Re: Antifreeze in transmission 2010 Duramax??
Here's another interesting fact about the new GM 10L-1000 10 Speed Allison branded trans, it does not have a dip stick and has so called Lifetime transmission fluid. In order to change the fluid you must pull the pan (won't that be full with a full trans). To refill, remove a plug from the side of the transmission and fill to a specific amount, then when the trans is up to a specific temperature top off and replace the plug. Wow, that sounds like a great improvement, I guess it was to easy just to replace a spin on filter and add the difference lost by the filter replacement via the dipstick.

No doubt the Allison 1000 6 speed used with the Duramax was getting long in the tooth and at its max capacity as far as torque input was concerned. What is a real shame is that GM passed on the newly upgraded Allison designed 9 speed to push their in house 10 speed. I am sure it all had to do with money! With that said and to be fair I don't believe any automatic transmissions is perfect when they are first introduced and I am sure the new 10 speed will fall into that category. Check out the issues with the new GM 10 Speed/Duramax combo's: https://nextgendiesel.com/blogs/transmissions-101/transmissions-101-allison-10l1000-problems-solutions-upgrades At this point if you have this new transmission keep a close eye on it and get it in for warranty service BEFORE the warranty expires. If you plan on keeping the truck past the warranty you may want to consider an extended warranty or possibly perform some upgrades. Best of luck whatever path you take!331Views0likes0CommentsRe: Antifreeze in transmission 2010 Duramax??
The new transmission that will be going in the Dodge will be made specifically for the Cummins platform. (this was announced some time ago and should happen some time in 2022. If your interested here's an article you may like to read: https://www.autobison.com/2020/02/which-new-transmission-will-ram-pair-with-the-cummins-diesels/ The 9 speed was orginally going to be used for the Duramax but GM passed on it in favor of their own new in house 10 speed transmission. When GM announced the new 10 speed I was curious why they needed so many forward gears. My 2013 Duramax worked just fine with the 6 speed an would climb a 6 percent grade at 70 mph pulling a 10k trailer and never come out of overdrive. Personally, I did not believe believe the hype that GM said about their new BRANDED Allison transmission and actually called Allison to ask them about it. I was told by them that the branding is noting more then an agreement between GM and Allison, though Allison did lookover the design then did not have a hand in it nor do they have any involvement in the building of the new 10 speed. Not the case with the 6 soeed 1000, even when the building was supplemented to the GM plant do to the demand, Allison employee's were involved in the build. Not so anymore... Please don't take these post as an assault on the new GM 10 speed, I just didn't want to be a guinnie pig for it especially after reading the problems with the co-engineered Ford-GM 10 speed used in other applications. I hope for all those who purchase this new tranny it proves out. I guess we shall see.334Views0likes0CommentsRe: Antifreeze in transmission 2010 Duramax??
The Allison 1000 transmission that is used with the Duramax is probably one of the best heavy duty transmissions ever made and unmatched in any other brand truck, it was the primary I purchased the Duramax over the Dodge or Ford truck. I have a friend with a 2013 3500HD with about the same mileage as you. He had the same problem you did at about 200k. He replaced the radiator, flushed the trany and replaced both filters and refilled with Transynd and the truck hasn't skipped a beat. Since his mishap he as put on an additional 100k on the truck and this thing tows a skid loaded 3 to 5 days out of a week. You caught the problem quickly and did the right thing. I think your good to go! Its sad GM decided to go with there new 10 speed "Branded" Allison in their new trucks, it's really not an Allison since they did not build or engineer it. If Dodge gets the new true Allison 9 speed this will be a game changer for them and I think many will jump brands to get it. Anyway, Cheers, glad to see your back on the road again!334Views0likes0CommentsRe: Antifreeze in transmission 2010 Duramax??
ivbinconned, don't give up just yet. The issue of a failure of a transmission cooler in the radiator is a common problem for GM. The real issue how long did it go before you discovered the problem. In many cases you can simply replace the radiator, have the transmission flushed and the fluid replaced and you may be good to go. This is something you may want to consider before you just give up and purchase a transmission rebuild. Ultimately if the transmission has been toasted you can have a GM dealer replace the trans with a factory rebuild and you will get at 3 year 100k warranty to boot. Do your homework before you give up. You have lots of options!335Views0likes0Comments
