DIY Transmission pan drop filter change. Any tips?
Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
Doc, thanks for that...
He is suggesting leaving the pan alone. Running a SeaFoam add then doing a complete flush. Dropping the pan is whats avoided here. I have the kit with the filter and gasket. Since I was going to try this but now its too cold outside...
The transmission accumulates clutch material debris over time captured in the filter.
Transmission flush will not clean the filter.
Any blockage in the transmission filter will restrict fluid flow causing premature failure to the transmission!
Proper maintenance on a 4l60E>>>300k+ miles.
Save a little now, pay a lot more later.

Thanks hummerz...
Agree. my guy is being lazy and wants the easy way for a garage to make some bucks.
Since I already bought the part. Will press him to do it right.
Just did mine a few months ago. Agree with Doc to just disconnect the front of the driveshaft and pull it out of the way. However, there was another thing that I haven't seen anyone here mention; maybe it's only an issue on the Alpha? The transmission shift cable/bracket. Mine was in the way of one (or two?) of the transmission pan bolts. "Possible" to get it (them?) out, but no way to reinstall and torque correctly. Just had to remove the clip at the cable and move it out of the way; not to big of an issue.
Also, I could not get the rubber grommet for the filter out no matter how hard I tried. Anyone have a secret (for the next time I do this)? I ended up leaving it in place instead of replacing it. The new filter felt good and snug in the old grommet, so...hope it doesn't come back to bite me later.
Oh, one more thing: Get a cheap plastic kiddie pool for a drain pan...you'll thank me later!

I just did mine this past weekend. I don't remember a shift cable being in the way, but I agree that for me it is easiest to remove the front drive shaft.
As far as the filter seal, they can be tough to remove. The best way I found was using a cheap harbor freight slide hammer and puller set. $32. The highlighted attachments get threaded onto the end of the puller and spread out the further you thread it on, so you can exert *some* pressure to grab the seal. Then gently tap out. Obviously you need to be careful to not scratch the aluminum. Insert the new seal with "a suitably size socket", per the tech guide. Mine ended up being some metric socket JUST smaller than 3/4".
Hey Guys...
Thanks for all the useful data. I had my man CJ do it at his shop...
He ran into some problems. Probably cause he is not a member here. Anyway its done and the truck is happy. Had him change the engine oil as well as a good trans flush with the proper equipment.
Its running nice now and ready for a nice road trip to Florida.
