Transmission Pan - Deep or Standard?

The 4L60E trans. pan in my 03 Envoy was a little over 2" deep and took the deep filter. Have you actually checked some of the online parts houses, like Autozone to actually see if both filters are listed? If in doubt buy both and return the wrong one.

I think you better check with another parts store because a good one should know because GM is not likely to but different pans in the same chassis and application (like 2001 blazers) if they change then it is likely to be in different applications, not the same car. .

No, that parts person was right. There are different pan depths in those transmissions in the same applications. I have run into this numerous times when doing trans services on these vehicles.

I had the same problem last week when I changed the fluid/filter on my 02 silverado 5.3L engine. The pan looks big but I don't know if it is the 'deep' one. The parts guy @ NAPA asked me the same question, standard or deep. I went with standard. After I ran the truck for 50 miles, I again pulled the plug and drained the fluid, it took 3.5 quarts to fill up to normal. So is this a standard or deep??? Ian or Gary (TS)??
