'66 D200 np435 noise

Post by Txas2step »

I have a very slight rumbling sound in the np435 while idling in neutral.As soon as I disengage the clutch, the sound goes away. The trans. shifts well and does not make any noise in any gear. Throw out bearing is set properly and is not spinning until engaged. Any thoughts? :thinking ( trans alignment?, input bearing? motor mounts?) :study
