2013 660 Volvo I shift losing pedal power


New Member
Need help. I have a 2013 Volvo 660 I shift that loses power from the pedal . Can pull over and sit awhile all and then go again for about another 50 plus miles or a couple of days and it will do it again. Volvo said it was the transmission and we had it worked on but the issue continued. We were told it could be the harness. We can’t afford for mechanics to say it’s this and that and let them fix it and not be the problem. Need to know if someone had the same issue and were able to fix the problem.
Frustrated and need help.
