Transmission problem
1994 GMC Truck V8 Four Wheel Drive Automatic 216000 miles

When I drive up a hill or need to downshift to accelerate my truck runs rough the tach jumps around 2,000rpm and makes a bogging sound, I think it might be slipping but am not sure, I would rather try some other things before I drop a couple hundred on a rebuild, thanks

Do you
