I have type "U" trans code with 14 bolt trans pan cover, dipstick says mercron, I have read in other places that folks say use mercron 5.
just left autozone for the fluid and on the computer it said "do not mix mercron with mercron 5 or damage will result"
Can someone clear it up...i bought mercron, but am scared to put it in til i know for sure...
If you are adding I would put Mercon 3 in it. Just playing the odds here as it more than likely had 3 in it.
If you are changing it and flushing the system and TQ then put Mercon 5 in it.
Autozone are idiots. Ford has put out a bullitin to all Ford dealers. Merc 5 does and will work in a trans that used to run mercon/dex 3. It will not hurt the trans or it's components.
