I recently purchased a 1995 gmc sierra 1500 that had weak reverse gear. Now when I am in overdrive it will not shift from 1st to 2nd gear and it cuts out when I get to about 55mph. Overdrive works well at low speeds. Could this be a fuse issue or do I need to pull tranny and rebuild it?
Thank You.

Rebuild gearbox bruv its knackered
SOURCE: no overdrive or 3rd gear
transmission needs sunshell and sprag update internal repair needed
SOURCE: 91 gmc shifts in and out of overdive
I had an 89 Suburban that started doing the same thing. Change the fluid/filter and add a quart of Lucas Transmission Fix. See how that does. Ultimately, you are going to have to rebuild or replace the transmission as the problem will only get worse in the end. Mine finally went down completely and cost me about $2700 to rebuild.

The filter has nothing to do with your issues.
Check for a loose or misadjusted brake switch, for the OD issues.
Maybe Electronic,Sensors or Selenoids,on the shift issues.
