1996 Sebring Convertible P1782 Code: Transmission Shift Issues and Thumping Noise Explained

Model: 1996 Sebring Fault Code: P1782 Posted: 2009-07-10 10:31

I own a 1996 Chrysler Sebring Convertible with a 2.4L 4-cylinder engine. Recently, the car has started having difficulty shifting into higher gears—sometimes it won't shift at all until I turn the key off and back on. Additionally, I'm now hearing a thumping sound when coasting. My OBD2 scanner shows fault code P1782, which indicates a 'Manufacturer Controlled Transmission' issue related to pressure switch circuit (2-4). What could be causing this? Is it likely a solenoid pack failure or wiring problem? I'm considering replacing the transmission control module but am concerned about cost—replacing it at $169 would be expensive if it's not actually the root cause. Any insights into possible causes or diagnostic steps would be greatly appreciated.

P1782 in a 1996 Sebring typically points to a Chrysler pressure switch circuit issue (range 2-4). The most common causes include a faulty solenoid pack or related wiring. This code is often linked to transmission control and pressure monitoring systems.

Thanks for the clarification! I now have a clearer direction to investigate before replacing the transmission control module. At $169, it's not something I'd want to replace without confirming the actual root cause. This advice helps me avoid unnecessary expenses and focus on more likely issues like wiring or valve body problems.

I strongly recommend getting a professional diagnostic check for this code. Before replacing any components, it's important to rule out simple issues such as faulty wiring or a malfunctioning valve body—these are more common than solenoid pack failures in older Sebring models with P1782.
