P0843 allison transmission code.
These codes indicate that you're having pressure dropping out. The P0841 and P0843 are C shift valve dropouts and P0846 is D valve dropout. Because it is setting when temps are colder, make sure that you have good fluid level. Check it in Park with the engine running and trans warmed up.
Also, DTC P088A becomes active concurrently with these other visible filter maintenance alerts. This DTC monitors the electrical state of the PS2 FLI pressure switch. If PS2 is detected as open (pressurized) while the transmission is in a forward range and with the Torque Converter Clutch (TCC) (lockup) solenoid energized, the DTC becomes active.On 7-speed automatic transmissions, 1st and 7th gears are not activated, torque converter lockout.

DTC P0843 code stands for Transmission Fluid Sensor/Switch “A” Circuit High. It’s logged when the PCM or TCM receives a voltage signal from the TFPS that doesn’t match the normal operating voltage. Some issues that could trigger the P0843 code include a bad TFPS, a malfunctioning PCM (or TCM), and circuit-related issues.Allison 1000 & 2000 Gen 4 Fault Codes: P0880 TCM Supply Voltage. DTC P0880 sets if an abnormal power-down sequence has occurred. This condition means the Transmission Control Module (TCM) has lost supply voltage (wire 103) before it has finished saving information from that drive cycle. This process is usually completed in less than 10 seconds. 1.Mar 12, 2014. #1. Received these two codes the last two mornings. P0848 - Transmission Fluid Pressure Sensor/Switch "B" Circuit High.

At ~100 feet it went into neutral with these two codes present.The transmission system contains numerous components that can fail over time. Here are related TFPS “A” circuit codes. P0840 Code: Transmission Fluid Pressure Sensor/Switch “A” Circuit; P0842 Code: Transmission Fluid Pressure Sensor/Switch “A” Circuit Low; P0843 Code: Transmission Fluid Pressure Sensor/Switch “A” Circuit HighWhat the P0843 code means. P0843 is an OBD-II generic code for a voltage problem with the transmission fluid pressure sensor in that the signal being sent to the engine control unit is higher than the manufacturer's parameters for the desired amount of fluid pressure for that given driving condition. This means that the fluid pressure needed ...
The P0880 code in Allison transmissions indicates a problem with the transmission control module power input signal. This code typically occurs when there is a fault in the TCM power supply circuit. When the P0880 code is triggered, it is important to inspect the TCM power source and related wiring for any signs of damage or loose connections.
