My 1996 Chevy Suburban will not run in overdrive. What would cause that. on 1996 Chevrolet Suburban 2500

It will run in 3 but it seems to stuggle. If you start out in overdrive it goes through the gears until it is ready to shift into Overdrive and then just doesn't!

I had the same problem. Transmission had to be rebuilt.
