hello I have a 2004 ford focus with 2.0 single port engine, with a 5 speed. My problem is the transmission. It started to be hard to shift in the gears when it was at normal operating temps. I changed the fluid but didn't help. Now it will only go from 1st to 2nd. Cannot get it to move over to get 3,4,5 or reverse. Not sure what the problem is. Any help would be appreciated. Thanks in advance
