Title: Proton/MMC Gearbox ratio


g88 - January 15, 2007 04:04 AM (GMT)
Just sharing with everyone since i found this information is interesting.

Anyway, am not sure have anyone of you ever hear from others where different year/batch of Saga/Iswara/Wira's gearbox is have different gear ratio (Assuming am comparing all carby 1.5 F5M21 gearbox)

The answer is : YES ! Different batch of SAME MODEL gearbox possible to have different ratio according to the gearbox last 4 alphabet

Example like this :-

Gearbox claimed to be taken out from Saga 1.5 1990-1992

Gearbox from Iswara Aeroback 4G13 year 2003-2005

Upon finding, i found that both two F5M21 gearbox FIRST GEAR and FIFTH GEAR is different with each others.

I will try to upload more concrete info later as i am compiling these information now.

Btw, if any of you have answer question about Proton/MMC gearbox information/ratio do not hesitate to post here and i will try my best to give the answer :) REMEMBER pls give me the FULL gearbox code if you wanna do COMPARISON :)

Not to forget tell me the year of the car/gearbox wor aside the code.

Adios ....


jeremylj - January 15, 2007 06:12 AM (GMT)
i dont have the code but i have something to share

Wira 1.5 year 93(carbie)/Manual 5 speed=5th gear at speed 110km/h @3500RPM

Wira 1.5 year 02(EFI)/Manual 5 speed = 5th gear at speed 110km/h @3000RPM

not to forget, both are running on stock 13 inch with 175/70/13 tyres..

drexchan - January 15, 2007 06:44 AM (GMT)
but my car, year 2004, 3000rpm in 5th ~100km/h.

drexchan - January 15, 2007 06:58 AM (GMT)
BTW, where is the model number located. Need to check mine.

g88 - January 15, 2007 07:05 AM (GMT)
Here's the information

Dun ask me why Proton uses older batch gearbox on Iswara car...

EXP stand for EXPORT since JDM will NEVER USE THESE CODE gearbox even ratio might be same.

Look below your distributor. On the gearbox.

drexchan - January 15, 2007 07:42 AM (GMT)
I have the data for F4M2, F5M2, F5M3 and W5M3 from 1992 to 1996.

VRBE and VRAC not included.

i also have this one but i have also a different version where start from 1987 till 1996 model ^_^

Before 1990 all not using F5M coding.

So what's your gearbox code model ?

drexchan - January 15, 2007 08:08 AM (GMT)
car is not with me lar..

g88 - January 15, 2007 10:45 AM (GMT)
Just check another unit of 1996 Iswara 1.3 Sedan manual and 2002 Iswara Aeroback 1.3

Both car Gearbox code is F5M211-VRAC.

As for information now, Saga and Iswara is NOT using SAME GEAR RATIO gearbox

drexchan - January 15, 2007 11:12 AM (GMT)
we might as well check all Proton models with 4G13 and 4G15 engine and compile a list of gearbox model and it's gear ratio.

Saga, Iswara, Wira, Satria, Arena.

g88 - January 15, 2007 11:26 AM (GMT)
I just worry Proton suka hati this year/batch Saga put this gear ratio gearbox and that different...then it would be very hard to get the list ler...

Why not start with WAC member's car first :D

drexchan - January 15, 2007 05:08 PM (GMT)
Mine, year 2004 4G15 SVDO, F5M211-VRJE.

I was previously calculating the RPM-speed relationship using a "D ratio" as in your table. The speed reading wasn't in-sync with the RPM.

Now, I have just recalculated back my gear ratio and RPM-speed relationship. Calculated speed at 3000 rpm in 5th gear is 99.7km/h, speedo reading is 100km/h!

It means, 0-100 time now is indeed 11.6 sec base on speedo reading..

g88 - January 16, 2007 12:16 AM (GMT)
OK, let compile the list

1. Year 1996 Iswara 1.3 Sedan Carby - F5M211-VRAC
2. Year 2002 Iswara 1.3 Aeroback Carby - F5M211-VRAC
3. Year 2004 Wira 1.5 Sedan EFi SVDO - F5M211-VRJE

Thanks for the input. Can share how to calculate Speedo vs RPM based on gear ratio ar ??

This is whaT 1 Use.

