My name is ***** ***** I will assist you.

Your bus will not be the same as the Columbia. That bus model and year is the same as the M2. I am attaching the transmission interface diagram. See if this is what you needed.

You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see,
touch, smell, hear, or taste the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

The system DOES NOT automatically give me credit from your deposit. A rating is REQUIRED. You are rating me for the information I provide,
not the website. I have no control over the site fees, site errors, category errors, or how long it took for a response for these reasons.

I am not an employee of this website, so please rate with a POSITIVE (green) rating for me to get credit for assisting you. You still pay
the website for negatives or by not rating at all. I just get nothing from that payment you made. So please rate each answer I provide.

I want you pleased with my service to you so please inform me before rating negative (red) and I will do my best to make it right. Follow
ups for same question are always free after ratings have been made.

I do have many workshop manuals, diagrams, etc that I pay to get access to out of my pocket. If one is needed, please ask and I will give
you an offer at my technician discounted cost to you for such manuals. I never charge above that cost.

Thank you for allowing me to assist you through Just Answer!

There must be a glitch in the system for I never saw or responded to this question. My response I have on there is to another customer I've been working with all day... I will have to report this glitch.

I apologize that the system glitched on you. The person you want is Andy who is the International dealer expert. I will opt out of this since the system glitched and put my repsonse of another question on here.

He should be along shortly.
