Opon leaving work for the day my second gear synco in my transmission completely failed leaving the parking lot. Therefore I no longer had 2nd gear. So I took it to a Ford dealer where they where to fix the problem but in turned fix 2nd gear but messed up my reverse synco gear now. The car has been in the shop for almost 4 weeks and Ford wont make a surplus of part for this transmission that the parts needed are on back order until April 20th 2015.
According to my Ford dealership, the synchronizers between 1st and 2nd bears failed. I have had several issues with this transmission previously, causing the car to fail to shift while accelerating. This is incredibly dangerous, as failure to accelerate while merging into traffic would have been catastrophic. Thankfully, I was in a parking lot when my transmission failed.

Noticed a transmission leak while rotating tires. Took it to my Ford dealer, who examined the leak and informed me that the forward transmission seal failed.

Dealer said this is happening to many Mustang transmissions and there is a service bulletin.
