Have 93 6 lug K2500 that usually runs pretty smooth.
Current issue came after changing out the radiator and oil cooler lines the transmission wouldn't shift into 3-4 (D-OD). Found a leaking transmission cooler line and replaced it. Still has the same problem. Fluid is good and doesnt smell burned.
Think the A/B solenoid went out. 1-2 are good. ???
If I give a lot of gas it'll rev and shift at about 4k RPM into 3rd and 4th. Downshifts when slowing back down.
Thanks
Rob
