Hello,

I recently bought a truck with a 9 speed transmission. I am new to this type of trannys and am learning how to drive it smoothly.

But, I am having a big problem with initial startups. I usually get the engine started and wait until the air pressure is up to normal operation conditions.

Then, I press the clutch all the way down to engage the clutch brake and try to put it into gear. Whenever I do that, the tranny starts grinding and the grinding comes to a stop. Then, I could put the transmission into gear.

I think there might be something wrong with my transmission. Is this normal or is some part worn out (clutch brake perhaps)?

I would really appreciate any opinions. Thanks
