RAM Promaster is one of the most reliable cargo vans in the market. However, like any other vehicle, it can develop issues, such as failure to shift gears. This issue can be frustrating, especially if you are in the middle of a trip or carrying heavy loads. In this article, we will discuss the causes of RAM Promaster won’t shift issue and the possible solutions.
What Causes RAM Promaster Won’t Shift Issue?
There are several reasons why your RAM Promaster may fail to shift gears. One of the most common causes is a transmission fluid leak. If the transmission fluid level is low, the transmission may not be able to engage the gears properly.
Another cause of RAM Promaster won’t shift issue is a faulty transmission control module (TCM). The TCM is responsible for controlling the transmission’s electronic components. If it fails, the transmission may not shift gears or may shift gears erratically.
A worn-out clutch or pressure plate can also cause RAM Promaster won’t shift issue. The clutch is responsible for engaging and disengaging the gears. If it is worn-out, it may slip, making it difficult or impossible to shift gears.
Additionally, a damaged or worn-out shift cable or linkage can cause RAM Promaster won’t shift issue. The shift cable or linkage connects the gear shifter to the transmission. If it is damaged, the gear shifter may not be able to engage the gears properly.
How to Fix RAM Promaster Won’t Shift Issue?
The solution to RAM Promaster won’t shift issue depends on the underlying cause. Here are some possible solutions:
Check the Transmission Fluid Level
If the transmission fluid level is low, add more fluid to the recommended level. Check the owner’s manual for the correct type of transmission fluid to use.
Replace the Transmission Control Module (TCM)
If the TCM is faulty, it may need to be replaced. A qualified mechanic can diagnose the TCM and replace it if necessary.
Replace the Clutch or Pressure Plate
If the clutch or pressure plate is worn-out, it may need to be replaced. A qualified mechanic can diagnose the issue and replace the worn-out parts.
Replace the Shift Cable or Linkage
If the shift cable or linkage is damaged, it may need to be replaced. A qualified mechanic can diagnose the issue and replace the damaged parts.
Perform a Transmission Flush
If the transmission fluid is dirty or contaminated, a transmission flush may be necessary. A qualified mechanic can flush the transmission and replace the old fluid with new, clean fluid.
Conclusion
RAM Promaster won’t shift issue can be caused by several factors, including low transmission fluid, faulty TCM, worn-out clutch or pressure plate, and damaged shift cable or linkage. The solutions to this issue depend on the underlying cause and may include adding more transmission fluid, replacing the TCM, clutch or pressure plate, shift cable or linkage, or performing a transmission flush. If you experience RAM Promaster won’t shift issue, it is recommended to consult a qualified mechanic to diagnose and fix the issue.
