Sudden and complete loss of the transmission while on the interstate going 65 MPH. No warning. Fortunately was able to coast to a stop on an exit ramp. Could have caused a serious accident. Vehicle had 40,751 miles. Repair covered under warranty. There should have been a recall for this. Others have had the same issue.
2017 Ram Promaster transmission complaints
Page 2 of 2: complaints 11 to 14 of 14, newest first, as owners wrote them.
When shifting from park to drive, after starting vehicle that has been off for hours, the truck will abruptly lurch forward and be resistant to braking. Only way to settle it down is shifting into neutral. This has happened about 5 times since I've owned it. Bought it at 13,000 mi. It's now at 25,000 mi.
When the vehicle is being driven on a road at posted speed limits and the vehicle is traveling downhill the automatic transmission will often downshift two gears causing the engine to over rev uncontrollably often to 4000 revolutions per minute. Furthermore, the automatic transmission will not shift to a higher gear during this time unless the driver accelerates hard while already being in a situation of over revving the engine. The automatic transmission will not respond to manually selected gear shifts during these "over revving" events. The automatic transmission will eventually up shift after several seconds of excessive revving and engine speed will become normal again once the vehicle is traveling on a flatter roadway. These "over revving" events can happen several times travelling down a long incline and only happen while going downhill. These "over revving" events, where the automatic transmission unnecessarily downshift several gears while traveling at posted speed limits are extremely dangerous. The vehicle at times has become unstable due to engine braking, on roads with wintry and wet road conditions. Several drivers of these vehicles have experienced similar events.
At 64000 miles my transmission went out on my 1500 promaster van I had minimal weight in it .
