I have a 2001 Dodge Dakota 4.7 engine automatic transmission and when the overdrive is on it shifts in and out of overdrive all the time What should I do? I went to autozone and had a diagnostics run and it read that the PO734 was the problem and gear 4 incorrect ratio How do I fix this?

First check and make sure the fluid is full. The most likely cause is a failed solenoid pack. Circuit codes normally mean something electrical not mechanical has failed. The solenoid pack is on the outside of trans pretty easy to replace.

Check the input shaft and output shaft speed sensors on the transmission. One is likely bad.
