Trasmission oil change

metal ones about 100000 miles rubber ones about 60000 miles

This light comes on every few thousand miles, just a reminder to change oil. To reset it I believe on yours turn the key on press the excellerator pedal 3 times within 5 seconds, turn the key off. This should clear the light.

oil change every 3-4k miles

service every 10k miles

6000 miles ,cheapest oil and a oil filter every third oil change

New cars and truck manufactures recomend differend types of grades of oil when the engine is new. What they don't tell you when the engine receives 30,000 miles on it the grade of oil can be changed for better lubrication. Use 10w30 for normal use upon changing oil.

make sure are using a genuine dodge oil filter and correct grade of oil to check further you need to have the oil pressure checked using a master gauge a garage would do this for you if ok replace pressure switch if very low could be pump and bearing wear is the idle speed set too low i would check this

Check the Oil Pressure Sensor. It is located to the left of the Oil Filter. Check the connection, then remove, clean the sensor, reinstall and check operation again. If this does not work, remove again and replace this Sensor. Based on miles (130K) it is about time for a new one.
I'm not a big believer in synthetic oil, but that is my own opinion. I used exactly what is recommended.
If this does not fix the problem, then you should check for a leak. When checking the Oil Pressure Sensor: also check to see if the Oil Filter is tight enough. Was a light coat of fresh oil applied to the rubber o-ring gasket before putting on?
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me on FixYa.com!

Then you might want to idle the low idle speed up a half a turm to see if that sovles the problem.

Draining the transmission fluid and replacing it with fresh and new fluid is where to start ..

I had same problem....valve seals were bad....dealer fixed free...warranteed 7 years or 70,000 miles...good luck!
