90w correct fluid type. I use mobil one in
my 83, with 90 w56 transmission, night and
day difference when heated up ( freeway with
5.29's ). I have no experience with redline
products. Hope this helps.... <IMG SRC="smilies/smile.gif" border="0">

I have used 80w90 in my 83 pickup and 85 4Runner for years with no problems. This is recommended by Toyota in the owner's manual.

Figure on about 2 quarts in the tranny and 2 quarts in the transfer case.

MTL and MT-90 are best for the tranny, MTL is a bit thin (70W80), MT-90 is a 75W90 oil, but both are good with synchromesh trannys.

I run Redline shockproof in the transfer and diffs, but 75W90 gear oil is good, too.

Redline gear oils

You can buy an excellent synthetic gear lube at Walmart. Penzoil brand sold for marine lower gear drives (don't mistake the 2 stroke oil!)- it's a 75 or 80/90 - don't recall. About $6.50/quart.

75w/90 GL4 is what is specified for the tranny and Tcase. Avoid GL5, as it is to slippery for the synchros.
I use Redline MT 90, have used it for years. Works much better than conventional gear lube, especially in extreme temps. You will like the way it shifts.
Make sure you get the MT 90, the MTL is a replacement for 10/30 motor oil or ATF. The gear lube for the differentials (GL5) will make the synchros slip and grind. <IMG SRC="smilies/eek.gif" border="0">

i've been thinking about changing my tranny/xfer cse oil for a while now. When it starts cooling down outside, I notice that the gears don't mesh as nicely in 2nd and 3rd, and it kind of bothers me, especially since the oil in there now was put in by Jiffy Lube before I bought the truck, and I don't know what it is (probably some cheap crap). Anyway.....so 75w90 is probably what I'll go with. The coldest it ever gets here is about 50, and that's on a COLD night, never that cold in the day, and in the summer it's about 130 max <IMG SRC="smilies/eek.gif" border="0">

Mories stabilizer mixed with 85/90 gear oil at 50/50 ratio. Try it, you will like it!

I run the same ratio in tranny, t'case, and both diffs. It will also work in power steering pumps.

My neighbor Bob Riggle, the owner/driver of
The '67 Barracuda Hurst Hemi Under Glass,
uses Mories at 100% in the rear end of his car. It's an 1100bhp, blown, injected achohol wheel stander. He was burning up two rearend housings a season till he switched. The load placed on the rearend w/ turning brakes steering the car is enormous!! He also used it in his tow vehicle.
