Fluids change

Hi, I just bought a 2013 Tacoma reg cab. Manual trans. 2.7l 4x4 with 143000 miles.
I want.to change out all the fluids, owners manual call for 75w 85 and 75w90 for differentials transfer case and manual trans fluid. Can I just use

$30 Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

Mobil 1 75w 90 for all applications, and make it easy?
From what I'm reading the limited slip additives shouldn't matter....Thanks

 

Yes, you can use

$30 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 Mobil 1 and you’re correct, you don’t have to worry about the limited slip rear.

 

Yes you can. Thats what I did and didn't have any problems.

 

When was the last time the coolant was changed ?

 

Good question...lol. put that on my list!

 

Coolant, serpentine belt, brake fluid, bleed the clutch as well if no known servicing of those too.

 

You might find that any synthetic gear oil you use changes the shift quality of the manual trans. My layman's understanding is that most synthetic gear oils are optimized for gear to gear protection and that makes it too slippery for the syncros in the tranny to properly grab. Regardless of my bad description, lots of testimony here on Tacoma World echos my experience that Mobil 1 and other common synthetic gear oils in the tranny degrade shift quality. Seems Redline MT90 is the go-to (and works buttery smooth in my experience) but if Redline's price tag scares you away, a cheap, non-synthetic

$30 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 will actually shift better than common synthetics.

That said, I use Mobil 1 for everything else.
