we just went to a transmission place for a diagnos on our 1997 Ford Expedition. They gave us the codes 1120, 122, 133 Wondering what each code means, also he suggests taking out the transmission to give a definate diagnos, but in the short term has told us that the timing sensor needs to be changed out and said it would be wise to put in an addiotional cooler to the radiator to help cool the transmission. Can anyone give us a bit more insight on this information that we have been given? Explain what they mean and maybe give us ideas of what we really need to do.
Thanks
Terry
