ok i have a 97 ram i put this tranny in 2 months ago and now it lost 3rd and overdrive other gears are fine now engine light come on code 45 so i changed the 3- 4 shift solenoid and the TCC solenoid and still the same so what iam i missing here anyone got any ideas

 

Are you sure 3rd is missing, and not just 4th, and TCC lockup?

What's the history on the trans? Was it used? Rebuilt?

 

yea iam sure i can shift it from 1st to 2nd and thats all its got the tranny i got used from someone that smashed his truck up and it was rebuilt 3 years i think he said when i took the pan off it was super clean and i took it to a shop to get it scanned and they couldnt come up with anything then on the way home code 45 poped up and i got the other parts out of a truck that i know worked but was rusted so i just dont understand what iam missing here

 

What year was the donor truck?

You should get third gear as well....... if you don't, there is more than a solenoid problem...... might need to take it somewhere to have it diagnosed......

 

If your not getting third gear, that means that the piston seals on the front clutch are leaking and not holding pressure, and you can't get OD without 3rd,because it's a split gear range.

You can pull the valvebody down and air test the trans thru the ports that the valvebody uses. You can actuate the servos and the front and rear clutch pistons to make sure everything works and is holding pressure.

I can give you a definition of ports to test if you would like.

 

That information would be great to have. I would certainly appreciate you posting it up.

 

my truck is a 97 and the tranny was out of a 98 i did change the valve body to and then i started taking the tape off the wiring to the tranny and found that 2 wires were burnt alittle and were stuck together and have no idea how that happen but i fellowed them to the neutral safety switch so i fixed that all up and didnt really think that would make the truck do this so i gave up till it was time to pick up my wife from work she just works down the road so i jump in the truck and it worked fine been driving it all day so it was them 2 wires for the neutral safety switch has anyone ever heard of that i have been working on cars and doing my own work all my life and did not think of that but anyways thanks for the help guys

 

Awesome. Glad it was an easy (and cheap....) fix.

 

yes its all ways is better when its cheap and easy but now i found the bearing is going in the rear end i just bought this truck 3 or 4 months ago time its done there will be nothing org on the truck and this comming up weekend i have to fix the rockers and bottom of the doors the truck is white and the small spots of rust popping up on it sticks right out and i hate that and its better to do now then when there isnt anything left on the truck to fix and thanks again for the help iam sure you will see me posting again looking for help lol
