Default 4L60 pump to case gasket question
I just finished assembling a '93 model 4l60 and after I pulled the valve body gaskets from the kit I noticed another pump to case gasket slid in there after I'd already installed the pump. I didn't realize there were two gaskets in the kit and now I'm wondering if there are differences between them. The ATSG manual is pretty good about pointing out differences bwtween the various models and I don't see anything about the pump gasket. Anyone know? Pete?

Thanks!
Dan

Dan,
82 and 83 only used the gasket without the approx 1 inch bulge.
Use the gasket that has the "bulge" for your car.

Hmmm, not sure I know what you mean by "1 inch bulge". If I posted a pic of the gasket I have left over can you identify it?

Thanks for the quick reply!

So just to be clear, the pic I posted is the 82-83 gasket? The other is in the assembled transmission and I'm just trying to avoid pulling the pump back out, although that would be easier now that later!

Yes. The pic is 82-83 style. If the other gasket is installed, you are good to go.

Excellent - Thanks for your help, and I've appreciated the help you've provided others on the forum regarding the auto transmissions. I've learned a lot from those posts too.

Happy Holidays!
