OOPSY, mine runs about 3500. That is pretty much more than 2500, I take it, that ain't good?

im not for sure i think they all run different

Yea, I think so too, at least I hope so.

me too

Ill cruise around 1000-2500 rpms on the interstate. depends whats going on in my car

cruise (ie maintaining speed) at 72 should be around 1900 rpm for a series II, not sure about your series though.

RPM is dictated by the transmission gearing ratio. We need the RPO code of your SSE to properly determine what gearing. In my 89 70 mph (115 kph or so) it was about 1800-2000 in OD.

However in my high geared Aurora its nearing 2500.

I have series 1. Where do I find the RPO code?

Look on the top of your spare tire cover in the trunk. You should see a sticker with a bunch codes on it. They dont say which is which so right em all down and post em and we can find your gearing.

ok there were a whole bunch of stuff so here it is:

AAA, A24, PF4, C97, D55, VH9, ME9, NA5, 15I, US7, ZU1, B18, Y85, AU1, FE2, AL7, PB4, YGW, MXO, 15D, 159, UX1, B51, 848, Y98, 828, FCT, R6U, IFD, UK3, VQ6, T82, V73, 4OU, VO8, 92C, B53, 7HN, C68, GX3, CD2, LN3, R92, JM4, UQ1, VX5, V41, WEN, 6HN, 82C, B57, CE4, K68.


I don't know what it all means but I think I have a BINGO in there somewhere. I hope I got them right. I appreciate your help.
