Ram Power Train Recalls: Transmission Leaks, Rollaway and Power Loss
Ram power train notices repeatedly address loss of Park function, unintended movement, and loss of drive power. Ram 1500 models recur in the 2018-2019 axle and driveshaft notices, the 2018 park lock rod notice, and the 2019 four-wheel-drive transfer case notice. Heavy-duty transmission leak notices cover certain 2019-2020 Ram 2500 and 3500 pickups, then certain 2020-2023 Ram 2500 and 2020-2022 Ram 3500 vehicles. ProMaster notices describe shifter cable separation on certain 2014-2019 vehicles with 3.6L engines and incomplete park pawl engagement on certain 2019-2021 vehicles with 62TE transmissions. Other notices concern shift interlocks, transmission control units, and inaccurate gear displays.
Warning signs to watch for
- 2020 ProMaster shifter cable recall W00: intended shifts may not occur, and lever position may differ from the actual gear.
- 2019 Ram 1500 transfer case recall W06: the truck may become stuck in neutral, lose power suddenly, or lose Park function.
- 2025 gear display recall 36C: the gear selection display may be inaccurate.
- 2018 shift interlock recall: the transmission may shift out of Park without brake pedal application or a key in the ignition.
- 2018 rear axle oil level recall: axle failure may cause loss of drive or rear wheel lockup.
Can you keep driving? What the notices say
The supplied notices do not carry any stop-driving or park-outside instruction. The transmission fluid leak notices W03 and ZA3 do not tell owners to stop driving. The supplied shift interlock, park lock rod, rear axle, driveshaft, ProMaster shifter cable, paratransit shifter cable, transfer case, ProMaster park pawl, transmission control unit, and gear display notices also do not tell owners to stop driving. These statements report the notices' instructions and do not establish the operating condition of an individual Ram.
What the free repair involves
Free remedies include ZA3 dipstick and vent replacement, U43 park lock rod installation, V48 driveshaft replacement, W00 shift cable replacement, W06 transfer case replacement, 63B valve body and control unit replacement, and 36C cluster software updating. W03 specifies separator plate replacement and PCM reprogramming; its supplied notice does not state that repair is free.

Common questions
Do the two transmission dipstick leak notices specify the same repair?
W03 specifies replacing the transmission valve body separator plate and reprogramming the powertrain control module. ZA3 specifies replacing the transmission dipstick and vent assembly free of charge. The supplied W03 text does not state that its repair is free.
Why can a recalled ProMaster's shifter position differ from its actual gear?
The January 2020 W00 notice describes a shifter cable that may separate from the transmission on certain 2014-2019 ProMaster vehicles with 3.6L engines. Intended shifts may not occur. Its specified remedy is free transmission shift cable replacement.
What repair addresses the Ram heavy-duty gear display problem?
Recall 36C describes a software error that may make the gear selection display inaccurate on certain Ram 2500 and 3500 vehicles with a 3.5-inch cluster and column shifter. Dealers update the cluster software free of charge.
