Manual transmission fluid

It may be really tight. If so, try a little heat. Fill it till it runs out that hole.

Thats the good stuff :) Posted Image
I have been using 5W30 regular oil in my Geo, should I be changing it over to a 0W30 Synthetic oil on my next oil change? If so do I need to do a flush before putting in the new oil? I did a seafoam 200 miles prior to my last oil change.

I am also searching on how to change the Tranny fluid, so far have only found what I need to use not the how too's.

Okay, found out how to drain and fill the transmission. Do I need to flush it with something when I change the fluid and how?
Now I am super confused, I dug out the owners manual for my 93 Geo Metro 3/1.0 5spd. In the book it says "manual transaxle to use (GL-5 Gear Oil) 2.5 gt. (2.4L)
Somewhere else in here (can't find it now) someone had mentioned they were to use as per GM Synchromesh GL-5 on their 93. (is GL-5 Gear Oil and Synchromesh GL-5 the same thing?)
I know that as time passes products are improved on and changes made, which is the way to go

No flush needed for the engine or the transmission.

5W-30 is recommended, 0W-30 is a newer product that acts exactly the same except it is a bit thinner when cold. Gets around inside the engine faster when first started and should give 1/100 mpg improvement in gas mileage. Synthetic is better than regular, but is also much more expensive, your choice. Nothing wrong with the regular oil, synthetic's main advantage is that it lasts longer.

You can find three different gear lube recommendations in the Metro manuals, no one knows why they can't get their act together there. Experience of thousands of Suzuki/Metro owners is that Pennsoil Synchromesh works best. It also is thinner for better mileage and doesn't stink like gear lube does.

Yeah gear oil smells bad. Everyone really likes the SM. I run 30w motor oil in my trans. The SM has friction modifiers for a lined sync in some of the truck units. I think its over priced for what you get. There has been huge debates over this same topic here. Many times. Woodie is right. No flush needed. But it is a good idea to change the fluid out when its hot. Just after you turn the engine off. It has all the particals floating in it. When you drain it hot. They don't have a chance to settle. And changing it out about every 12k or so is a good thing.

That picture is pure porn!
That's my "new metro" package :) a great gift for a friend or family member who has just acquired a metro :) :rocker
Very sorry! Just have to throw my 2 cents into this "Syncromesh" thing. It doesn't appear that the Pennzoil product is full synthetic. Having been an Amsoil dealer for 8 years - and having been to "Amsoil University" - I have to recommend Amsoil's Transmission Syncromesh 80W90 Synthetic GL-4 product. The original gear oil from the factory is full synthetic. My long-term experience with Amsoil's products is that their chemical engineers are absolutely the best on the planet. They build the strongest, slickest, longest-lasting lubes in the world. At $15.75 per quart, you'll find that once installed, it "drives like it's supposed to drive." amsoil.com

How nice! A discussion about transaxle fluids. This never gets discussed on this forum as much as it should... ;)

Couple of questions if you don't mind. And keep in mind I am not speaking out against the quality of Amsoil products. I have always considered them to be of excpetional quality. And at twice the price, they should be. :lol

Anyway, when you were at Amsoil University, did they happen to teach you what company it was that GM paid to make their GM 12345349 transaxle fluid to put in their transaxles and GM labeled bottles to sell? I can give you a hint - it wasn't Amsoil. Did they teach you that there must have been some tragic screwup at GM, whereby they inadvertently contracted the wrong company to make the wrong fluid to put in their transaxles and GM labeled bottles? :hmm

Finally, would you please explain to us the logic of the statement "drives like it is supposed to drive" which seems to imply that using the product it was designed to have and they purchased to install in their transaxles from the factory didn't/doesn't make it drive like it is supposed to becasue it wasn't Amsoil? This is most confusing.

Also, what specific problems have those of us who have been using the factory spec transaxle fluid for years and years having that we are apparently not aware of? :hmm

And don't get me started on your implied claim that you are actually qualified to objectively evaluate the quality of the engineering of Amsoil lubrication products against that of other comparable companies worldwide. Wait,you did... :smackface :whistle

Again, the quality of Amsoil products in my opinion is excellent. However, my personal suggestion is that you don't spoil the credibility of both Amsoil and yourself by spewing flowery marketing pr that suggests that using the original factory choice for spec transaxle fluid that has worked incredibly well and reliably for many people for many years is a mistake. If you want to say Amsoil is great stuff, spend twice the money to try it, fine.

I think its a bot or a ad spammer. Only 2 pists and one is bragging about snake oil products. Amsoil us good oil, no doubt, but they do the hard sale abd infomercial type hype. I prefer Mobil 1 or Castrol Syntec for synthetics for lower pricing and much better availibity. If Amsoil is so much better, why not make it easier to buy? It reminds me if those pyramid schemes.

He's real, but in my opinion just needs to get a bit more realistic about the fluids. :dunno

If you are trying to convince those of use already using the original spec fluid and love the performance, to get us to spend twice as much darn well better make the car fly, and go to the store for a beer run while we sit on the couch. And get 75 mpg doing it. :D

Maybe he is. His post reads like a commercial.

But I am using two Amzoil products and am very happy with them.

One is the said Amzoil synchromesh fluid. A noticeable difference is how it works at low temperatures. With standard 75W90 Mobil Synthetic, it may be difficult to shift into gear before the transmission warms up. I hate it when I have to push the stick hard, vividly imagining the plight of shifting fork and synchro ring. No such problems with Amzoil synchromesh fluid. This fluid cures worn synchro rings. In my Nissan truck, it cured the crunchy 5th gear. 75W90 accumulates fine metal dust - it is so thick that fine particles never settle. After the specified 30K interval, the oil may look like grey silver paint. Amzoil fluid is much thinner, and it remains clear for longer time.

I remember that someone at the Ecomodder forum tested the claim that Amzoil synchromesh reduces friction losses. He drove Metro transmission with electric motor to certain speed, and measured electric power consumption. Amzoil fluid reduced power consumption about 20% compared to 75W90.

Another Amzoil product that I like is their 1:100 2 cycle oil. I do a lot of firewood cutting, and have been using this oil in all my chain saws. It works fine at 1:100, no bullshit. It can be added to gasoline at 1:200 - 1:400 for breaking in a rebuilt car engine. No other manufacturer has 2 cycle oil that works at such high dilution.

He's not. Ask him. ;) Read his initial thread, that one's not a commercial for his Amsoil business.

And no such problems with the aforementioned GM 12345349/Synchromesh by Pennzoil either.

Does the Mobil 1 meet the specified GM pn/spec? Did GM change the spec in later (Chevy) year models?

Cures them? It makes them unworn?

"And no such problems with the aforementioned GM 12345349/Synchromesh by Pennzoil either."

Yes, I believe Pennzoil Synchromesh is pretty much equivalent to the Amzoil fluid.

"Does the Mobil 1 meet the specified GM pn/spec?"

On the bottle it says it meets or exceeds OEM specifications.

"Did GM change the spec in later (Chevy) year models?"

They did not. And after 2000 they did not care. If Chevy still produced Metros at this time, they would likely upgrade their recommendations to better modern fluids.

[/quote]It doesn't, of course. It makes ring-cone engagement less dependent on the condition of ring threads.

Oh, is that right? Says who? The factory gear oil is indistinguishable from Synchromesh.

And Synchromesh does exactly the same at exactly half the price.
