Had a drain and fill on the transmission performed on my '17 Taurus at Quicklane. It was done at 42K miles. The next day I went on a 250 mile trip and got a yellow wrench light on the dash. Having never seen this before I had the wife look it up in the owners manual. It said take in for service, no help there. After stopping for gas, the light went out and remained out until a 300 mile trip was taken, then it returned. Both times were after a hard shifting from 3rd to 4th. I noticed the transmission was starting to puke fluid out the cap so I checked the stick, over-serviced! I pulled out the repair bill and was charged for 10qts ATF and a qt of flush. After some research I found out they should have only put in 5 qts ATF. Went back to Quicklane and they made good on the drain and fill again but took some discussion about "how much" to put in. The technician did not know and was told by the service manager. Point here is be careful when going to Quicklane, training seems to be lax.
