1996 GMC Sierra K2500

Asked by JasonK7 Jun 06, 2020 at 03:51 PM about the 1996 GMC Sierra C/K 2500

Question type: Maintenance & Repair

Was driving my 1996 GMC K2500 pickup yesterday. In a
blink of an eye I felt gear loss, RPMs spiked to redline.
Shifting from gear to park im having a grinding noise.
Played with my gears a bit when I was safe and found I do
get gears when in 4l, 1st and 2nd in 4h and nothing in 2h.
Tow truck dropped it off this morning and I started playing
a little bit again. I now have gear connection in 2h and the
truck will move on its own power when letting off the
brake. Grinding is still present going from gear to park.
Tranny fluid is good and it was rebuilt 30k miles ago. Im
thinking tcase. My ASE certified buddy thinks tcase from
what i told him as well as my brother in law. A family friend
after playing with it himself is thinking tranny.
Anythoughts, ideas or any experiences like this?
