Any 5 speed Transmission rebuilds with pictures available?

My '93 Geo Metro's transmission is making noises I don't like to hear...

Grinding, whirring, clicking, squealing sounds depending on the temp and God
knows what. The oil is a year old - Valvoline Durablend 80W-90.

Nothing hideous....just enough various noises to make me think it's days are numbered.

I suspect that the bearings are shot - the noises go away if I push the clutch pedal in.

Does anyone know of any threads on this forum showing how to rebuild the
Geo's 5 speed manual transmission - maybe with pictures?

I am fairly sure that one can buy rebuild kits - does anyone know of links to
places that sell such kits and their cost?

If you have rebuilt one of these little buggers, please contribute your experience
and help me and others out.

Two years ago, I did the Head and Rings. I am getting about 49 mpg.
She has about 230,000 miles on her (changed Speedometer for a Tach unit).

Now it is the transmission's turn for a face lift..

I can do the Clutch at the same time. I would take pictures like always...I promise!

After that, my Geo should be perfect.

Wish I could change my worn out parts for new and live forever.

I have a local Pull-n-Save that has (?) several 5 speed transmissions that I could
pick up for $65 - although someone told me that some numbers have to match.
Engine to Transmission matching....

Buying a used transmission - buying same problems?

Buy a remanufactured transmission for $500 (plus shipping)? - hmmmm.
A bit more than I want to invest - plus putting it in myself. Wow.

Perhaps. Thanks for the leads. I will have to think about that.

Since I did the Rings and had the Head rebuilt, I am just cocky enough now to
think I could do this myself....

Am I being too cocky?

If I do the Transmission myself, I will

1. Know that all is well inside.

2. Learn one Hell of a lot.

3. Be even more cocky than I am....

4. Can post more photos here and become infamous.

5. Cut my fingers, bruise my hands, learn new swear words, get greasy to the bone,
spend money, visit parts stores till I barf, discuss problems here....etc, etc, etc.

Actually - if I buy a used Transmission from the Pull-n-Save, I could then work on it
outside on a bench while I am still driving my working Metro, noises and all!

Gasoline in Spokane, WA just hit $4.04 per gallon.

I don't want my Metro to be down for very long.....Lord !

These Metro's are so economical that they may become something worth stealing now!

Doc, the recent thread by "Johnny Mullet" on the fourm explains how to pull the trans ( With pics). 1991 thru 1994 Metro Manual Trans removal process is identical to the 95-2000......But I suspect that if it's only making noises when you have the Clutch pushed in, a new Clutch kit would probably solve the problem since you'll be getting both new Pilot and throwout bearings with the kit. However, it does require that you pull the trans to put the clutch kit in. Here the link to Mullets Thread, and an exploded view of a Geo Metro manual trans. I keep a spare manual trans in my Garage (Just For this kind of purpose as a back up). If it makes you feel better Doc, they also sell low mile JDM Manual transmissions on E-Bay or I'm betting Crvett69 knows where to find them? You can do this job after the Phoenix rebuild Doc. My Son and I pulled one out, put a new clutch kit in and reinstalled the whole deal in a day. Besides Doc, if you pull the trans and find out that it's just a Throwout or pilot bearing that's causing the noises..........No rebuild of your current trans is needed, just re-install new gear oil when you done!

Yeah pulling the tranny is not really bad after doing it once. I'd get a ball joint separator. That makes things easier when getting the axles out. I went ahead and replaced the CV axles too. They're only about $120 for a set.

Mine had the same noise, and also it went away when depressing the clutch. It wasn't the throwout bearing.

There's a rebuild kit.

http://www.teamswift.net/viewtopic.php?f=9&t=14856

There's the FSM for rebuilding the trans.

You'll also need a 10 ton press to seperate the gears and bearings from the shafts. It's a good excuse to buy more tools. I intend to do this someday. My syncro's are also gone between 2nd & 3rd.

