    I would be interested in hearing from other owners of trucks with these types of problems with this transmission.

    Thanks

    I am experiencing a recurring problem.
    The inner wheel seals on steer tires are failing contaminating the brakes and requiring new seal and new brake job. It's happened twice in a year. I replaced the right seal along with new brakes to the right side in the spring. 5 months later it's leaking again.
    So I replaced the hub assembly which includes bearing and race and new seals this time on the right steer today. Now I noticed the
    other side is leaking and has contaminated the brake shoes again. Guess I need to replace the hub on the left side as well.
    Hub assembly is only $250. Plus install. I'm thinking it's not a bad idea to put new bearing on an axle that has been driven over a million miles.
    It's a 2001 century.
    All inputs are appreciated.
