I just finished installing my dual disk yesterday and going down the road its making the same noise that it does in neutral is this normal? Its the 3250 dual disk if that helps

 

Like what kind of noise, humming, rattelings, ting, ping, pang??? I can think of a thousand noises that have come from transmissions. Who put it in????

 

I would say its more of a rattle, it almost sounds the same as when its in neutral but it does it going down the road. My diesel mechanic and I put it in. but when you first take off it goes away and then comes back in every gear.

 

Did you replace the pilot bearing? and check the input shaft's pilot surface to make sure it was not worn?

 

Ya we replaced the the bearing. I called southbend today and he said it was normal when you lug it but I didn't think anything over like 1400 was lugging it with 4.10 gearing

 

Its also just gettin warn in..