In the mean time, what I did was go to pick n pull and find a trans in a car that had the 12" wheels. Wheels not on the car? Check the spare. I pulled the drain plugs and looked at them. There's a magnet there. I also stuck my finger in the drain hole and felt around for chunks of metal. Made my best guess and pulled the engine and trans. Special that day, any engine & trans $200. I lucked out. The trans was good. The engine is now waiting to be reassembled.

I recently pulled the trans out of a x fi parts car. The trans had a oil & grim all over it so cleaned it in the parts washer and found globs of grey silicon where someone has had it apart. I don't want to put it in the car and have it leaking. How difficult is it to separate trans to inspect,replace input shaft seal, shifter seal and reseal. What i don't know is whether i can simply unbolt the two hafez and separate or are there other parts that need to be removed first . thank Randall

It's not as simple as that. It has to be dissembled and assembled in a certain order. I recommend you download the images of the transmission part of the factory service manual from teamswift.com.

I had mine apart a couple years ago to replace the input shaft bearing. I wouldn't have got it back together without the manual.

I thought about rebuilding my transmission, but figured the $250.00 for a used one was the way to go. If you can get a used trans for $65.00, then for God's sake, buy all of them! Seriously man! Replace the bad one, keep a spare, and sell the rest for a profit.

Then when you get time, try and tear down that bad trans and see how much fun they are. I been wrenching all my life, but would not attempt a rebuild on this trans unless it was an extra.

If you scroll to GM Line Rat's post and look at the numbered exploded view of the
Transmission....

Which part (numbered) wears out firstest / mostest ?

My Transmission makes a loud "coffee grinder" sound when cold with the clutch pedal
out.
Seems to come from the right side of the Transmission facing the engine compartment.

The sound goes away when I press the pedal in - can't be the throwout bearing!

So...which numbered part (bearing) would wear out first or most to cause such
a noise?

I suppose it makes that same noise as I am driving, but the road noise covers it.

Does whatever bearing wear that causes this noise need to be a lot of wear?
...a lot of play in the bearing?

I am wondering how long I can get away w/o rebuilding the Transmission....

Someone on this Forum said you can drive the transmission even if it makes a
lot of hideous noise before anything actually breaks !

Funny that my throw-out bearing has outlasted the main Transmission bearings themselves!

It is cold out here in Spokane and winter comes...I don't want to fart with my
transmission until it REALLY, REALLY has to be done. I am too old now to
do it just for the grins of it...how long can I put it off?

PS - seems like every time I get a car REALLY fixed up nice, something happens
to it. DEER - Fender Bender - Totaled - something!

My trans started grinding like yours is described and I thought it was a throwout bearing or something, but it ended up being internal. I am not sure what bearings they were according to the pics, but it was the main shaft bearings. I got about 5,000 miles from it when I first noticed the noise was a problem. It got so bad, that I was afraid to keep driving because of fears the trans would lock up causing a crash.

I recently pulled the trans out of a x fi parts car.

That's going to have a taller gear ratio than your standard tranny. Good for mileage, bad for acceleration.

Bill,

The bearing that wore out on mine was number 38 but that's the closest one to the left while facing the engine compartment. The bearing farthest to the right is number 4 which is a tapered roller. If my car were making the noises you describe I would pull the black metal cover and have a look. I don't think you can change the bearing from there but you could grab the end of the shaft and see if it is loose. Could probably also start the car with the cover removed and see if the shaft moves around.

Here is a thread which I found from a while back which has some pics by mechanic matt. I meant to post this link in one of the recent auto transmission threads as I also added a few pics of the auto rebuild.

The pics don't have enough info to do the work of course but should be of interest to anyone thinking of rebuilding their transmission.

Thanks I down loaded the manual but have not got started on the tear down. The trans I have in the car is fine but it has the 4.10 and I would like the mileage of the 3.79 .I have already installed the xfi cam, not much difference in mileage Thanks Randall
