You shouldn't be able to kick down to 2nd at 80.

even with 2.84? It can be soooo slow if it doesnt...I am thinking about taking the dash panel off, and seeing if I can turn the needle down some, and do trial and error until it shifts at 5600. I hope that works. Or should I get it scanned first by a scantool to make sure it isnt about 5600?

You can't 'fix' the tach. Don't mess with it. Get a scantool on there and find out what'* going on first. There was a topic not long ago about a couple other cars with this issue.

I am agreement with wilren get scan tool read let it read some of data. My Bville idles between 700- 1000 it really just depends how cold it is. Those number for those speed vs rpmdont seem way off although shift at 6000 rpm is not right.

I agree that the tach probably shouldn't be tampered with, at least in the manner mentioned here. Looking at these RPM'* vs. MPH listed above, I am not too sure those are that far off. They may be about 200RPM higher than what my '93 SE runs, but no more than that. As far as the 6000RPM @ WOT, I can't comment on that. I rarely go above 3500RPM. I just don't get into the throttle that deep.

Did you try tapping the brake while holding @60 MPH or so? If the RPM jumps up when you do this, then the TCC is working.

Good Luck!

My tach is known to be off by 200rpm, temp is off by at least 5 degrees and the fuel gauge is the furthest from linear.

The gauges are merely a reference.

Yeah, I guess I'm not really worried about what the tach shows, I just want to make sure my trans and computer is alright. I also dont want to get horrible gas millage with a slipping trans and stuff. I need to find someone with an OBD1 scantool. I wonder if Autozone has one?

Don has one.
