Does it have the 3.4?
I've seen SEVERAL late model trannies mated to the 3.4 basically SHEAR the teeth off of the planetary gears. Not pretty.
Seen it happen on a Monte Carlo 3.4, Impala 3.4, Buick Rendezvous 3.4 and another 3.4 car just last week. All cars were late model '97-'02.
Interestingly, I haven't seen this happen to one mated to a 3.8 n/a or s/c.
