End all Protege Transmission Thread.

How long do the stock clutches last? It feels weak to begin with, and I am an aggressive driver.
Depends on a milliion variables. But mostly, how you drive it and how much power you have.

Shameless Plug - I have a stock clutch for sale with 440 miles on it if you're interested.
 
i've had mine for 83K with no slippage. It is starting to get a little sticky lately, I believe. Could just need a fluid replacement. I am not an easy going driver, either.
 
What I got back from corksport regarding their 1.6/1.8 differential:

Hello

This LSD if for the F series transmission used in the 99-02 models with the 1.6 and the 1.8. It will work in earlier F series transmissions as well.

Thanks
Derrick
 
I realized we hadn't put up most of the part numbers in this thread for the main tranny parts... so here are a few:


Synchros: GC011726Y
Speedo Gear: G501-17-341A
LockNuts: F520-17-628 and F521-17-628A
Oil Seals: F003-27-238B
Bearings: G5R0-27-350B
LSD: GS01-27-190A
Forks: G501-17-40YA and GC01-17-40XA

Keywords: Tranny part numbers synchro bearing number transmission upgrade MSP LSD

Probably can't have these in too many places as that just makes them all the easier to find when needed.
 
There are pics of the internals of the tranny on here somewhere for my tranny install... so you'd just need to locate that!

Later,

Steve
 
Sorry, thought I'd jump in here before Edwin does. All 2.0L Protege's came with the G15M-R tranny. No one has a G5M-R.
 
2 year old thread, TheMan would have jumped in by now, I imagine.
 
funny you revived this. Wasn't long after I posted the 83k comment that the transmission let go. Had a rebuild by AAMCO... Been working ever since, but the gears are more sticky than they used to be. Still, I drive it hard with a turbo at 7psi (stock internals) and when they replaced the tranny I threw in a Stage 2 clutch.
 
ok guys I found some interesting information about these transmission and shreddin 3rd gear

http://users.tpg.com.au/tgrandja/images/Articles/4wd_gearbox_solution.htm

The info is based on someone who did rally driving with 323gtx awd, which have a similary gearbox than ours.

It seems the main problem is the bearing, the bearing sleeve can slip and rotate in the bearing groove, which wears out the case (caused by sideload). more wear = more play within the primary and secondary shaft. Please read the link to understand my explaination.

I've read the thread and there is a lot of really good info there.
Its explains the problem i've been having to a Tee. So now I'd like to know where I can get this fix, and solve my problem. 270ftlb of torque should not be destroying this many 3 rd gears (3 in 3 months).
 
Doesn't PAR have a solution for the bearing sleeve caps? I could have sworn they did...
