1984 4x4 4runner Manual Tranny

oil - diffs (6 quarts total) API GL-5 Hypoid Gear Oil SAE 80W-90
Manual Tranny 5 quarts total API GL4 or GL5 SAE 70W-90
transfer - 3 quarts total API GL4 or GL5 SAE 75W-90
Dual Transfer Case - 1 quart API GL4 or GL5 SAE 75W-90

Brakes - Dot 3
Power Steering - Dextron or Dexron II

The amounts are a little more than needed so I can have some extras.

 

sounds about right.

 

thanks

 

x2 but I would add that 70W-90, 75W-90 and 80W-90 are for all practicle purposes the same thing. I wouldn't necessarily buy different oils.

I was sold on Redline Synthetic (for whatever reason) when I rebuilt my axles and changed all the fluids. I used their 75W-90 (without the non-slip additive) in the diffs and transfer case and their MT-90 in the transmission as several people had reported smoother shifting with that particular product.

I think you could use 75W-90 everywhere and be just fine if you only wanted to buy one product.

Also, just fyi, all Dextron transmission fluids are backwards compatible so anyone of them should work for the power steering.

 

Is this the stuff you are talking about? I didn't see anything about the non-slip additive you are talking about.

I'm guessing his is the tranny fluid you are talking about:

Will this work for the Power steering:

I didn't see brake fluid from Redline, but I think i could just get that at NAPA.

 

Answers above. Any quality brake fluid should be fine.

 

Been doing a lot of reading about Red-line as well as other gear oils myself since I'm due for all my major fluid changes in the drivetrain. I keep reading about GL5 lubricants eating away at yellow metals such as the brass synchronizers in your transmission and those that have used Gl5 lubricants are getting hard shifting and other issues. I was told to check out Red-line MT90 because its specifically designed for manual transmissions that specify GL4 gear oil. I was also told that you can use GL5 in the T-case and both diffs.

 

good stuff. I ordered up the stuff from the red line site. Cost me $220 for enough fluids to change both diffs, tranny, transfer, power steering. That was with 3day shipping. I guess it's the price ya pay to put some good stuff in it.

Luckily I've stopped almost all the leaks. I have one at the rear output shaft/transfer case and one possible on the tranny seal on the engine side (either that or the rear main seal, not sure which one yet, but doesn't really matter cause I'd replace em both if I have to do one).

 

Let me know how it works for you. I'm fixing to take a $500.00 plunge on various parts including Red-line oils, maybe you could give us a good review on how well it works!!!

 

Yeah, not a problem. I'm just pissed that I've got a couple leaks and my expensive oil will be just leaking away. ha ha. Guess it's incentive to fix them.
