is a 4R70W not an AODE.
You are definitely right, now it is to my understanding that the 4R70W models are Automatic OverDrive Electronic transmissions (AODE).
Now, is there a transmission control module or some type of electronic that would be directly related to the overdrive or 4th speed? Overdrive is not kicking in, I believe that 1ST, 2ND and 3RD speeds are clutchpacks, but 4TH speed (OVERDRIVE) is a band. Am I correct?
Thanks in advance!
