Looking at a '90 TSB on lubrication.
It says to add this mitsu modifier that comes with the syncho kit to 75/85 w gl-4.

Is this modifier the same as LSD additve by StaLube?

don't know but be carefull about adding the friction modifier to the LSD. Add only enough to stop the chatter, not the hwhole bottle.

Bob, I think Dave's referring to using an additive in the tranny itself, not the rear end. Not uncommon (GM Synchromesh comes to mind), but not used in most of today's manuals.


Fasteddy's advice is occasionally sound...

I went seaching for GM synchro yesterday ,,no one carries it in these parts and a service tech at a huge GM dealer here says he hasn't used it in 10 years. I ran it for about 7 well overdo years. Straight I think. It looked pretty watery when I drained it last night,,,I don't recall what the wieght is on the G.B. Syn.

As of 4:am I now have 75/90 gl-5 Valvoline with 4 oz of CRC LSD friction modifier(stuff smells like syncro) in the V5MT-1 ; 75/90 gl-5 in the T-case; 80/90 gl-5 Staylube w 4 oz. Lsd additive in the rear diff.. 20/50 high milage Castrol and 2 quart oil slick running down the mud driveway. I get goofy at 4 am and tend to trip over things.

Speaking of TSBs, there's one on GL4 versus GL5.

MMSA TSB-93-22-001 - MT Transaxle Gear Oil
The manual transmissions/transaxles in Mitsubishi Motors vehiclesMotor require the use of an API GL4 classification gear oil. Using an incorrect API classification gear oil may affect the shift effort and may cause transmission/transaxle component damage.

Use only gear ols having the API classification GL4.

Mitsubishi Diamond Gear Lube - A991ZC2X01 - SAE 75W - 85W GL4, meets this requirement.

CAUTION: Do not use gear oils having an API GL5 classification. GL5 oils have additives shich may chemically react with sintered copper synchronizer rings leading to manual transmission/transaxle damage.


Just found this myself the other day. Also don't like the way my trannies feel at times. Pretty sure I have a GL4-GL5 flavor. Guess I'd better drain them...

I've been using 80W-90, 85W-90, and 85W-140 API GL-5/-4/-3. This was basically what I found at the part store each time when I got ready to change it out. I usually buy out what they have and sometimes need to go to a second store to get enough if all they carry is one or two gallons.

Maybe I should change as well.

I thought I read that somewhere,,,I looked everwhere for gl-4 in 75 / 90. Even went to a petrol distibutor. Everbody says I worry too much or I'm nuts, well they're right on both counts so I couldn't argue.

I called the 800 # on the Valvoline bottles and the tech guy insisted it would not harm my synchros, so I proceeded.

Dave, CRC StaLube still makes the GL4. Part numbers are SL24229 for a quart, and SL24239 for a gallon. You're not crazy, if the FSM specs GL4 instead of GL5, that's what I'd use. Good luck finding it!

NAPA has GL 4 in Stalube but it is like 85/90.

So is Synchro mesh just used as an additive or straight??????
