But if it remained in a lower gear-it should accelerate- According to the OP-it jumps up to 3500 RPMs right away but the speed REMAINS at 55 mph so the RPMs double-speed stays the same power RPMs are being made at the crank-but it sure isn't getting to the driveshaft Eve if it IMMEDIATELY downshifted 2 gears-it wouldn't explain the no acceleration-since even at 3500 RPMs he has 2000 MORE RPMS on tap?? Why the heck don't the RPMs KEEP going up?? OP do you FEEL hear a downshift or two?? Strange it doesn't increase RPMS- why "stuck at 3500 rpms and 55 mph?? If nothing is slipping what gear gives 55 and 3500- 2nd gear?? Maybe it is a strange fuel flow problem?? Enough fuel flow to do 3500 RPMS and 55 mph in second gear or 3000 RPMS and 100 mph in 4th Maybe it is fuel flow STRANGE?? If it was slipping-should slip all the way to the rev limiter or to 6000 RPMs if no limiter-guess probably no limiter on a 1995- so probably not slipping-maybe fuel flow??
