1998 dodge dakota 5.2 litre 2wd, automatic trans. (44RE) recently purchased. Truck will not shift. It seems to start out in 2nd gear. If I put the selector in 1st gear, it will start off in 1st gear and wont shift untill I move the selector to "D" then it will shift once. The tranny does NOT slip. Check engine light was on. Scanned and retrived po743, po753, po748 & po751. Cleared codes and drove truck over 20 miles under same conditions. Po743 is the only returning code now.
Trans fluid looks brand new. I checked fuse #16 trans. Control and it has only.4 volts going to it.
Any suggestions on repairs needed to correct?
Regards
BK

The codes are shift solenoids and the torque convertor clutch solenoid.

Have it diagnosed by a reputable trans shop, on most trannys you can replace shift solenoids and TCC solenoid without removing trans.

P0743 TCC solenoid

P0753 Shift solenoid "A"

P0748 Pressure control solenoid "A"

P0751 Shift solenoid stuck "off".

Ty, but I know what the codes relate to.
The sensors and solenoids are inside of the 44RE trans. After clearing data and reseting the OBD the only returning code is the PO753 shift solenoid A.
The reason I asked the question was to hopefully avoid takeing it to a trans. Shop.

Found the problem. It was electrical in the junction box under the hood.
Cost to repair ZERO dollars, except for the 10 dollars I wasted on this site.
I am disappointed in the generic answer you posted, it's that kind of advice that gives the good honest technicians a bad rap.
If you don't know. Simply say I DON'T KNOW. Or better yet, let someone qualified reply to the question.

Cheers.
