Transmission Dipstick Problem

[Eric Johnson]

Hi Kerry,

I agree with you on the weld as responsible for the first dipstick break. I am
really puzzled
by the latest break of the 3 year old dipstick supplied by Blue Bird. It didn't
have any
welding done on it. I have another dipstick on order but doesn't feel like I'm
fixing the
root cause.

Thanks, Eric
