I've got a 2001 Suburban 1500 with 217k miles on the original engine and transmission. They're both still working great so far, and I'd like to keep it that way as long as possible.
About 80k miles ago, I had a "quick lube" shop change the transmission fluid, and gave them a container of "Prolong" to add to the new fluid. They do that job like an oil change ... they don't remove the pan or change the internal trans filter. No problems whatsoever in the interim, so that apparently worked out OK, but I never realized at the time how much of your old trans fluid remains in the pan (mine is the "deep pan" kind) when all you're doing is pulling the drain plug and letting the fluid run out of that opening until it stops.
The inside of the drain fitting extends above the bottom of the pan quite a bit, so even when the fluid has stopped running out of the drain bolt hole, there's at least a full quart or so of fluid still pooled in the bottom of the pan, along with all the fine particulate dirt/junk that's worked its way through the trans and filter over the years and settled on the bottom. I was REALLY happy to finally get AT that stuff, remove ALL of it, give the pan a good cleaning and replace the filter.
This job is a pretty involved, dirty mess, and the last thing you want to be dealing with once you've successfully removed the pan and pulled the old filter/seal out of the trans case, is some ill-fitting, aftermarket replacement filter/seal and pan gasket. This AC Delco gasket/filter/seal combo is the one MADE for your trans and THIS particular job. If you're doing this job ... just get it.
Mine came packaged on a shrink-wrapped piece of cardboad, complete with GM part number/label, all parts in excellent condition. The filter seal tapped into its fitting perfectly, the filter was a dead-on match for the old OE I removed, and it also easily popped into its new seal with a reassuring, snug fit. The gasket was also a perfect fit on the pan ... I didn't even have to do any goofy tricks to line up the bolt holes ... imagine that.
While removing/cleaning the pan was a pretty time-consuming, messy task, this kit made putting the whole thing back together a breeze. Once I got to the re-assembly part, I found that I was happily tightening down all the bolts and refilling the trans case with fresh fluid within minutes. Highly recommended.
