Ram 2500 intermittent transmission limp mode issue with shifting from 1st to 4th gear on Ram 2500

Some Ram 2500 owners report experiencing intermittent transmission limp mode issues, where the vehicle shifts from 1st to 4th gear only. This limp mode typically engages when the transmission detects a problem, restricting gear changes to ensure safe operation. Owners have noted that this issue can arise during various driving conditions, including towing, normal driving, or even after an engine swap. Additionally, some drivers report high transmission fluid temperatures without any accompanying error codes when the vehicle enters limp mode. While resetting the limp mode can be a straightforward process that owners can perform themselves to avoid costly repairs, it is advisable to check for error codes to identify the specific issue. If the problem continues or further assistance is required, consulting with a mechanic or dealership equipped with specialized diagnostic tools may be necessary to address the underlying cause of the limp mode.
