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.
A.These MTL fluids are closest to a Kinematic Viscosity of 6.X cSt@100C (About the same viscosity as Dexron VI ATF) and SAE 70 or so:
1. Castrol Syntrans FE 75W,
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) [Recommended for: type M655-speed with 6-cyl. engine, M66, MTX75 and MMT6 and of the type M56, M58 and M59 from and including model year 1996. Meets Ford specification WSSM2C200-D2]
7. Redline MT-LV SAE Viscosity Grade 70W/75W Vis 6.5cst@100°C
B. The next higher viscosity MTF would be the 7.0 to 7.6 cSt@100C versions(SAE 70W75) (About the same viscosity as the original DexronIII/Merc)
1.Royal Purple's Synchromax
2. Ravenol MTF-2
3. Honda MTF
4. VW part number G052512A2
5. GM Manual Transmission and Transfer Case Fluid
6. BMW (Pentosin MTF 2) MTF-LT-1, 2 ,3
7. Tutelo (Petronus, Italy, Product Code 1402)
8. Penrite Pro Gear 70W75 (Australia)
9. FUCHS Titan Sintofluid FE 75W Manual Transmission Oil. GL-4 75W Gear Oil
10. Redline Power Steering Fluid R
11. RAVENOL STF
Note: C, D and E are often considered popularly as “synchromesh” fluids.
C. The next higher viscosity MTL group is in the 8.0 cSt to 8.9 cSt Range would be:
1. Castrol Syntrans V FE (8.0cSt)
2. Redline DCTF Dual Clutch Transmission Fluid (8.1 cSt)
3, BG Synchroshift II (8.2 cSt)
4. Valvoline MTF Part Number 811095 8.8 cSt
5. RAVENOL PSA (8.9 cSt)
6. Millers Oils TRX SYNTH 75W80 8.7 cSt (Carries a GL-5 rating as well).
D. The next higher viscosity MTL group in the 9.0 to 9.5 cSt range is (SAE75W80):
1. Mopar Type MS-9417 MTL 9.0 cSt
2. Pennzoil Synchromesh 9.0 cSt
3. RAVENOL SSG 9.5 cSt
E. The next group of MTL’s are in the 9.6 to 10.X cSt range (SAE75W80):
1. Redline MTL 75W80
2. Amsoil MTF (9.7 cSt)
3. GM Synchromesh Series
4. Volvo MTF 645
5. Fuchs TITAN SINTOFLUID SAE 75W-80 synthetic MTF (Carries a GL-5 rating as well)
6. Lodexol (Morris Lubricants) MTF
7. Motul MotylGear 75W-80 GL-4/GL-5
F. The next higher viscosity MTL would be a 12.0cSt@100C and SAE 75W85:
1.Redline MT-85
G. The next higher viscosity MTLs in the 14-17 cSt (SAE 75W90) range would be:
1. Amsoil MTG
2. Redline MT-90
3. Castrol Syntrans Multivehicle 75W-90
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 FluidXT-M5-QS
7. ACDelco 10-4059 GL-4 75W-90 Manual Transmission Fluid
8. RAVENOL TSG SAE 75W-9
9. LIQUIMOLY 75W-90 GL4
10. PENNZOIL 75W90 GL-4
11. Motul MotylGEAR 300 GL-4/GL-5
Let me state this again: Before changing an MTF in a vehicle, obtain an OEM fluid sample and post the analysis in
bobistheoilguy.com
so we can attempt to suggest a fluid of similar viscosity and additive signature. This removes a lot of guesswork on your part.
