Do we have an updated chart if fluids that reflect improvements since our trucks were built? Like my owners manual from 2001 recommends ATF+3. And it seems that ATF+4 is now recommend. Be nice to have a consolidated chart for all fluids that reflect current advances in fluid technology.

I'm all for this. The only way I know is contacting the dealer, and auto parts store I actually trust or another thing I do is check the recommendation for my vehicle from Amsoil. Not for only using their product, but using it as a comparison to other products. Then buy where I feel best. Outside of that, it's been a hit or miss for me.

Go to Amsoil.com and look up your truck. It will have all the recommended fluids listed along with the amount needed. I do Like anoldbiker does, go look there and compare prices (and I am a dealer). ATF+4 is about $2 a quart cheaper for Mopar brand at Walmart than Amsoil is at the counter.
