GL-3 gear oil, I think 75W-90 should serve.
Do not use GL-5 (and I've still got to change that on my own site...) no matter what the manual sez. GL-5 contains added sulphur as an "Extreme Pressure Lubricant," and the Aisin transmissions use bronze synchronizer rings. Sulphur is antagonistic to copper and copper alloys, and will rapidly accelerate wear.
I usually use Sta-Lube gear oil - it's what I can find easily, and it works well.
However, whatever brand you use, whatever weight you use, make sure it's GL-3 (preferred) or GL-4 (acceptable.) If all the parts house has on the shelf is GL-5, go somewhere else.

Many have reported (including me) that Redline MTL or MTL90 works very well and alleviates a lot of cold shifting problems.

Redline MT-90 Synthetic. Fixed my cold shifting problems.
www.myoilshop.com has the best price I have found online for most any Redline product.
When you checkout, enter "675421" where it says "enter dealer code" to receive a 10% discount.

I use Syncromesh by Penzoil. Had 188k on my XJ, previous owner never change fluid. Was sticking a little going into second. Once I changed fluid to the Syncromesh it was like a new tranny.

I used the NAPA house brand GL4 after I rebuilt my AX15. I was thinking I would run the cheap stuff for a week until the new synchros and bearings settled in, drain it, and refill with the good stuff. It shifted so bad with the NAPA stuff I thought I buggered the rebuild. I couldn't get it into 1st gear without it grinding when it was cold!mackamitsu said:
I almost pulled the tranny back out, but instead I drained it 3 days later and put in the RedLine. The difference was like night and day. The Redline shifted very smoothly, especially when cold. BTW, the NAPA GL4 has some sulfurs which will shorten the life of the brass synchros.

Odd I've had a little stiff shifting now and then, I just chalked it up to the 298 thou on the clock. I guess I'll be changing it out payday, I'm about due anyways.
