Teflon Grease?
 

Does anybody know an alternative to Teflon Grease so I can grease the slip yoke? You can only get this at the dealership and I'm sure you know about the dealership prices. I've heard that it's important not to use the wrong grease because it will mix with the transmission fluid and could cause damage maybe?

I buy it from the dealer too.

I've heard that Teflon grease is synthetic grease. I went out and found some synthetic grease but its exclusively for brake calipers. It says its a specially formulated grease containing molybdenum disulfide, graphite, and TEFLON.
