I'd stay away from anything that says it's GL4/5 compatible. I put that stuff in my transmission and had to replace the transmission less than 6 months after that. If it says GL-4, find something that only says GL-4. Redline and AmsOil are both good. I run Redline in mine now. Nice smooth shifts with no problems.
I got mine from Amazon.com for just under $16/quart.

no, read the FSM for specifics for each item if you want to stay factory. I run the heavy shock proof for the diffs because it keeps the lockers from being loud and obnoxious. I run the MT90 in the transmission and the standard recommended weights from the FSM in the t-case.
I dislike royal purple for two reasons. The rep that came around the shop I worked at, was the most annoying SOB I ever met and their oil is purple and looks dirty right out of the bottle due to the purple dye… makes it harder to tell when it's ready for a change...

I'm about to install my new Marlin HD W56 transmission in my '86 4Runner and I see on their website that they "Strongly recommend" a GL-5 for the first 5-10,000 miles. http://www.marlincrawler.com/tech/gu...allation-notes
i'd guess that all of the gl-5's on the market today will not hurt the yellow metals in our transmissions, assuming that we even have any... wrt the cheap warren unilube coastal stuff that i'm running for break-in:

the redline lube will be a definite improvement over that coastal gear oil... here is a lab report on the motorcraft fluid that i'm going to run, in terms of wear, it doesn't get much better than this:
"My OSA...
2 Full track days and probably about 30 autocrosses over the course of a year. I spent a lot of time on the rev limiter, so that combined with the track miles is why I changed it out 'early'. Looks ok?"
