Gear oil AMSOIL or RED LINE

I just did mine today. Used VW haldex fluid for the AWD haldex, and Amsoil SevereGear 75W90 in both the front and rear bevel boxes.

I changed mine initially at 30k and refilled with Amsoil severe gear. Changed it again at 90k and wish I didn’t… the fluid still looked brand new.

Redline MT-LV 70W/75W GL-4

exceeds the Toyota required standards…used it in both my GX460 and my 4R, has been flawless.

Really wish I hadn't waited until 37k miles to switch to Red Line MT-LV 70W/75W GL-4 Gear Oil. Made so much of a difference and there was a ton of debris on the magnetic drain plug.

I used amsoil severe gear. Very nice fluid.

I was trying to choose between redline and Amsoil redline had an exact match for my 2015 OEM weight. Amsoil ships from near me in Wichita Kansas so I chose Amsoil the severe gear 75W 90 and did the differential and transfer case. No issues so far

I order some new drain/fill hardware and the ever-trusty RedLine MT90! Get the car in the air and see dirty fluid on the bottom of the case near the drain plug.

The Redline shockproof gear oil line has performed very well for me in differentials, especially in endurance racing applications where a cooler IS NOT used.

Redline Light ShockProof gear oil. Or Heavy Shockproof if you don't mind your gear changes being a bit notchy until the gearbox heats up.

I disagree with any redline product. I've had 3 VW's always used VW gear oil, never a tranny problem. My Scirocco has 160,000 miles and the tranny has never been touched. Whenever I hear of someone haveing major tranny problems needing a rebuild I've always asked if they were using Redline, and the answer is always yes. See, it is much too slippery for VW transmissions. Yeah your gonna clear up your second gear grind and smooth up the shifts but you causing damage to other parts of the tranny like bearings.
