1996 Other GMC Models V8 Four Wheel Drive Automatic 89000 miles
The Suburban transmission seems strong and very tight.
It shift gears like it is supposed to no slop at all.
However when driving at about 10 mph it makes a terrible grind noise.
It is the same noise that is typical when you inadvertantly shift too park while the transmission is still. It seems like the parking gear is trying to engage on its own.
On one occaission it jumped out of park into reverse.
