Jack -

I never noticed that much lugging in those GM cars in ordinary daily driving. A Monte with a THM 350C exhibited some bucking that was due to a failing TCC solenoid, but the engine continued to give many miles of trouble-free service after replacing that.

I have to wonder if the situation with SBC bearings was more of a coincidence with the presence of a lock-up converter, yet rooted in some change in bearing material or supplier. Of course, I'm no master motor builder, either, but seem to have noticed a progression toward marginal materials and engineering with GM product over the last 30 years.

When it comes to Packard, the very first Ultramatic that was introduced in 1949 had a Direct Drive (lock-up) clutch in the converter. Yet, we don't seem to have a problem of premature bearing failure in those cars.
