2026 Ram 1500 transmission problems

2026 Ram 1500 Rebel equipped with 3.0L Hurricane I-6. When Auto Start/Stop shuts the engine off at a stoplight, the engine restarts but on two occasions the vehicle has not responded to accelerator input. I have rotated the gear selector from drive to park and back to drive and the vehicle responded to throttle input. The condition has not occurred when Auto Start/Stop is manually disabled. Dealer inspected vehicle after first occasion but could not duplicate the condition and found no diagnostic trouble codes. Loss of acceleration after restart presents a safety concern when pulling into or crossing traffic.

Vehicle returned from warranty repair at MainStreet CDJR of Lansing with severe mechanical negligence and federal compliance breaches. The dealership left critical drivetrain components completely loose, including rear transmission mount bolts and cooler lines, creating an immediate highway safety hazard. A separate, certified Ram dealership has since inspected the truck and generated a formal work order explicitly documenting: "Loose bolts left from prior dealer." Furthermore, the initial dealership assigned an uncertified student trainee (Tech ID 1078) to perform this advanced powertrain warranty work and subsequently signed off on a critical federal occupant safety restraint recall completion. The General Manager verbally admitted to the consumer that the servicing technician was uncertified and currently still attending training classes. The dealership held the repair ticket open locally for 33 days to actively manipulate data and hide the compliance paperwork from corporate

While driving at highway speeds, a severe transmission defect caused an electronic and mechanical failure chain on my 745-mile vehicle. The transmission experienced an immediate loss of hydraulic control, causing the engine to surge to 4,000 RPM and violently slam three separate times under load, attempting to force a gear engagement (DTC P076F-00). This severe physical trauma caused the Transmission Control Module (TCM) to completely drop communication with the Engine Control Unit (ECU), throwing error codes U0080-00 (Ethernet Bus 1) and C2226-00 (TCM Disabled ECU).The vehicle's safety software responded to this network crash by entirely cutting transmission line pressure. This architecture resulted in an instantaneous and catastrophic Loss of Motive Power (LMP). The vehicle entered a dead-freewheel state, causing it to roll backward on an active, inclined freeway off-ramp into oncoming traffic. A severe collision was avoided solely due to immediate driver reaction time. The driver and a [XXX] passenger were left stranded in a live traffic zone. Dealership Repair Order #XXX explicitly documents this loss of motive power and unintended directional movement. However, the manufacturer's current remediation plan completely ignores the severe electrical and structural trauma. The dealership is attempting a superficial valve body replacement based on a stationary shop air test. This low-pressure test cannot inspect for warped clutch steel plates, glazed friction linings, micro-fractured planetary gear teeth, or torque converter clutch fatigue caused by consecutive 4,000 RPM shock-loads. Furthermore, a mechanical valve body fails to address the high-speed Ethernet bus crash that disabled the TCM. This vehicle suffers from an unpredictable, systemic electronic and mechanical safety defect that creates an immediate hazard to public safety.

At a red light, the truck flashed all lights then refused to move. I tried to put the truck in park and turn it off and back on again but it didn't ever turn on again. The truck was towed to the dealer 13 days ago now. They fixed all safety recalls but it didn't resolve the issue and the truck still will not drive. The manufacturer is refusing to repair what the dealer believes to be the issue.
