2005 Dodge Ram 1500, began shifting hard, then when driviing

Customer Question

Customer: 2005 Dodge Ram 1500, began shifting hard, then when driviing around 40 MPH keeps shifting (rpms go from 1500-2000), shifts hard when decelerating. Check engine light came on and got aP0068 code. COuld the TPS cause the tranny to act weird? FLuid color is fine and no smell?
JA: Thanks. Can you give me any more details about your issue?
Customer: Got a P0068 code. the Transmission is shifting erractically in the mid range (around 40 MPH) and then downshift hard during deacceleration. Could a faulty TPS cause the tranny to act up? FLuid level is fine, color is good and there aren't any burn't smells coming from the fluid

Hello and welcome. My name is ***** ***** you for visiting the site, I will be happy to assist you today.


The TPS can definitely effect the shifting of the trans. If it is bad, (or the circuitry) that would have to be repaired before any diagnostics for any shifting problems.


I can get the test instructions for it and put it in a PDF file, (it is rather large) and send it to your email address for as little as possible.


You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it, Thanks
