Help Please!94 Concorde 3.3 Codes 12-66-55 Limp Mode

[borninabarn]

Ok techs about ready to take this one to the Crusher.Help if you have any ideas please.This car is still stuck in 2nd(0nly goes 35 wont shift up) All of the shift indicator lights light up after 5 seconds after starting it up and now the speedo doesnt work again.Just got done replacing the valve body with the solinoid and everything attached from a well know good one.New atf plus 4 trans fluid. Have replaced input and output speed sensors,tryed a different TCM(does the same)checked all the wiring that i can,cleaned all plug in terminals to the trans and the 4 by the right shock tower.Have read in another post someone replaced the ignition switch and that fixed his problem.Could that also cause this to happen to this car(he had a code 43)PLEASE HELP WITH ANY IDEAS!Thank you

That sounds like my post.The ing switch might fix the speedo.Does everything else work on the dash? I also hard wired the plugs at the strut tower.I cleaned and cleaned to no avail.As soon as i hard wired it,it worked mint.I don't have the tools at home to check what those codes are so if you can fill me in I might be able to help more.PS: this hot rod is knowen for the wiring harness going green under the rad.Lets not go there just yet.

Everything else works on the dash its just the speedo that doesnt work again(it did before i switched the valve body)Which plugs did you hard wire?there are 4 plugs there did you hard wire all of them?Thanks for the info and how much was the ignition switch?is it just the switch or does the key cylinder come with it as a whole?

Just the 2 plugs that go down to the trans.Can't recall which 2 they are.Easy to follow from the trans up.As for the switch,I would look at it last,it is just a switch, no key deal.You can tell if the switch is bad or lose by stripping the column covers off and moving the switch while the car is running.The switch is on the left side of column,just a box type deal.

check your trans relay make sure you have no ants inside. swap relay with starter one. What are codes 12-66-55??

[borninabarn]

Have not yet hardwired the connectors but will,No ants?The code im really interested in is the code 66!I got that doing the key thing 3 times and the light blinking.Thanks guys!I will keep you posted.

Hey sorry Twisttech! This thing has been sitting in the back yard all winter.Had tons of snow but it is finally looking like Spring here in Iowa.I dont really want to look at the car anymore.I had someone offer me a nice old KZ1300 Kawasaki even up for this car.I am going to trade.Need something new to tinker on.Thanks and Take care!Born
