Hi guys. I can't seem to catch a break. I've been putting some miles on my truck (03 GMC Envoy XL) again after a few past problems and while driving around 30-40 mph, I got on an entrance ramp onto the parkway and when I stepped on the accelerator, it felt like I was in neutral. I stepped harder on the gas and the RPMs went up but I was just coasting. I pulled to the side of the road and sure enough, I had no forward or reverse anymore. I could shift through all (RND321) and wasn't getting anything. I checked the fluid and it was full and did not look burnt (I just changed it recently). When I shift into Park, it still locks the truck in place so it doesn't roll.
I know when my transmission started to go on a previous car, I started to lose a gear here and there. Not the entire kit and kaboodle like I have now. I didn't hear any loud noises and no grinding. I've read about the fluid pump going bad. Please correct me if I'm wrong, but if I disconnect the transmission line from the radiator and start the engine, fluid should be pumping out. If it doesn't, that would be a indicator that it could be the pump. Correct? ...and in order to replace the pump, the transmission would need to be dropped.
Thanks for any help or suggestions.
