Transmission shifting up and down erratically

(1991 Chevrolet C1500)
When I am driving down the road anywhere above 20 mph, the transmission starts shifting up and down, and some times seems to lock in a higher gear and won't down shift.

Sounds like maybe a torque converter clutch, unfortunately the transmissions gotta come out to replace the torque converter
