1993 Chevrolet k1500 with a 4l60e
THIS is a proper gasket. It's a thick rubber gasket that doesn't flop around or turn inside out when trying to put it in to place. Nothing like the cheap cork gaskets that come with filters or the thin rubber ones that flip flop around when trying to put them in place. This is a proper thick gasket. I used it on a 1993 Chevrolet k1500 with a 4l60e.

Amazing gasket
This is so much better than the duralast branded gasket from autozone. Its much thicker and not as flimsy. Transmission is not leaking anymore and I'm happy.

This is a time saver and well worth the nine bucks!
Just got this for my 2004 GMC Yukon to do a filter/fluid change. I didn’t know if I had the large filter or the smaller one (there’s two different sizes) so I went to the auto parts store and bought one of each figuring I’d return the one I don’t need. That’s when I discovered that the filters come with the gaskets as well sooo, I figured I would return this felpro and get my 9 bucks back. Well the day I did the fluid change I was going to put the pan back on and the pan bolts went into the pan and into the gasket but would slide out as soon as I turned it over. That’s when I recalled another reviewer said he liked this because the holes in the gasket were a little smaller so he had to “thread” the bolts into the gasket which was great because it made it way easier to put the pano e knowing the bolts were holding in in place. Doing the fluid/filter change o these GM products is not an easy job, made worse if you’re at home, on your back under the car! I wouldn’t have been able to put this back on had it not been for the smaller holes in this gasket. So don’t use the rubber junk that comes in the filter kit. Spend the $9.00 and save yourself from the headaches of trying to line up the pan, bolts and gasket under the car on your back!

Chevy Express 1500
I always use Fel-Pro gaskets, they're the best. Perfect fit for an 04' Chevy Express 1500 with the 4L60E transmission.

Fits correctly and holes line up. Pleased that the gasket came flat on carboard and not rolled up in a small box. Good quality material and not thin.

Cam in a huge box, way too big of box but came undamaged. I don't know maybe sandwich it between two pieces of Masonite instead. It said it was for a 700r4 which is the same pan as a 4l60e. Worked very well. Bolt holes were just the right size that I could use a bolt in each corner to hold gasket during pan install. So didn't need adhesive.