Input the tyre size, gear ratios. The speed at the rpm interval will be calculated. I made this excel spreadsheet myself.

khguan - January 17, 2007 07:11 AM (GMT)
till now.. seems like wira and iswara using diff gear ratios... i wonder the older batches of wira n iswara using the same gear ratios as the present models or not...

g88 - January 17, 2007 07:55 AM (GMT)
I am keen to know Iswara 1.5 and Wira 1.3 also...

drexchan - January 17, 2007 08:12 AM (GMT)
In the User Manual for my car, itstated that all 1.3 and 1.5 Wira shares the same gear ratio (F5M211VRAC). However, it's been proven that the User manual is wrong. My car has a F5M211VRJE instead.

Interestingly, from the same manual the gear ratio for Wira 1.6 is the same as the ratio of a VRJE. The final drive is not stated though.

So, it will be interesting to find out the transmission code for a Wira 1.3 too.

khguan - January 17, 2007 08:38 AM (GMT)
need to ask Gary to check his 1.6..

6. Wira 1.3 Sedan Carby - F5M211-VRBE

drexchan - January 17, 2007 09:15 AM (GMT)
Wira 1.3 carb uses VRBE? That means the gear ratio including the final drive is same as teh Wira 1.5 EFi (VRJE)

khguan - January 17, 2007 10:57 AM (GMT)
wat year is the wira 1.3 carby??

g88 - January 17, 2007 11:14 AM (GMT)

I transplanted a manual gearbox into my Wira. It's originally from a Wira 1.3, using cable clutch. It's a F5M211-VRBE unit. My speedo's under-reading a bit because the original wheel size is 175/70 R13, I'm now using 205/45 R16.

Wira 1.6 uses F5M22 series of gearbox, and I think so does Wira 1.8.

khguan - March 1, 2007 04:59 PM (GMT)
wat engine are u using bro?? y not use 1.5 GB??

pls intro urself in the newbie section ok??

jswong - March 2, 2007 10:49 PM (GMT)
I'm not using 1.5 gearbox because I got this 1.3 gearbox dirt cheap - RM200 only. The rest of the stuff to complete the auto-to-manual conversion were obtained bit by bit, and restored if possible as I went along (i.e. grind down to bare metal with a steel wire brush attachment to a power drill, and then re-coated with enamel).

By the time I had everything in place, I took all the stuff to my mech's place and spent half a day swapping out the gearbox with him.. So, since I was also doing the work with him, he only charged me 50 bucks for labour.

izso - March 3, 2007 11:04 AM (GMT)
You did the work WITH him? You must have a pretty big garage! And how'd you do the grinding and stuff? On the GB itself and all or on your car itself? What's the point of grinding and recoating? Pardon the idiot who doesn't know things like these (ie-me)

jswong - March 4, 2007 05:08 PM (GMT)
Uhmmm.. I grinded the parts and recoated them with enamel to protect the parts laa.. because the half cut parts are covered in rust.. just re-painting won't do, have to grind down to bare metal and use an adhesive-base enamel to recoat it.

By the time I took all the parts to my mech, he thought that they were all brand-new! :D That's the other advantage of reconditioning the parts.. they don't look like old junkyard parts and hopefully, they'll last longer than just simply transplanting rusty parts into the car, no?

I did the job at the mech's workshop.. I drove there with the parts in the morning, and proceeded to dismantle and replace stuff. Half-day job only, quite fast when we're not fumbling or encountering any problems.. only that I had to re-drill the firewall and re-fabricate the clutch cable harness with water plumbing parts because the mechanic did a sh1t job for that.

khguan - March 4, 2007 05:36 PM (GMT)
good job with the restoration eh!!

izso - March 4, 2007 08:02 PM (GMT)
jswong - if you did all that, what for you need the mech?

khguan - March 5, 2007 02:10 AM (GMT)
the mech do the dismantling n installation lo.. :lol:

jswong - March 5, 2007 02:31 AM (GMT)
Uhmmm.. mech had all the tools what.. and the car lift, and all those jacks, pneumatic tools, etc.

Besides, I've never dismantled a gearbox before, so it was a good learning experience to see what goes where.

drexchan - March 5, 2007 02:32 AM (GMT)
which brand of enamel paint that you were using?
