🔧 Mobil Delvac Syn ATF, 1 gal: The Ultimate Synthetic Automatic Transmission Fluid Solution Review

Not an ounce of foil film under the lid. It was tightened, with the strength of a 3-year-old girl. I wouldn't buy this. Correct me if I wrote something wrong

Used this to replace the Allison 6 speed transmission in my 2008 Silverado 3500HD with TES-295 fluid from the Dexron VI factory. The truck is much more responsive and normal gear changes are so smooth they are almost imperceptible.

I switched to this latest transmission oil and filter change with Transsynde after reading all the great reviews and it did not disappoint. The transmission worked like never before, hauling our toy dump truck fully laden with water, fuel and RZR. Definitely a new customer here. (2007.5 2500hd LMM)

I changed the fluid in my Allison 3000 MH Van due to a leak in the control box gasket. What I didn't expect was that the transmission shifted much better after all the old was flushed and refilled. With only 25,000 miles (nearly 11 years) I didn't think it would have such a significant impact on performance. I ordered 3 more gallons and the seller was great. Return no problem. Many Thanks.

These are Allison's specifications for Duramax transmissions. No matter how many trucks are equipped with Duramax, it should have been a lot easier to find one.
