The speedometer and transmission issues in a 2003 Pontiac Grand Prix could be caused by a malfunctioning vehicle speed sensor (VSS), which provides speed data to the speedometer and transmission control module. Additionally, a faulty wiring connection or a blown fuse could disrupt the signal. Another possibility is a problem with the transmission control module itself, which could prevent the transmission from shifting properly. It's advisable to diagnose the issue with a scan tool to check for error codes related to these components.
The odometer and speedometer not working, along with transmission shifting issues on a 1995 Ford Bronco, could be caused by a malfunctioning Vehicle Speed Sensor (VSS), which provides speed data to both the speedometer and the transmission control module. Additionally, issues with the wiring or connectors related to the VSS, or a failing instrument cluster, could also contribute to these problems. Lastly, low transmission fluid levels or a failing transmission could further complicate shifting performance.
My grand does the same. It may be related to sluggish transmission. Pressing gas pedal gradually reduces the problem
Had the same problem off and on in my 1999 Taurus. The speedometer needs to be replaced. The problem is in the speedometer and not the transmission like I was initially led to believe. My mechanic said it wasn't that big of a repair.Coincidentally, the vehicle speed sensor feeds information to both the speedometer and the transmission....See "Related Questions" below for more
According to page #104, fuse #24 covers the: Integrated control panel, speedometer, electronic automatic temperature control module.See "Related Questions" below for more
The speedometer is controlled by the speed sensor and it also sends signals to the transmission on when to shift so your problems could be related. The speed sensor is easy to replace and is located on the transmission.
Any transmission related failure. You need to have the transmission computer checked for codes to know possible causes.
according to the owners manual this could be related to a problem with the ABS. I have the same problem and am looking for a diy solution. also from the owners manual the ABS controls the transmission , and my transmission is shifting roughly, which is what I noticed before I noticed that the speedometer wasn't working.
The vehicle speed sensor is the #1 suspect - it feeds critical data to both the speedometer and the transmission. See "Related Questions" below for more, including picture links, about the VSS
Code P0700 on a 2006 Dodge Grand Caravan 3.3L V6 indicates a general transmission control system malfunction. This code is often triggered by issues within the transmission control module (TCM) or related sensors. It typically requires further diagnosis to identify the specific cause, which could include problems with transmission fluid levels, wiring, or other transmission components. It's advisable to have a professional mechanic perform a thorough inspection to determine the root cause and necessary repairs.
The traction control light primarily indicates issues related to the vehicle's traction control system, which helps prevent wheel spin during acceleration. While it is not directly linked to transmission problems, malfunctions in the vehicle's speed sensors or stability control systems—which can affect traction control—may also impact transmission performance. Therefore, while both systems can be related, a traction control light does not necessarily mean there are transmission issues. It's best to have the vehicle diagnosed by a professional if the light comes on.
Error code p0605 is related to the Transmission control module.
