Check transmission system at next stop light on. HELP!!!!

Did they tell you what was the warranty time or mileage on the trans. My truck just had the same problem... Drove it for about an hour and went away...I Bought the truck used (2015 Volvo)and had around 480k miles now It has around 542k miles. Please reply or call me. Mike 815-483-5685

 

Hi your truck had 55k or 55miles cause

i get the check the gear selector at the next stop message is this same for transmission cause I can’t go transmission faults it says operation failed

 

What’s the part number are you referring to the ribbon harness on top of the trans

 

I have 2014 Volvo vnl 630, I shift with D13 motor. Lately it has started
losing power momentarily on uphills, with "check transmission on next stop" sign. It jerks a few times but then starts driving normal with no warning sign or message.
A couple months back it was losing coolant significantly without a trace but after I added Blue Devil liquid, it stopped. Now I have started losing coolant again without apparent leakage.
Wondering if both issues are related, something wrong with turbo, clutch (it's a year old), air supply to transmission or transmission itself??? Please help.

 

I had the same issue with my 2016 volvo with D13 motor , its now third time i got a warning sign that check transmission at next stop , that warning sign disappears within 5-10 seconds. Truck is running normal not slipping any gear, M gonna drop it to mechanic this friday lets see what happens. Your suggestions are appreciated.
