Make Sure You A Prepared - 2014 Silverado
So, my 2014 Silverado ( WT/5.3 ) needed a transmission service. This worked perfectly. Fit without issue. Great quality. If you have not done this service before, ALERT removing the pan is a complete PITA. Thanks, GM Engineer, for attempting to make it impossible for the DIYer. Sorry, it's not my first time with wrenches. 2 out of 4 wrenches. It is not tricky; it is just complicated because vehicle design-exhaust blocks drop the pan. My other advice is to replace the factory pan with a pan with a drain plug.

Great product for a great price
Perfect fit. Bought one for a 2014 and 2018 1500 Silverado 4x4. They both worked perfectly. Very good price for the quality. The gasket fit perfectly for both transmission pans. Very happy with this product.

Wrong Gasket
The gasket was wrong for my application, but the filter was correct and my gasket was reusable.

works well
The filter snapped right in place. I didn't need to use the gasket, as they are reusable. I change the filter every 30-50k miles for maintenance.

I purchased this filter twice already, and will be buying a 3rd soon. I service 3 2014+ GM trucks, and they all have the 6 speed. The filter is very similar to OEM quality, and the gasket is just as good as OEM. Now, even watching all the tips and tricks on Youtube, I was unable to remove the pan. However, if you get a ratchet strap over the Y pipe and the crossbeam, you can ratchet the exhaust down closer to the frame, and it will allow the pan to drop enough to shimmy the filter out and replace it. The vehicles I did this on have 180,000-250.000 kms on them, and did not hard the exhaust. This is also a good time to align the gasket in the pan so it is easier to put back up once you have replaced the filter and cleaned the fluid out of your pan.
