I have a 2001 ram 3500 cummins with the 47re recently it started out with overdrive light would flash and trans temp light came on and it kick in then out of overdrive
I changed the pressure transducer senor and that fixed that problem.
Then truck wouldn't shift out of 1st changed the speed senor it fixed that problem (for awhile)
Now it doesn't want to go into first at all it starts out in 2nd then every now and then it wants to stay in first then it shifts out and shifts through all other gears as it should stop at a light then it wants to start out in 2nd. Then shut the truck off start it back up and sometimes it will work perfect then when I stop it Dont want to go into first
