yea 5th isnt .068 its either .68 or .82 i belive.

....for the 'gear ratio', I took my 5th gear ratio (.68:1) x my 'suspected' rear end gear ratio (3.73). Or like you said (.68x3.73).

OR (I would think)

You could just check your RPM's in 4th (I would think) which should be 1:1 (I think all T-5'd were 1:1 in 4th). That would give you what your RPM shoud be in 4th gear at a particular speed.

I think factory for most years was 2.73, and 3.08. If your close to those numbers your probably 'stock'.

I was shocked when I ran my numbers.......... ;-) Someone beat me to the Gear Change!

5th should actually be 1:1 but .82 would be about right.

tcwc

4th should be 1:1..... (in my opinion). 5th should be .63 or .65. (OVERDRIVE)

Just my opinion.... don't get PO'ed at me! ;-)

You are right. 5th is overdrive in a stocker. Sorry used to changing clusters to make a 5 speed keep up with a six speed. I was never concerned with mileage. But gas is almost $3 a gallon, wow! I may be in the geo metro biz before long. LOL!

yeha i rotated the tire and watched the driveshaft i definatly went over 3.5 turns so i guess its eather 3.55 gears or 3.75...i hope its 3.73

Goosepoop302

ok i jsut did it with my dads help. it spun 3 times full around adn just about exaclt another 3/4 turn.....good news?

splitting hairs between 3.55 and 3.73s unless your are at the drag strip. You can kinda eyball the tenths or line a chalk mark on the diff lining up to the drive shaft. Then you get a reference point for halfway, 3/4 around.

Next time you change your rear diff oil. Look at the pinion gear most company's put what gear they are. or you can divide the # of teeth on the pinion gear into the # of teeth on the ring gear. for example if you have 10 teeth on your pinion and 41 teeth on your ring you have 4.10's
