45RFE transmission won't upshift into 3rd or 4th
Hi guys, I have a 2001 Dakota sport, Not throwing any codes and fluid level full, when I drive it I noticed its shifts into second a tad harsh and aliitle above 2k rpm which it normally shifted into second before 2k. and of course won't upshift into 3rd or 4th. Could this be the shift soleniod ? or some short of sensor? any ideas what to check?
