I researched my archive of Snap-On data movies for this transmission and found that the readings indicated were incorrect. In this example, the scanner data graph for the vehicle speed sensor is running slower than the wheel speed sensors. Now that we know the definition of the P0215C code, and what will set it, I asked the shop tech to provide some scan tool information. Interference or damaged wiring in the CAN Bus systemįirst things first.Mechanical faults with transmission gearing.Broken, damaged or worn reluctor gear teeth.Excessive metallic debris on transmission speed sensor.Also, the malfunction indicator lamp will be illuminated. If either controller detects a discrepancy between the vehicle speed and the wheel speed that exceeds the maximum threshold, the code P0215C will be set and stored. It did not have these problems with the original transmission according to the dealership technician.

The used replacement transmission solved the unknown problems with the original transmission however, it now had a recurring coast downshift clunk and a P0215C with the replacement transmission. It arrived from a local dealer where they installed a used transmission. This vehicle was fitted with a 948TE 9-speed transaxle with a 3.2L engine and a 4WD drivetrain.

This vehicle came in with a P0215C code and a rough coast downshift. One example was a customer with a 2015 Jeep.
JEEP VIN DECODER FOR GEAR RATIO INSTALL
When you are replacing parts, or the entire transmission assembly, you need to know what ratios you are removing so you can install the correct one. Otherwise, you may create a problem that you did not have with the original transmission. The modern car is very integrated from one module to the next and from one gear ratio to another. What am I talking about, you ask? Gear ratios. Transmissions may look the same from the outside, however, it is what is on the inside that can make a difference between a successful repair or a costly one.
