Recommended RV ATF for Towing?

Jason Oldfield · 01-20-2016, 04:53 PM

Hey Guys,

Quick question - is there a general "best" ATF out there for use in RVs when towing? I have a 34' Winnebago Itasca Suncruiser that I tow my 24' enclosed trailer with. It's a Workhorse chassis, so the service manual states that I should use Dexron III, but that has since been superseded by Dexron VI.

I'm going to change the tranny fluid, and am wondering if I should just use any brand of tranny fluid that meets Dexron VI specifications, or is there a known "best" alternative for this type of application? That said, unless there is a specific recommendation, I will use a brand that supports our sport (Lucas Oil, Red Line, Amsoil, etc.) rather than just using a generic brand.

Thanks in advance!

Jason

Amsoil has Signature Series atf that is a replacement for Dexron III. It what I use in my Dodge tow vehicle and have zero problems. However I change it every 30,000 miles.
