Default Is this normal

I have a 95 auto and it cruises at 80mph right around 2000rpm. That seems a little low to me. Anybody? :confused:

You've just got the taller gear set, 2.73 to 1 if I'm not mistaken for that year in convertible. Scorp know's, he'll probably chime in later today.

You've also got the 4L60E which has an over drive of 0.70, and the lock-up converter decreases the cruising rpms by 300-500 rpms.

All this stuff put together gets you a really low cruising rev. :cheers:

I would bet 2.59's since mine does 70 @ 2000rpm.

Now that I think about it, I turn 1800 rpms at 65 mph, so at 80, that should be around 2000-2100, although I've never thought to check.

I have a 2.59 rear gear.

Yes, it is completely normal. This is one reason why late model Corvettes get nearly 30 Mpg on the highway.
