Gear box oil grade please help

[John B]

Hi me again :augie. I'm trying to find the correct oil grade for my gearbox as my last post said but I have been on the comma site as suggested and had a look but I've been told 3 different things by different motor factors and am worried as I know if I use the wrong oil I could feck up my gearbox :nenau. Also I want to do the transfer box and also front diff. Please help :doh. John

Defo GL4 grade oil in the manual gearbox on these trucks, GL5 eats some of the internal bushes.

75/90 GL4 is what I used and what's recommended in the book I think.

Think I got 80-90 gl4 shop said gl5 eats copper in the box but to save starting a new thread how many liters my box took 5 and still wants more

Yeah I got 80/90 gl4 in the end but was hoping a gallon would do the box and the transfer:doh

With what I have seen on the comma site the transfer box takes ATF also recons 3.5 liters for gearbox as well

I had this issue with rick, I had bought all oil for terrano, and if i remember rightly the gearbox took more than on a website, however, it also took less on one of the diffs.

As it happened rick saved my bacon and had some of the oil :thumb2

Maybe rick can remember what grade? :nenau
