I just received my redline fluids and crush washers from one of the forum sponsors. I ordered a total of 4 crush washers which came unlabled in a bag. There are two of each kind. All aluminum in color. All the same inner and outer diameters. The only difference is a slight difference in thickness.

So, where do the thick and thin ones go?

I'm assuming that I won't be able to tell much from the old ones since they will already be crushed. Without additional guidance, my inclination would be to use the thicker ones for the drains and the thinner ones for the fills.

Any help would be appreciated.

Thanks, expo.

I had already reviewed these a while back, probably before the part number corrections so I don't have the copper one for the diff.

JD's website did answer the question that the trans washers are the thicker ones.

I just reused the copper one when I did my fluid change. It's the filler plug so what really can go wrong?

Leaks when taking corners or on inclines? Most likely not going to happen if you torqued the plug to spec. and this the washer's second use.
