94 Explorer has decided to not go into overdrive on automatic trans. tried error code reader and I scored 2 hits, DTC 335 and 412.
The chart I found online indicates that the 335 code equates to an EGR voltage not in the range expected in circuit A. It says the 412 indicates z high rpm control issue, again in ckt A. So how do these relate to a transmission that does not go into overdrive? Suggestions please.
