legitdid the double fluid change on my 2019 chevy 2500 since i didn’t know when it was done last or what kind of fluid and it has 126k miles. she shift so SMOOTH now it’s wonderful it makes me so happy that my truck is happy :3also very glad to know that i won’t have to do this again for a very long time with this stuff. 300k fluid change interval is insane lolmy advice tho: get a good pail pump that lists how much fluid per pump so you’re not guessing and having to check the dipstick a buncha times and a long hose so you’re not having to lift a big 5 gallon bucket into your truck’s engine bay lol

I bought this to do my transmission service on the Allison 1000. Let me tell you I thought I bought way too much initially but ended up using around 2/3 of the pail so this is by far the most efficient method of buying this. The only unfortunate thing is you have to pour it into a separate container to measure it and put it in the truck.

Used this in my 2011 Tiffin with Allison 3000 Trans. This is the recommended fluid so I am hoping for trouble free running. Good price for this product.

This is sold by evey diesel store online for the alison 1000 transmission. I’m pissed. I’ve used castrol for 30 years. I’d recommend them to anyone… until last week. We talked to castrol over the phone. It was the best for the alison. The newest formula. We called castrol 3 days later to ask if it was okay to use in the transfer case as well… castrol says on the second call ” not only is it not okay to use in the transfer case, but it doesn’t meet the requirements for the alison 1000 transmission either. Now I’m the not so proud owner of a 5 gallon bucket of transmission fluid that isn’t usable and castrol won’t refund exchange or even admit mistake. What crap customer service for a long time favorite company.2004.5 chevy 2500hd lly extended cab 4×4
