Any way to tell the final drive on the tranny itself? I may be entitled to a new tranny again here...

Back in the day when cars had drive shafts. you would mark the drive and rotate one revolution and count how many times a mark tire would spin. Hence 2.97 tire turns to 1 driveshaft revolution 2.97 to 1.

Every trans has an ID number on it ie part number match that number with the dealers invoice if a dealership done the transmission. A reman trans from a trans shop is stamp by the technician so it can be reference back their paper work on what type of trans they ordered. If it is your trans that was rebuilt you can check the part number on the trans or the RPO codes in the trunk.

So you can use the ID number stamped on it to determine the ratio? Because that'* what the shop did.

How many RPM'* are you running with the cruise set at an indicated 55mph on the HUD (with TCC lockup)? We may be able to do a quick comparison that way.

Wildman,
The final drive on your 2000 SSEi is 2.93
You have a 4th overdrive gear that is .705 for a final drive of 2.06

Hmmm.....let'* see...that'* 221 mph at 6000 rpm in 4th gear.

Thanks.

I should clarify, I'm asking about the '93.
