stealership?

Just thought I'd call and see what the stealership would charge to change the tranny/differential fluid. $210 for the tranny fluid and either $190 for limited slip or $140 for other differential. I can't remember how I know whether I've got a limited slip or not. Is it in a code somewhere?

If the diff tag is still there. There will be an 'L' in the mix. Usually in between the axle ratio numbers.

I agree, God is good! No I'm not letting the stealership do it, just wanted to see how much of a rip off it would be. Can anyone tell from my differential tag what kind I have? I can't make out any L anywhere. Also, I'm going to buy tranny fluid, rear end fluid and a tranny filter. What type fluids and where can I get the tranny filter. Lastly, I need silicone for the rear end cover, what kind?

Thanks!

It's not a Limited Slip, so, you'll need to get the axle code from the data plate on the driver's door post.

This'll help you decode the tag on the diff.

And this'll help with the fluid change in the tranny:

BTW, it was written for a SouperDooty but the procedure is the same for an OBS.

You said by looking at my axle tag it's not limited slip but accoirding to my axle code "D5" it is a 4.10 limited slip. How in the world do I know for sure?

The diff tag has no L on it. Your door tag says D5, an LS. I, personally have never trusted either. I open the diff, count the teeth on the ring gear and pinion gear, then I know what I'm running. I'd drop the diff cover, let it drain, and as it's draining, go get what I now know it needs.


The easiest way to tell is to drop the cover and look. If it's a open diff, you'll see the side and spider gears easy enough. An open carrier is just that, open to the side and spider gears, no positive drag applied at all. In a LS carrier, you'll either see an enclosed carrier, or steel/fiber disc plates on either side of the side gears. Side gears are on the 'sides of the carrier, and are what the axle shaft splines insert into. The spider gears are what the cross shaft inserts through. The spider gears are what walk around the carrier, leaving you with one tire not spinning while the drive wheel has no traction, spinning in the air.
