I think I lost the torque convertor lock up, when I drive about 70mph my rpm are about 2200rpms what is your rpms when your on freeway cruising? I think it should be below 2000Rpms right? Thanks.

 

With a 3.42 rear axle, my rpm at 65mph is 2000.

 

Depends on what gears and size of tires you have. Put up what you currently have and I'm sure someone else on here will have the same setup and can give you a comparison.

 

with a 3.73 I think 70mph is near 2200rpm

 

cool thanks guys I guess I'm ok then, before I was having trouble with the torque convertor locking up because of the valve body issue, so I took out about a qaurt of tranny fluid and dumped in a bottle of lucas tranny stuff and it seems to have fixed it because before on the freeway the rpms woud jump around, never knew what were normal rpms for it on the freeway.
