This is a weird one.I just had the transmissione rebuilt after the planetarys blew. the tranny is running great...except, at very light throttle when I pull away from a light, the tranny shifts and makes a very loud klunk/boom noise. It doesn't do it at any other time, only at very light throttle. Any other throttle positione and it shifts smooth as silk. Could it be something besides the tranny, maybe my Torque arm banging against it's stops?

 

I had that problem while back and it was my trans mount, when I 1st heard it I though I blew the tranny but it was just a trans mount.

 

Thanks, the tranny gets it's 500 mille check up next week so they can change it out.
