2001 Chevrolet 1500 Truck – Automatic Transmission Jerks
My 2001 Chevy 1500 with an automatic transmission does fine until you get to 41 mph where it shifts to overdrive I guess. The RPM drop to 1100, when you speed up slowly to say 45, 46 mph it “bumps” real bad several times. I changed the fluid and filter 6 months ago at 50,000 but this has not helped. Do you have any advice?
