Transmission problem
1993 GMC C2500 V8 Two Wheel Drive Automatic 230000 miles

the truck doesn't want to shift after it warms up or it shifts hard like a shift kit does. I did replace the 1-2 shift solenoid two which work for two days and started back up again with the same problem !
What do I need to do? Or replace other solenoids? I need your help

It sounds like your accumulator piston spring is broke. It is located under the valve body of the transmission. This is the spring that takes all the hydraulic shock when your transmission shifts. The stiffness of this spring regulates the firmness of the shifting.
