Morning, I plan to change the gear in my gearbox and diffs in the near future. Digging around, is Redline MT90 the correct oil to use?

Any good ?

Thanks Dutch. Does anyone know how to tell the difference between AX5/AX15 and NV3550 gearboxes?

You have an AX15 unless you have a 2000/2001 model.

You have an AX15 unless you have a 2000/2001 model.

It's a 2001; does that = NV3550?

[XJ Fan]

Bump.

I checked Hellfrauds at the weekend, and their literature suggests that GL5 fluid, although makes no distinction between pre and post 2000 models, and I couldn't see any GL3, only GL4 and GL5.

As you can see the NV3500 uses a different oil. When I had mine rebuilt I found out there was a part no for oil...... it worked out cheaper to get the oil from Lighthouse than a dealer.

Part no for oil is 04874464 comes in 1 US quart bottles or 946cc
