The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
On rare occasions, a knock noise from the bellhousing area of the engine and transmission may be experienced on vehicles with low mileage.
If this concern is encountered, inspect all of the torque converter bolts to ensure that they are not cross threaded, and that they are torqued to specification. If a loose bolt is found, torque it to specification and re-evaluate the noise.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
