I have 1999 Chevy S-10, 2.2L, 151,000 miles with automatic transmission.
I had a transmission service and several leaks were fixed at my local mechanic. Since then, it downshifts around 70 mph (rpm goes from 2750 to 3500 and back and forth). There is no load on motor, it happens going downhill as long as constant pressure is on the accelerator. When I back off, it drops back to 2750, but will jump again when depressed.
Fluid level is fine. Any ideas?
have the same problem?
