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?
you lost over dive, aka the 4 th gear hub.
if you get in the hwy and pull it into 3 rd and the rpms stay the same, you just confirmed it.
If it shifts into every gear and does change rpm when you pull it back down into 3rd, something else is way wrong.
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.
