GM and Allison Automatic Transmissions are extremely reliable and durable. Never had one go bad yet in my 61 years of using them and millions of miles of use. The 1984 Chevy Heavy Half pickup with the 6.2 diesel for example had 168,000 on it and was use to pull our boats and travel trailers when we sold it to the son of a Michigan State Police Officer close friends of ours.
He drove it until it had 497,000 miles on it pulling maintenance trailers back and forth across Michigan twice a week as he was the maintenance person for a 3 location apartment complex (1 on the West Michigan Lakeshore and 2 on the east side of the state - Pontiac and Bay City). It was totaled by being hit and crunched between vehicles from the rear of the dual axle enclosed trailer by a semi during a whiteout snow storm between Detroit and Bay City on the highway in a multi-vehicle pileup.
Still had the original engine and transmission in the truck, we know. 497,000 MILES!!! Just 3,000 short of half a million miles!
