Expedition transmission problems
I have a 2003 expedition, ran good and drove good
buy it started to smoke, so I pulled the battery and
removed the heads and re done them, put it back
to gether and it starts and runs good again but it
would not move when put in any gear, then it
moved back when in reverse, and nothing forward
untill the RPM was gotten high then it went forward
an now it only goes forward even if the selector is
in neutral or reverse, I would like some ideas to try
before I change the transmission if any one can
Sounds more like an electronic issue, it is possible that the solenoids got gummed up while it was apart, I would take it by a good tranny shop first. They may have to hook up some test equipment to see if the tranny responds to manual inputs.
O never took the transmission apart and only took stuff of the engine, so how would they get gummed up, the battery was out for a while and was wandering if there were some sort of reset pattern to reset the computer
You could try and change the trans fluid and add some Lucas transmission fix.
Ok and yes that could have lost all of the computers presets, removing a battery completely from a later model rig has deleterious effects on control systems, if you can't find a tranny shop that can reset the controls then your stuck with the dealer and most likely a system reflash.
