Hi MolaKule.
Yep, the OEM MTF is low viscosity, API GL-4, found in the first category of the "Updated List of Dedicated MTF Fluids" that you put in this forum. Thanks for the nice work, really helpful.
Quoting you here :
"A. These MTL fluids are closest to a Kinematic Viscosity of 6.X
[email protected] (About the same viscosity as a Dexron VI) 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 M65 5-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]
6. Redline MT-LV SAE Viscosity Grade 70W/75W Vis
[email protected]°C"
Just fooling around with a cheap home made mix to flush the tranny out. Will be putting in the Redline MT-LV afterwards.
I thought I read the TH&T was API GL-4 as well, but I can't find any specs. Anyway, it's the Super Tech Heavy Duty Tractor Hydraulic and Transmission Fluid. Says it uses high viscosity index base oils...meets Allison C-4; John Deere J20A/B/C, J21A, Hygard J14 B/C, Type 303; Case JIC-145, Hy-Tran, MS-1207, 1208, 1209 and 1220; Caterpillar TO-2; Deutz Allis; Ford New Holland ESN-M2C134-D; International Harvester HY-Tran B-6; Kubota; and many more.
Thanks
