The transmission shifts erratically, slips or does not shift at all. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.My info is somewhat limited on your model here but I had seen no one else has responded and would like to see if I can help here.If at any time you feel that I cannot help with this please let me know.This may be an issue with the transmission valve body itself as this is a known issue in some cases for a fault like this here.If you can clear out the codes then operate the vehicle as best or much as possible until the fault occurs and see which code sets first here and let me know this will help.The code P0670 looks to be a fault with the glow plug circuit,glow plug or glow plug controller/ecu itself.This wont cause a shifting issue here but can cause start up faults and needs diagnosed to locate and repair the issue here.The code P1839 is a fault with the transmission fluid temp sensor.This can be a faulty temp sensor or wiring inside the transmission to the sensor needing repaired and can cause shifting or other transmission issues.This will have to be checked into/tested further as well to pinpoint the cause and then repaired from there.I suspect the temp sensor is at fault needing replaced as this is most common.If more help is needed, use the reply tab to continue our conversation. It's also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts. After it was replaced, we are still having the slippage in shifting.
