Ok so…. I searched the threads and found very little on my problem. I put in a new rack and pinion along with ball joints in my 05 Dakota 4.7 with 128 k. After the work was done, it started to give me CEL lights. I had it scanned and it showed the p0700, cam shaft sensor, and misfire in cylinder 8. I went to O'reilly's and picked up a cam sensor and a crank shaft sensor. After a little bit of work, I had both of them replaced. While I was at it I changed the oil. I took it for a test drive afterwards and the problems started. Whenever I went to go into overdrive the truck now "bucks". That is the best way to describe it. Its like it is trying to go into overdrive but it kicks right back out. If I don't throw it into overdrive it will speed up just fine. Any thoughts on why it is doing this?

 

Odd. Do you think any wiring was pinched or damaged during repairs?

 

did you use OEM cam and crank sensors? many aftermarket ones give problems.

 

Agreed. If the sensors from O'Reilly's are aftermarket and not OEM, they will more than likely cause problems as has been reported numerous times here in the past when aftermarket sensors are used on these engines.

Regarding the overdrive, had the battery been disconnected during any of the services? If so, the powertrain/transmission control modules may have been reset to "factory" status and therefore "unlearned" the 128k miles of wear and tear inside the transmission...If that's all it is, it may just take about a week of normal driving to "re-learn" itself while it figures out the proper forces to engage/disengage the worn clutches, etc.
