Allison 10L1000 10 speed tranny Thanks to Youtuber : https://www.youtube.com/@JoesCarSmartsNY I learned that for some F'd up reason Allison leaves about 2 gallons in the pan after you've "emptied" the trans fluid, so.... knowing this allowed me to head off an awkward situation laying on my back, I really did not want to take a "tranny fluid shower". I made a little wooden platform for my bottle jack and after slowly lowering the pan a few inches I used a vacuum tank to suck all but a few ounces of fluid out of the pan. This worked beautifully. Almost no metal sludge on the two large magnets after 60,000 on a light RV towing pampered 2020 Chevy 2500 diesel pickup. Trans fluid had darkened considerably but still smelled "good". Ya gotta love Youtube, a video posted voluntarily made the job easy peasy, lemon squeezy!

Well there's your problem, lady! Ya need a longer one, and mix it up with a right angle tip! Just a few squirts from a small gun, little one moves in and out so much better, feels good compared to the old big one with the short length hose.....

Thanks Corey, Google and several parts suppliers didn't know! When the time comes I believe I could do this maintenance. Shouldn't be a problem monitoring temperature to get fill correct.

Is there an internal filter on the 10L1000 10 speed auto tranny? If so, anyone know the part number?

New 2020 Silverado 2500 diesel, newly retired, bought truck to tow a travel trailer. I've been a GM customer and amateur mechanic for over 50 years. I had not driven a 3/4 ton truck for decades, when I test drove a new 2500 I simply was stunned by the ride quality, to say the mechanical engineers have made improvements would be a world class understatement. The power, ride quality and tow features (mirrors and cameras) sold me within weeks of shopping. The size is a little off-putting but after only 8 weeks I have compensated for parking and maneuvering a very large pickup. The truck draws some jokes about its size but I absolutely love the towing performance, it is a worthwhile trade-off for me.
