My 1998 Ford Taurus Transmission went out recently after having a rear brake job, and a tune up. A local Transmission shop rebuilt the Transmission for $1700.00. I didn't realize, that used parts was used to rebuild this transmission. This was told to me after I took the vehicle back to have checked, after the check engine light came on. The Mechanic told me the that the computer texted the code as P0340 "Cam position sensor out of range." He further added he wasn't sure what this code meant, and suggested another shop to handle the matter (a friend of his). Also, I am concerned that when I'm driving and accelerates to 40 or 50mph the car seems to want to lose power, but doesn't cut off. For instance I'm driving along, and the pressing the gas, and the car seems to decelerate on it's own. I told the Mechanic of this concern and he said that the only thing he could figure out is the used valve body that was used to rebuild the transmission, came from another vehicle, and it was probably programmed just to fit that vehicle. He further stated that he had no real concerns, for the ID numbers matched, making the valve body compatible. I have real concerns about this situation. It's been almost two weeks, and the deceleration continues to get worse. Also, is it usual and customary to utilize used parts when rebuilding a transmission? For $1700.00 dollars? Please weigh in on this, I need some answers!!! Thank you kindly

Cam Sensor on the engine. Common on a 3.0L Vulcan. May also need the sychro assy that it mounts to. A used valve body??? Well... if it was in better condition than what you had, and he dis-assembled it, cleaned it well, and put it back together correctly then I wouldn't worry, but then again, you have a problem.. I'd check that trans. fluid and make sure it's the correct level. If you were to mat the gas when it starts to decel, what happens???

Thanks for weighing in Tbird! To answer your question, once the car starts to decelerate, I press the gas pedal then after a slight hesistation it continues to drive along. I think, what bothers me the most, is that 2-3 weeks prior to my Transmission failing, I noticed this same behavior in my vehicle. I'm not sure what to do,other than take it back to the transmission shop that repaired it. Albeit, I did, and he said no worries. Not sure I'm trusting him altogether, since he rebuilt my transmission with used parts. Thanks in advance for any suggestions.

If you still have the check engine light on and have the Cam Sensor code, take care of that first. There are other threads relating to it's replacement.

Here's one... 2003 Ford Taurus

Bump!!!

Thanks Tbird for your helpful insight. I will obtain an estimate for repair of cam sensor. I am; however, still concerned that a used valve body for installed in my transmission, and that this is causing the deceleration. Has anyone had this experience with their vehicle, after a rebuilt transmission installation?
