Re: 93 Escort auto-tranny not up-shifting
If you can afford to do so, I would suggest taking the car in to have the transmission flushed... and I would watch when they do it. I just don't trust those guys sometimes when they get that machine out!
WHen you changed the fluid before (and it was dirty) you left behind lots of dirt fluid in the cooler and other parts of the transmission. Once you have completely eliminated fluid as a cause, then move on to the more complex stuff.
You said the fluid was very dirty when changed... was this the first time in 14 years? If the tranny hasn't been cared for, it could very well be damaged. Hopefully cleaning it up will do the trick.
