Hi. I have an 02 Dodge Diesel. When I start it it's fine but when I start to go I can only go about 20mph until it's warmed up a bit......maybe a mile or so then it's fine.
I've tried shifting gears and sometimes that works to throw it into low and work my way up. (it's an automatic).
Any suggestions if it's a sensor, tranny, etc would be deeply appreciated.....thanks!
