2003 Chrysler Town and Country P0601 Code: Is It Causing Transmission Limp Mode or Gear Slippage?
My 2003 Chrysler Town and Country is displaying OBD-II fault code P0601, which indicates a problem with the Powertrain Control Module (PCM). I'm concerned that this issue might be causing transmission problems—specifically, gear slippage when accelerating and sudden, harsh downshifts just before coming to a stop (around 3 mph). The vehicle runs smoothly in neutral but behaves erratically in drive or reverse. Is limp mode triggered by P0601? Can a faulty PCM cause these transmission symptoms? I've checked the code with an OBD-II scanner, and it reads P0601 consistently. Any insights on whether this code directly affects transmission performance or if further diagnostics are needed? Thank you for your help.
Does your OBD-II code reader scan both generic and specific fault codes? For more details, refer to this resource: https://www.obd-codes.com/p0601. P0601 typically points to a PCM memory or data corruption issue, but it's important to confirm whether the transmission behavior is directly linked to the PCM or if other components like the transmission control module (TCM) are involved.
