Just the solenoid??? Or also the sensor?

It would also be helpful if you filled your signature as to model year etc of your truck.

Another possibility would be that the fluid is too cold- simple check- restart the truck when the engine and trans are at operating temp, idle in N for a minute and test again.

 

Hi 02 dodge ram 2500 5.9 diesel yesi only replase the governor pressure selenoide also the new one look little different than the use one little smaller

 

As you may have seen in this thread- always replace sensor plus solenoid.

I would also like to ask you to do me a favor: Since English is not my mother tongue I really need you to take care to write in an understandable fashion, like spelling words correctly so I can look them up.

 

Hi i just replaced sensor and selenoide and it worked for about 30 miles (all good) but It starts to do it again....😞 stays in second gear never go down to first gear everything else is good

 

I was having a shifting problem on my truck and found out it was a broken wire between the computer and the trans. Just something else to check. Hope you solve the problem asap.

 

Ok thats my next step to check thank you so much but why would you think that worked for 30 miles and start doing it again??
