    We have a Volvo I shift with a 455 engine and she keeps losing power. Shut her off and sometimes it kicks back in again. Changed speed sensor. 4 wire harnesses pipe for def and wires to batteries. Get up to 5 gear in Manuel and kicks out speed and power again. Anyone have any ideas. She's a 2015

    Yes. A few different ones. First one came up was one for speed sensor so we changed that. Was good for a couple days next one was one similar and they changes 4 harnesses. This one is mid 144 psid 230 fmi 5 which they fixed some going to the battery. But still same problem.

    It went out eventually and I had to get a row. It started out losing power and having to let off the gas then press again to get it to change gears. I felt fully loaded going up hills barely creeping.
