Someone correct me if I'm wrong but the Focus has a sealed transmission. There is not a pan to drop and a filter to replace. I had my oil changed at a Quick Lube shop and they tried to sell me a tranny service for $120.00. I asked the guy how much tranny fluid it takes and he said between 10 and 20 quarts. I asked him to look it up and he couldn't figure out why there was no filter part # and that it only holds 6.9 quarts of tranny fluid.
