Alright, here's the verdict... I can only get it to "click" or shift into 3 different positions. Is that normal for a 5 speed? When the shifter is all the way in, the input shaft rotates around 3.4 turns while the output makes one full rotation. When it's in the middle position, same results...3.4 turns. When it's all the way out, it rotates about 4.8 times. What do you guys make of all this? Am I missing something?

If it was 3.2 that you saw, then you have a 4.10 trans.
If it were a 3.52, then you would see about 2.8 with a .8 fifth gear.
Maybe I didn't see it right then, becuase if this were a 4.10 trans you won't even move the Metro with a 3.52. My trans came from a '94 SOHC 1.3L Suzuki Swift. See the chart, I have the same tires also.

Ok, so I think I got it. Since my tranny's crown wheel has 72 teeth, it should be a 3.79 tranny. Woodie stated in a diff. post the gears & ratio:

1st 3.42
2nd 1.89
3rd 1.28
4th 0.91
5th 0.76
Rev 3.27

Final drive 3.79

If this info is correct, 3rd gear is 1.28*3.79=4.85 rotations (what I estimated, but wasn't sure what gear). 4th gear is .91*3.79=3.44 rotations (what I estimated, but wasn't sure what gear). The only question I have is why then does the pinion on have 18 teeth & not 19? 72/19=3.79 Everything is adding up, besides the 18 pinion teeth.

I will be very interested in how your car performs with that 3.79 and compared to mine. Report back when you get it in and running. It will be interesting your rpm at 50 mph as compared to the chart I posted. You running a scangage?

But, I also have a 1993 Metro.
When I first put the transmission in, it was great! I was easily achieving high 50s and low 60s. Bets tank - 69.8mpg.
I still had 155R12 tires.
Later I went to the 13 inch tires because 12s are getting harder to find.
I also went with 175/70R13, a wider tire. Trying to make the ride a little softer.
The ride is much better now, but the gearing is too tall and I work hard for a 55mpg tank.
This is exactly what I'm trying to say. Changing one wheel/tire size basically changes one gear ratio step. metroschultz went past the sweet spot and experienced a drop in mileage, and remember, his car is substantially lighter than yours.

Yeah, I'm very tempted to keep the 3.79 with the varying experiences being reported. I'm currently running 155/80R/13's and don't plan to switch. That's what Darin is running on his Firefly, so I figured I could get away with the 3.52 as well. Woodie is right, I think 175's are just too wide... It'd be interesting to see if he went to 155's. If you all remember correctly, Darin actually put the 3.52 into his Firefly 1 year BEFORE the XFi cam & reported that he loved it?! So I suppose everyone's opinion is going to vary. I won't have time to get the "new" tranny in until this summer, but I will certainly report back.

I have been known to do that now that I have larger tires.
If I am cruising the highway @ or below 55.
Above 55 I use 5th.
I also have an Xfi cam and 6* cam gear. These allow me to run around in 5th all day long if I so chose. At 1000 rpm, in 5th, I travel at the brisk pace of 28 miles an hour. Perfect for putting around town.

Well, it looks like I'm going to stick with this 3.79 tranny. The junkyard I bought it from sold the 2nd 3.52 so I can't even have them verify the teeth on the crown wheel. I suppose I could take it back & continue my search for a real 3.52, but from the sounds of it, I think I'll be pretty happy with the 3.79 & will still see a pretty good difference seeing as how I'll be on 155/80R/13's.

Whoa there Nellie! I think you misunderstood me. When I said changing the wheel size changes the gear ratio, I meant DIAMETER, tire width has nothing to do with gear ratio and will make very little difference as far as gas mileage or acceleration is concerned. I think 175's are a good minimum tire size, but I'm more interested in tires that actually grip the pavement than I am in ultimate fuel economy. I have 195/50-15s on my car and keep a set of 185/60-14's for bad weather. Didn't notice any measurable mileage change when I went to them.

I agree.
the 175 is a good minimum size.
The 155's are too narrow.
