Updated List of Dedicated MTF Fluids

Quote:
...the GM 88861800 has been tested by "someone" to be a legitimate MTL and/or has a few drops of synchro friction rings, friction modifiers added? In reading your comments on it in the past I assumed it was conventional ATF with a slightly improved add pack.



It has been tested by GM and contains a non-metallic friction modifier not seen on low priced analyses.


Quote:
...but the add pack is quite stout. Since there's no "shifting" or "clutch packs" or "friction rings" in most PS racks or pumps, why the need for a bunch of friction modifiers suitable for "clutching material" in RL PS fluid?


The AW component is more than sufficient for MT's specifiying a dedicated GL-4 MTF.

There is a component in there that is multi-functional, that is, it serves more than one purpose or function.
 
Thanks MolaKule for keeping up with this comprehensive and informative list. Regarding the BG Synchroshift II product and according to this spec sheet dated in 2017 the Viscosity, cSt @ 100°C (212°F) = 7.11

I will take this opportunity to report that I have used this product successfully* in my five speed manual transmission 012 FWD (2004 Passat TDI) for the last 100K miles (approx.). FYI this is a longitudinal type transmission that specs the so called GL-4+ (G052 911 A1-A2)

* Of course there is always room for improvement and I will discuss this in a separate dedicated thread

Thank you and I will update my list as it appears there was a formula change since 2012, see pic below.

And if anyone else has a VOA or valid Properties Data Sheet on any MTF's please send a PM or post it here.

Here is an updated list of dedicated GL-4 and a few GL-5 MTL's. Much confusion over the viscosities (thickness) of MTF fluids is the result of the SAE gear oil charts and its ranges seen at: https://bobistheoilguy.com/viscosity-charts/

NOTE: This list is only a “suggested” list of MTFs. It is not an endorsement of any one fluid, nor is it implied that any one fluid will cure problems in MTs that have design problems or those that have excessive wear.

A. These MTL fluids are closest to a Kinematic Viscosity of 6.x cSt@100C (About the same viscosity as a DexronVI) and SAE 70 or so are:

  2. BMW (Pentosin) MTF-LT-3
  3. Honda MTII or MTF 2.
  4. Ford FML-XT-11-QDC
  5. Volvo Manual Transmission Fluid (6.4 cSt)

  9. Pentosin FFL-4
  10. Redline Power Steering Fluid
C. The next higher Next: Castrols Syntrans V FE 75W-80 8.0cSt

D. Then Redline DCTF Dual Clutch Transmission Fluid (8.1 cSt)

E. The next higher viscosity MTL would be BG Synchroshift II (8.2 cSt)

F. The next higher viscosity is Mopar Type MS-9417 MTL 9.0cSt

G. Valvoline MTF Part Number 811095 9.2 cSt

H. The next higher viscosity MTL would be Pennzoil Synchromesh 9.3 cSt

I. The next group of MTL’s are in the 10.x cSt (SAE 75W80) range:

  4. Castrol Syntrans Transaxle 75w-90
  5. Ford XT-75W90-QGT (Carries a GL-5 rating as well)
  6. Ford MOTORCRAFT® Full Synthetic Manual Transmission Fluid XT-M5-QS
  7. Subaru Extra-S Gear & Transmission Fluid carries a GL-5 Rating because it is used in common sump driveline systems.
  8. ACDelco 10-4059 GL-4 75W-90 Manual Transmission Fluid
  9. ACDelco 89021806 For use in MA5 manual transmission for GMT 345, GMT 355 Trucks and GMX 020 Cobalt Pursuit and G5 Passenger only. Caution: Rated at GL-3 (ExxonMobil fluid).

Thx MolaKule...

Can you please advise what was added, changed? I think there was a change to the BG Synchro Shift II?

I find it strange that Blackstone labels it 75W-80... but your list categories, Mola, have it as a (Low) 70W-75, do you not?

BG Synchroshift II was moved from category C. to category B. as the above list illustrates.

I wouldn't concern myself with the SAE gear oil specs since each SAE category covers a wide span of viscosities. As I have stated before, MTF formulations are usually a few centistokes lower in viscosity than their Hypoid gear lube counterparts.

That it does.
 
For the Jeep JK with the Mercedes supplied 6 speed manual, Chrysler has their NSG370 / NV3500 that is supposedly a full synthetic, but it's like $25.00 a quart.

I've used the Pennzoil and Valvoline MTF in the past

Are these (Pennzoil and Valvoline) full synthetics ??

Thanks in advance

The question should be: "What is the actual viscosity of the OEM MTF in terms of the kinematic viscosity in cSt@100C. Take a sample and post the analysis here so we can attempt to match it up.

The Pennzoil and Valvoline 'synchromeshes' are blends of various groups of base oils with specific synchromesh DI additive packages.
 
I updated the list on 7/20/2020 and it was posted on many other threads:


NOTE: This list is only a “summary” list of MTFs available in the MTF Lubricant Market. It is not an endorsement nor a critique of any one fluid, nor is it implied that any one fluid will cure problems in MTs that have design problems or those that have excessive wear.

11. MOTUL GEAR 300 GL-4/GL-5 (PRODUCT NUMBER 100118)
 
@MolaKule, since you seem to recommend the motul gear 300, do you happen to know if the fluid below would be suitable for a manual gearbox, t-case as well as for axles, where it is recommended 75W-90 gl4/5 in gearbox and t-case, and 80W-90 gl5 in axles. By looking at the data sheet, the sharped eye will certainly notice the similarities between the "ingredients" (pao, olefin sulphides and magnesium metaborate).

I don't recommend fluids I suggest a list of choices available in the general marketplace.

Similarities between which products?
 
Similarities between which products?
The first sds I posted was about yacco bvx 1000 75w-90, another gl4/5 dual rated fluid and marketed as suitable for m/t and axles, basically the same "signature" (for lack of a better word) as motul gear 300 75w-90. I wanted to ask if it could be considered as an alternative to motul? Are you familiar with these compounds? Probably from the "zols" eh?
