My 05 is in the shop for the third time for a automatic transmission leak. First time Ford said some cars were overfilled from factory and were discharging so they drained some oil out and sent me on my way. Well a puddle appeared on the floor of the garage. Took it back for the second time Ford said it could be a bad solonoid valve they relaced it and sent me on my way again. Couple of months go by did a little hard driving and what do you know the puddle reappears back on the floor so back to the dealership I go. This time they are going to replace a valve body in the transmission at least that's what I thought they said I'll know better tomorrow.
One other problem I found was rear brake calibur was leaking and had to be replaced.
Also the front of the leather seats near the floor leather had become disconnected from seat there is a TSB out for this I have a friend with a 05 with the same problem here is the TSB #
