I have used this shop in Ventura on my Ford truck. Complete rebuild, not cheap, but very good work http://www.dmctransmissions.com/
Have not heard good things about Leons transmissions
You could ask the place you had the alignment done at. IDK if they do transmission work. That shop does work on several "classic" cars as I suspect you saw when you had your alignment done.
My experience on the Transgo kit...go 2 washers. 3 is like stun unless that is what you are looking for. Just my $.02
