Thread: Revving high at 55 60 mph

I have a 2002 gp gt 4 door, when at 60mph I'm revving about 2k and on hwy about 2500, anyone know what it might be?

if you get in the hwy and pull it into 3 rd and the rpms stay the same, you just confirmed it.

I shift into 4th tho so can it b that?

Like internal transmission failure, major slipping or something.

The most likely cause was said, if the 4th gear hub is gone. RPM at 60mph in 4th gear should not be 2500rpm, should be 500-600 less than that.

Is 2k at 60 2500 at 70 I feel 2k is high for 60 as ive been getting horrible mpg

I third that. It's your 4th gear. Sucks to get to, but if you want to be cheap, you can access it through the wheel well with subframe dropped. I really do not recommend this due to 1) contamination and 2) if you're doing that much work, might as well rebuild your transmission while you're there. It's really not that bad. Just did mine.

It's the 4th hub. Search on my name and 4th hub shaft or something like that. It's not a horrible fix.
