Fluid type for TC and gearbox for 05 GC

[Brit30-06]

Hi.
Stewatpark is correct in saying the transmission has many names. However, the correct designation as given by Jeep is W5J400.

ATF+4 should be easily available and not too expensive.

Have you an agricultural supplier near to you? Ask for Mobil424 equivalent. Hopefully they will have something in 1 litre containers.

Any fully synthetic 75/140 will be ok for diffs. If you have qd2 you will need the limited slip additive.

yes, ATF+4 i can found not expensive, but i wanted to see if i could use a single fluid for gearbox and TC, like motul ATV VI (at least according to motul fluid finder, but it wrongly lists the NV140 one for this vehicle so the fluid finder might not be correct)

funny thing is that 2L of mopar NV245 fluid costs more than 20L of mobil424

About the diffs, yes, i have QD2, i've found MOTUL GEAR COMPETITION 75W-140 and Valvoline Syn Power Gear Oil 75w/140 / Valvoline Full Synthetic Gear Oil 75W-140 as they already includes the additives

Hi William.
It is not unusual for oil company fluid finders to make this mistake.

Mopar fluids are stupidly expensive. Can you find Petronas products? They offer a transfer case fluid in 1 litre bottles.

This is what i use and it carries the MS10216 Mopar specification.

Just checked and i can't find the powergear4 available, since i hadn't paid attention to petronas before i took a gander at what is compatible with the jeep and what's available.... absolutely nothing, not one of the petronas GC fluids are available here....
