#F4a42 transmission problems code

In some cases, it may be necessary to reflash the PCM or transmission module to cure a particular fault. You should also check for any technical service bulletins (TSBs) that may be related to the transmission problem. This kind of information can be found in OEM service manuals, on OEM websites (daily one-time access fees are typically $15 to $25), or through online technical information service providers. YouРІР‚в„ўll also need the applicable service information that includes wiring schematics and OEM diagnostic charts with test specifications for all the components that need to be checked. This will require a digital multimeter (DMM) that can read voltage, resistance and Р’Вfrequency or dwell. If you find a transmission fault code, you may have to check the resistance of a solenoid in the valve body, its operating voltage or theР’В Р’Вfrequency of its control signal from the Р’Вcomputer. So, these sensors should also be checked. Some engine sensor failures can also affect the operation of the transmission.

Some electronic transmission problems may or may not set a fault code and turn on the MIL lamp, so itРІР‚в„ўs important to always scan the PCM or transmission module for codes if thereРІР‚в„ўs a transmission-related complaint or driveability issue. Problems here will typically cause the transmission to go into a РІР‚Сљlimp inРІР‚Сњ mode that may lock it in 2nd gear. Either way, youРІР‚в„ўll need a scan tool to access fault codes and operating data.Р”Р„ scan tool can also help you check for communication faults between the PCM and transmission controller if the vehicle has separate computers. But on some vehicles, the information is often found in a separate Transmission Control Module (TCM) or Body Control Module (BCM). Transmission codes and sensor data on late-model vehicles is accessed through the OBD II diagnostic connector and the Powertrain Control Module (PCM) diagnostic gateway module. But with todayРІР‚в„ўs electronic controls, you need a scan tool, scope, and a multimeter. You also needed a vacuum gauge to check the engineРІР‚в„ўs intake vacuum and the integrity of the vacuum modulator. Back when transmissions where purely mechanical and hydraulic, all you needed was a set of high-pressure gauges to check line pressures. When overhauling and diagnosing transmission units, you will often need special tools. These devices shift the gears, lock the clutches and regulate the fluid pressures.
