OK, I just got my car back from the shop with a completely rebuilt rearend. Including a new Zexel posi differential with 3.42 gears and all new bearings. Now I have to get the tranny gears. I know that I need the 15 tooth and the 41 tooth. I have a good GM part number for the 41 tooth but does anyone know the part number for the 15 tooth one? I have done searches but come up with weird part numbers.

I am going 50 MPH now and my speedo says about 65MPH.

 

15 tooth - 8642620
41 tooth - 25513048

 

I got a 41 tooth out of a tranny that I don't need....pay shipping and you can have it

e-mail me at ardaryjm@i-mef.usmc.mil

 

Don't even both with part #'s for speedo gears. If you order them from gm parts direct like I think you are they'll be more expensive with shipping than just paying dealer price.

 

Take your part #'s to your local GM dealer, wait 24 hours, and get them cheap

 

I looked up those numbers at GM parts direct and they we're both a little over $3.00. I am going to buy some turn signal lights from them so I will just throw them in for good measure.

 

Right, now include the shipping which is gonna be like more than twice the price of the gears alone and they end up being more than dealer price. Shipping is where they jip you.
