T310 knocking!

Recommended Posts

T310 transmission started making a knocking sound. At 20 mph at a coast you can hear it pretty good. You can pull it into neutral and it stops. Hoping someone knows. Thanks

have you checked the drain plug magnets?  is it only in one gear? are you sure its a trans issue and not a rear end? (the sound will transmit up the drive shaft )

Sound like say there was a bolt and something was hitting the head of it every time it makes around.

Is this a new transmission or does it have a many miles?  Sometimes a gear will have a bad spot and sound like a knocking during coast.  If you have a T310 and its in low speed, the gear set directly behind the mainbox (in the rear box) is most likely the culprit of the knocking noise.

That being said this noise may go away after the bad spot gets worn down, but that's only if this is a new or Reman new transmission.

That's guys for all the input. Find the problem it ended up being the peanuts in the front drive. Placed them with new bearings and the sound went away. 👍🏻 Seems like I get one thing fixed and it's something else. Smh truck just started pushing coolant.
