LOL I hear ya. Ask any off-roader who uses "granny low". They can back my "backwards" terminology.
Lower gears have bigger ratio numbers. Backwards as it seems, that is the way the rest of the world sees it too. It's not just me being silly.
Anywho, to the OP, I would do the trick someone already mentioned and count tire revs vs driveshaft revs to determine final drive ratio and go from there. I doubt there is a combo of transmissions and rear ratios that would account for your numbers being so out of whack, but determining your ratio is a good start.

there is a difference in the sequence of the gears of the transmission and the final drive ratio.
everyone i know refers to the final drive ratio being "higher" or "lower" based on what's happening with the INPUT to the diff, not the output to the wheels.
see what i mean?

jesus chrysler, i figured you would pull the only hit on google that explained it the backwards way.
also, excerpt from that site, which looks like a middle schooler created it:
"I don't how high ended up meaning low numerically or low ended up meaning high numerically, but they do. "
(no they don't)

Well about the tach I gotta check cuz the owner who had it before me did say that he changed it but he didn't say if he changed it for a SC400 tach I gotta check that out. So then my car acting like this has nothing to do with having an auto ecu & the O/D light flashing on/off?

Yea I gotta find a SC300 cluster to make sure. BTW could it be 1 of the speed sensors cuz I had a guy tell me that they come with 2 speed sensors & that maybe 1 of them went bad?
