Too bad the TSB does not give the solution to the problem.
I didn't realize that you bought the car that short a time ago. If you bought it from a dealer, return to them and ask them to rectify the problem and explain that you understand that Ford has a TSB on these trannies. You wish that Ford will pay the tab, parts and labour.
If the dealer balks, then ask for the number for their Ford Canada service rep (or whatever Ford calls them) and speak to Ford directly.
If you bought the car privately, you may have more problems. Most makers reserve goodwill repairs for original owners or dealer-bought cars. But, that does not mean you should not try and have the problem fixed on Ford's dime.
There are implied warranties of use when you buy a used car from a dealer, but they can be tough to get action on. Also, you may have bought the car "as is." That is not "all encompassing" but it does tilt things in their favour.
Did you have a PPI done on the car? If so (and please tell me you did...) then you might wish to speak to the original mechanic and ask why the problem was not spotted then.
Don't get all PO'd at the dealer, or they will do nothing for you, ever. Make friends with the service manager and explain that you feel that the car should be repaired at Ford's expense. Don't ask the dealer to pay until Ford says no. Make him your ally "against Ford."
