HELP PLEASE
99 durango 5.9 4wd
when you take off the speedo wont start untill almost 30 mph,sticks in first or second I have to nail it then let off and it will shift, if shifting semi right between 1and2 it will only stay in 2nd of a split second then shift to third, oh ya if you hammer it-good luck it will redline and go nowhere just revs and no gear. i have obdII reader and changed output speed snesor on tran with no luck. throws no codes,about ready to trown my 20lb hammer at it. please help before my wife gets really stranded somewhere.
oh one more thing when the cc is set it will jump 2-300 rpm for no reason.

Hey Seth
I had the same problem with my 98' Durango. I had to get the whole tranny rebuilt. It gets worse if you go up hill with this problem. My transmission guy told me that the tranny is built with an extended shaft for over-drive and thats what srews up the tranny.
Good Luck

 

You will need your governator actuator switches replaced. I am suprised you did not get a check engine light come on to let you know? Your description is exactly what happened to me. I have to nail it to force it to upshift. My check engine light came on. Went back to dealer and got the governor actuator switches replaced under warranty.
