So, I just bothered Toyota Motor Sales USA, Inc about this topic. I found a bunch of different part numbers for OEM 75W LF Toyota Transfer Gear Oil over the past few months at different dealer and Toyota parts websites. I was picking up some other parts at a local dealership and asked them for the current part number (I have a 2023 Tacoma TRD Off-Road), but the guy at the counter couldn't find a current part number- all the ones I provided were discontinued. This was about a couple months ago. My research over the past few months led me to the following numbers:
- 08885-81080; Discontinued (Old school can)
- 08885-81081; Discontinued (Plastic bottle)
- 08885-01806; Discontinued- Superseding part number to 08885-81080
- 00279-DGOLF; Superseding part number to 08885-01806
In the early going of my research into this, I looked up the Redline equivalent, which listed the following compatibility:
- Redline 75w MT LV is compatible with OEM 75w Manual Trans LV Gear Oil 08885-03206;
- AND Redline 75w MT LV is compatible OEM 75w Transfer Gear Oil 08885-81080;
- So then OEM 75w Manual Trans LV Gear Oil should be compatible with OEM 75w Transfer Gear Oil…. right?
I didn't love this line of logic, even though technically it looks like the OEM Toyota 75w LV Manual Trans Gear Oil would at least meet the minimum specs of the Transfer Gear Oil. I've not done any UOAs on either of these fluids but I've read anecdotes that the OEM Toyota Transfer Gear Oil has a more robust additive package, so take that with a grain of salt.
Anyway, on Friday, I submitted an inquiry to TMS USA Inc, and they deferred to and contacted the dealer. This morning, the parts manager called me and provided the following info:
- 00279-DGOLF is the part number they use for 75w LF Transfer Gear Oil for the transfer case which best I can tell, is a newer part number.
And because I followed up for the Differential Fluid part numbers:
- 00279-DGOLT is the part number they use for 75w-85 LT Differential Gear Oil (GL-5)
You can find the 00279-DGOLF at TeqSport for about $50 a bottle with the gaskets/washers I think. I bought it and will be using that when I do my transfer case fluid next month (using Amsoil equivalent for front and rear diffs):
Hope that helps!
