I have a 1996 Ram 5.9 auto 2wd. It's in not changeing gears. Its takes off in 3rd gear. I can shift it manually and it will change but thats the only way. Is also dont change into OD. I was told it was the transmission solenoid, but I'd like to make sure before I send over $100 for one. I'm not getting any codes or anything.

 

Does your check engine light work? Maybe the bulb is burnt? Will it manually shift into OD? What does the fluid look and smell like? There are 3 solenoids and one sensor in the transmission.

 

the light does work. fluid is fine it shifts from 1st to 3rd manually only. not OD. the trans was perfect put the truck was parked for a little over a year. Now the trans is doing this. The trans was replace by the dealer a few years ago but now has around 80k on it.

 

Check out your wiring harness going to the transmission. Make sure some critter didnt get under there and go nuts with the wiring.

It sounds like the transmission is in limp mode, but usually you cant manually shift while its in limp mode, i dont think.

 

well a dog did chew the jumper wire that plugs in the side and I got a new one from the dealer but I'll check for more damage.

 

Well, I got back under the truck today looking for more damage. I didnt find any, however I did fine a wire unpluged next to the other one that I had replaced. I pluged it up and now all is well. Thanks very much. You saved me alot of money.

 

Youre welcome. Im glad it was something simple.
