AWD starlet gearbox

[tip]

hello i have an AWD starlet with a GLANZA engine in it, i'd like to know which oil i can use for the gearbox.

Have a look at the Gearbox code - Trans/Axle - behind the VIN number under the bonnet first!

Then have a look here

Recommended API GL-4
SAE 75W-90

Models before 1996
C140,C141,C150,C153 - 2.4L
C52 - 2.6L

Models after 1996
C140, C150, C153 - 1.9L
C56 (WITH LSD) - 2.2L
C56 (Without LSD) - 1.9L
C50F - 2.2L

i have a sticker on my AWD box that says 75w-90 gl-5

thats what i used and it was fine. just make sure it is suitable for a syncromesh gearbox.

there was a thread posted previously and gl-4 75w-90 can work better on an older box with a bit of wear on the synchros

What's the model number for AWD Gearbox?

 

[dac69er]

no idea. i can have a look when i get a chance. where is the model number usually stamped?

The 4WD box is c50f, didn't know they did an AWD.

4wd, awd, same difference

 

[GTwayne]

It's not the same, but i assume the op meant 4WD.

It just says 75-90 on my drain and fill plugs, no GLI rating.

Have a look at my previous post. Under the binnet look for Trans\Axle next to Vin number

 

[dac69er]

if you want to split hairs the box itself is actually awd as it will drive the front and rear wheels all the time, but due to the centre diff it is actually a 4wd vehicle.

i found after drag racing on new oil for a year that the gearbox oil was fine but transfer box seems to be under much more heat/pressure- oil had turned to gunk. would change that more regular i think

I agree, JDM Honda senior mechanic and a man who does a lot of awesome tuning with over 1K BHP, recommend to change the gearbox oil every time you change your Engine oil, explaining it as they get a lot of pressure and get very hot and where is engine has coolant the gearbox has nothing but oil -)

I have seen many times that some drag racers use either all automatic transmission fluid or a mix of box oil and auto fluid, the idea being that auto trans fluid has less density and creates less losses in the box.

Anyone any thoughts on this or know of it being done?
