What to use instead of Mercon?

[razorback]

ok got the bottle out of my garage to make sure it wasnt type F. here is what it says:

meets mercon requirements, and do not use in mercon 5 or mercon SP.

If you had the truck filled at the dealer in the last few years they most likely used Mercon V. They buy the stuff in drums and "use what they have".

If so, I would drain the trans and torque converter and fill with the proper spec fluid ASAP.

So in my C6 what should i be running. I just did a complete flush and filled up with Type F. Is that what i should be using? Or did i screw myself?

It should say on your dipstick. However either Type F or Mercon is FINE in your transmission. Mercon will give softer shifts if that is something you desire.

The problem with Mercon V is that it is chemically incompatible with older transmission internals.

A quick search of the suppliers shows most are still providing Dexron III/Mercon. Some are also showing products that are compatible with both the Mercon and Mercon V spec. Quaker State shows their product compatible with both. Pennzoil also shows a product (high mileage ATF) that is Mercon compatible which would make sense since all our transmissions are considered high mileage. Castrol, Havoline, Valvoline and Chevron all show Dexron III/Mercon as available.

I think Brad Penn is making it. They are rapidly turning into my favorite refinery.
