Been running Castrol ATF dextron 3 for a few years in my trans, would it hurt to switch over to castrol dextron 6? When I had the trans built a few years ago Eric at dynotech told me to run dextron 3, but the dextron 6 seems a bit better
 
This is what I have been running for 3 years now with a bottle of Lube Gard...so ya think I should just stick with this?

Switch to the DEX 6, your not going to hurt anything only help your trans. As i am sure you have read the DEX 6 has better properties and it also with stands heat better. you know heat is the killer for transmissions. Anyways Switch it you have nothing to loose
