Allision Transmission Oil Change
I have a 2011 Silverado Duramax/Allison transmission and having trouble locating exactly I need to do a 30K Tranny Oil change. Anyone have recommedations on what oil to buy (assuming synthetic), how much of it is needed and what filter to buy. I've looked already on dmaxstore.com but I was looking for specifics for the new LML package. 2011 and 2012 models.

Transynd or one of the equivalents (Amsoil and Castrol both make them) Basically if your just changing the spin-on filter you will loose less than 1qt. They dont require the internal filter to be changed till the tranny needs a rebuild but it really wont hurt to do it and its cheap. Without doing a full flush and fill you will need about 2-3 gallons to drop the pan and change the filters, a full flush can take up to 5. Your truck probably came with synthetic in it already

Your fluid coming from the factory is going to be a dex 6. What fluid to run gets a lot of debate here. Allison recommends Castrol Transynd for your tranny. AMSOIL makes a direct replacement to Transynd called Torque Drive. Though some find this not to be the same because it is not certified by Allison, AMSOIL made Torque Drive by back formulating Transynd so the two fluids are the same. They recommend Torque Drive an all Allison transmissions. AMSOIL also makes a replacement to Dex 6, this being Low Viscosity ATF. I prefer Torque Drive over this based on the Allison recommendation.
The total fill on your tranny is 12.7 qts. There are several ways to do what you are looking for. Some will do a drain and fill, change the spin on add about 8 qts of fluids then do it again in about 50k miles. Others will drop the pan and change the internal to do this, I would have 3 gallons of fluid on hand as you will need around 9-10 qts. Again folks will do this service again in 50k. Lastly, their is the hoot flush. This is a manual flush of your tranny where basically you disconnect one of the cooler lines, then start the truck and have someone pour new tranny fluid into the dipstick until new fluid comes out the cooler line. There is a DIY here that gives you the exact steps.
I carry AMSOIL products and either Allison or WIX tranny filters. I can save you 25-35% off the retail price you see on the AMSOIL website. If I can be of assistance, don't hesitate to ask.

I think Transyn is the best bet.. But if u want zero warranty problems from your GM dealer run Dex VI till warranty runs out ..Then do what you want.. Just my thoughts

Dex 6 is syn......Trans Synd is also syn but group 4 base oil and can handle cold/heat slightly better. Chevron makes a great fluid called Syn Trans HD....it is not TES 295 cert. though. Chevron will not pay the fees to Allison however they do make the Deere fluid that is certified. I think Dex 6 is just fine and the Castrol has only a small edge in a little lower pour point. For every gallon of Tans Synd made they pay a fee to Allison which only makes it more expensive. The Cognis brand is TES 295 and is simply Chevron Syn Trans HD just rebranded and cost about 8 bucks more per gallon to pay for the cert. Since you don't change the fluid that often I would just bite the bullet and get Trans Synd.......But there is not a whole lot of difference between that and Dex 6......but Trans Synd is better head to head just not by much. Funny thing is......DEX 6 IS NOT TES 295 OR TES 389 FOR THAT MATTER!!! THAT IS A ALLISON HD EXTENDED WARRANTY/DRAIN INTERVAL SPEC.

Factory fill is conventional Dex 6. Id go with Allison TranSynd. Buy the Allison brand spin on filter. You can go to the Allison website to search for a dealer in your area for the spin on filter & TranSynd fluid. Or buy online.

No reason to use anything other than the Dexron VI while your truck is under its drivetrain warranty for the first 100K miles. Allison's recommended change interval is every 25K miles which is overkill with a synthetic but it is what needs to be done to protect the warranty.
First Allison external filter change is at 7500 miles and it is the filter only and not the fluid. Allison brand filters online are around $10 each plus shipping.
