2019 diff fluid q?

im working on my wife's boyfriends Toyota Tacoma 2019. its at like 64k I want to change it.
what is the general consensus on diff fluid to use?
its a sr5 with the 6 speed limited slip version.

what are my options from mid to best to use and is there a Huge difference between the fluids. is there a war going on about the diff fluids or is it pretty set in stone with that severe slip stuff?

also are these the Tacomas with transmission issues? was it gen 3 with trans issues or early gen 3s? did the fix it in the 2019 models if they did have issues or a gen 3 issue all together.
if that's an issue is there any preventive maintenance I can do?

 

The Tacoma doesn't come with a traditional LSD.
It's an E-LSD diff, or A-LSD, if you will..

 

Wait a minute - your wife has a boyfriend? And you’re working on his truck?

Call me old fashioned, but he can work on his own truck!

 

Is it Friday?

 

Welcome to the forum

The specification is for a GL-5 rated 75W-85 gear oil, most folks use

$29 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90.

Section 9 in your owners manual, starting around page 567, gives all the lubricant specifications plus lots of other data.

Any reputable brand meeting specifications will serve fine, a limited slip additive is not needed as these trucks use an "electronic" LS which uses the anti-lock brake system.

 

At least he's not asking how much brake fluid one can lose before brakes fail. You know, asking for a friend. "Wife's boyfriend" with a straight face is a new one on TW. Good on you for working on his Taco.

Any 75w90 will work. Lots of people use Valvoline, RedLine, Lucas, Amsoil...

 

Huh?

 

Fuck Jody, he can work on his own truck...

Stop being a beta...drain every fluid on the truck, then give it back to him

 

Yeah like everyone on here works on their own truck LOL!
