Wont shift out of 2nd gear 1998 Dodge Ram 1500 5.2 l v8 SLT Laramie

1998 Dodge Ram 1500

My truck got into 2nd gear but after that it would not shift out of 2nd gear

Is this an automatic or stick shift?

Manual Transmission

The synchronizes are out or the clutch is not working. Possible worn clutch disc or faulty clutch master/slave cylinder.

Automatic Transmission

Most likely a shift solenoid in the main valve body of the transmission.

Have a transmission shop or dealership scan the TRANSMISSION CODES, not just Engine Codes.
