Check engine light came on my XJ and it looks like it might be a P1898. After doing a quick check, this is what I found...
Anyone here ever deal with this?
Vehicle Application:
1997 Jeep Cherokee Sport 4.0L
Customer Concern:
Transmission code P1898. Transmission does not shift correctly or Torque Converter Clutch (TCC) is not working correctly.
Tests/Procedures:
1. Check if the TCC is working OK. The code is either for solenoid #1 functional fault or the TCC solenoid functional fault.
2. If solenoid #1 is stuck open, the transmission will only get 1st and 4th gear. If solenoid #1 is stuck closed, the transmission will only get 2nd and 3rd gear.
3. If the TCC solenoid is stuck closed, TCC never locks up. If the TCC solenoid is stuck open, TCC stays locked up all the time.
Potential Causes:
Solenoid #1
Torque Converter Clutch (TCC) Solenoid
