94 Wrangler AX 15 transmission oil change, which oil to use?
I have a 94 wrangler 4l limited with an AX 15 transmission, now, I have to change the oil as it is beginning to refuse to change gear sometimes. My question is what type of oil can i use, the owners manual says GL5 75w-90
very expensive in the U.k. On looking on the forums many people say not to use GL5 oil, and some say the manufacturer now recomends 10w-30 synthetic engine oil, a lot cheaper. I need some clarification please help.

This isn't totally true. Back when the old GL5 rating and synchro eating fluid was on the market Chrysler recommended a change to 10W30 motor oil. Any of the "modern" 75W90 gear oils, full syn is better, or 10W30 motor oil, full syn is better, can be used.
