I have a 1998 dodge ram 1500. My transmission wont change to 4th gear. I changed the governor solenoid and pressure sensor and speed sensor and nothing happened. I also noticed that when I press the od button it doesnt turn on but so do other stuff like when im not wearing seat belt the lwarning light doesnt turn on eitjer. Only check engline light and gas light turn on. Transmission came from a 2500. Thank you

Get the code for us.

Sounds like an internal failure in the clutch or valve body

Go to a parts store and have them pull it for you. Do not let them sell you any parts. They are salesman, not technicians

Theres no code for it. The check engine light is on because of the oxygen sensor but that was it

I know. It is an internal issue either with clutches or valve body.

Do you think it has anything to do with the fact that my OD button doesnt turn on?

Yes, that is part of it and will be determined when the failure is identified.

Havin the same problem with my truck but does have codes P139: Loss of Cam or crank and P0783: 3-4 Shift solenoid malf. A couple weeks ago it would stall shifting from 2nd to 3rd, go to higher rpms before hitting 3rd then would dump into 4th. Now the the day after I pull codes it now shifts fine 1, 2, 3 then no 4. Bout 2800-3000 rpms at 60

That sends a signal to the module and the module activates the torque converter solenoid to allow fluid to apply the clutch in the converter.
