Thanks for reminding me, Tim.

Note to self... MAKE SURE HUBS & RING GEAR ARE TRUE.

I was actually thinking that I'll get the machinist to bolt that hub back onto the output shaft and put the shaft in the lathe chuck to double-check the work. (He can lop the shaft off where needed to fit - it's being sacrificed to get the 2nd gearset off it anyway.)

EDIT: Hey - perhaps I should bring it to machinist friend #1 for quality control....

Second opinion never hurts, unless it bothers 1st opinion's ego... but then, if that's the case, you probably don't want that guy's fingers in your parts anyway.

Tomorrow I should have the answer to the key question: how much does the machinist want to do this job?

Some useful although sometimes confusing transmission codes for the Metro

Keep in mind that there are US/Japanese/other destination models for the many badges and years of the Metro or Metro related cars so there is no set rule like all 4cyl 5speeds in 1999 were final drive ratios of 3.95:1 (<-------I didn't make this example accurate)

From what I've been told and briefly read there are at least six final drive ratios ranging from 3.52, 3.61 (Automatic), 3.79, 3.95, 4.10 (Automatic) and the 4.39:1

The lower the number the taller the gear. The teeth for the tallest gear (preferred for economy and not a good hill climber) counts 72 and the shorter gear (preferred for fast acceleration with higher rpms) has 79 teeth but I haven't verified this tooth count to be absolute, it's basically true but this is an unorganized and impromptu post and has obvious holes in it. I think the 3.95 is the 79 tooth but don't know the tooth count of the 5th gear for the 4.39 FD so any research on your part would be greatly appreciated and I would gladly edit my post to make it more accurate.


I would like to see a data base of:

Make....Model....Year....Engine...Manual/Auto...F. D. Ratio....GVWR....Tire Size

for the Geo Metro. With this information we could pick our transmissions from junk yards much faster, cross reference parts, and be overall better informed. The 3.52 fd ratio is not from the XFi which has a 3.79:1 ratio; it's from another model the 1989-94 SOHC 1.3L Swift hatchbacks and maybe others.

I hope this helps.

What do you think about a data base for Geo's? - Dale

I'll be willing to check mine out, I'm pretty sure when I get them, I'll have to pull the transmission apart and replace 2nd gear... guy says it won't go in at all.

Supposedly, I'm picking them up this weekend, so we'll see what happens.

Hell, I'd even go further and propose a big wiki here with all the info you mentioned plus cd/cda, avg. CL & ebay used prices, and curb weight for ALL cars of interest to people like us. I'd be happy to save someone the trouble (not really trouble, I kind of enjoyed it) of hunting down those numbers for use when choosing a base for an EV conversion. There's always the ideal base, but then there's what comes up near you on CL. Let me know when this wiki is made and I'll start punching things in. chop chop, beloved mods

I think you have rights to make a new wiki page: Main Page - EcoModder

Search for the topic, and if none exists, you're presented with an option to create a new page on that topic.

Knock yourself out! Let me know if it doesn't work.

Well, I'm not an NHRA dude, but just (finally) got an estimate of ~$200 for the job. I was surprised.

(EDIT: the guy is a customer of my brother's, and my brother said he gave him a good deal on some work, so this is probably returning the favour.)

So it is going ahead. At this pace, I expect to have a the new gearset in hand next summer.
