Hummer H2 2005 - Transmission Fluid and Filter Change

This the Big One ! 🎈
The Hummer H2 was produced between 2003 - 2009, so now many of them have over 100K miles on the clock.
Auto transmissions are very complex systems, with many moving parts. Transmission fluid lubricates and prevents overheating, but burnt-out or old contaminated fluid, choked filters, leaky seals, metal fragments and microscopic debris can cause irreversible damage.
We do of course, regularly check the transmission fluid levels, but as you'll see there is a little more to it than just the "level"
Start by watching this video, then by doing the work yourself you can save money in the long run, save your transmission and you'll have the satisfaction of knowing the work has been done properly.
On the subject of "flushing" here's a quote from GM Service Bulletin 04-06-01-029J "It should be noted that analyses of returned parts that have been exposed to these aftermarket 'flushes' show indications of potential damage and shortened durability shortened durability"

The pump came in. This thing is massive!!!! JohnDow fluid extractor. Holds 1.7 Gallons or 6.5 liters. Will work on it tonight.

Excellent video hopefully I can get the same results you did. The attention to details you covered is top notch information and is very much appreciated. Thank you for this video.👍😁😎👌

[@myamazinglittleworld5673]

Bro thanks so much 🙏 for these videos, keep bringing them, we don't have lots of videos out there showing up how certain things get repaired. Thanks

[@hummerfixes]

Thank you for your comment, I'll try to keep them coming 👍

Got the new pan on, I used a transmission jack to lower the pan. 4 quarts total came out. Have put in amsoil and could feel an immediate difference.

[@longlivechina7538]

Just ordered the pan, a gm oem massive magnet, will be starting on this process in a few weeks.

[@hummerfixes]

You may find you don't need the magnet your current pan should have one, the one I bought is stuck to my office desk at the moment.

[@longlivechina7538]

I took off my passenger side rock bar and steps. It makes it so much easier to get under the truck. I use a mechanics roller too. Really don’t notice its off. I haven’t put back on the transmission protector either.

[@hummerfixes]

👍

[@longlivechina7538]

On 8 new gallons of Amsoil and wow shifting is incredible. Will do two more and it will be complete .

[@longlivechina7538]

I put amsoil in the transfer case, great result

[@albertorangel2940]

Again and again. Excellent video

[@abadialsharif2047]

Thanks so much man u hocked me up 🙏🏽🙏🏽

[@advancedhittingtraining8233]

Why is the oil pan replaced? Is that a nice to have or mandatory during the ATF oil/filter change? Great video!

[@DroneFixes]

Thank you for your comment. The choice to change the oil pan depends if you want to add a drain plug. To perform the progressive series of fluid changes it would ease the workload considerably. Sadly it's not possible to drain all the fluid in one visit without special equipment, or should I say it's not easy.

[@longlivechina7538]

Whats the seal do?

[@longlivechina7538]

My gasket that came with the filter leaked I had to reinstall with felpro fingers crossed no issues

[@joecrump5354]

Another detailed and extremely helpful video. Very much appreciated. Regarding the seal removal, I used a quick and easy homemade tool of a 12"X1/2" threaded male pipe (to screw into the seal), attached to a 1/2" female t-section, with a 4"X1/2" male nipple also on the t-section for tapping down.

[@longlivechina7538]

How bad were those specs of metal?

[@hummerfixes]

Nothing excessive, similar YT videos showed similar results, normal for the mileage probably.

👍👍👍👍🇩🇴🇩🇴🇩🇴

[@longlivechina7538]

The new GM magnet is much beefier and stronger than old magnetic. Will say made in china, but its the right one.
