Everything went well, but some of the hoses that were reconnected to the bottom of the radiator leaked transmission fluid. It was caught before anything major happened.

This time around oil change & fuel filter change was more expensive than last,

It turned out that there was nothing wrong with my car. Preston and the tech explained thoroughly to me what had made the a/c not work, and why repairs were not needed (I'm new to AZ). Honest and reliable. I will always come here and will recommend them to everyone.

Although I only needed a new battery, the electrical system was thoroughly checked so I won't lose another battery. The shop owner was extremely accommodating.

Hard to get anyone on the phone so you just have to keep calling until someone answers. Other than that they are very friendly and helpful. I will definately return for future repairs!

They were great about taking care of my repairs. Did have one minor issue, which was quickly resolved.

by - Verified Customer September 30, 2015

Told them I needed my truck fixed by a certain time, did not look for part until that day and could not locate it. They told me to go ahead and go on my trip and that everything would be fine. The part failed and my truck caught on fire. I was stuck in Indio California for 3 days. I feel this would have been prevented if they would have been a little more astute in looking for the part

Very friendly and honest. They also answer any questions you have about your vehicle.

by - Verified Customer July 08, 2015

Service took over 2 months, there were several misdiagnoses at substantial cost; the final, reparative diagnosis was the least expensive, and, it would seem, might have been the best place to start, given the information supplied by us at the outset.

Questions Answered by Callahan Automotive | Auto & Diesel Specialists
While driving i noticed smoke coming from ...
I would first check your battery connections, it sounds like possibly a ground is loose, or dead battery. If there is no audible click sound when you turn the key I would also see if it will start with the emergency brake on and transmission in neutral.
trying to find a used tranny
There are 3 choices on transmission possibilities on your vehicle. Ford used the 4r55E and 4R70W for their automatic choices that year and also offered a manual transmission the M5od-R1. To be for sure I would need the VIN number to help you. Also just a recommendation, Its always better to rebuild the transmission unless it is damaged beyond repair. For example, Yes the transmission might be cheaper but you have no history on that transmission and there is a very big chance on contamination in the unit. What kind of issues are you having?
a/c compressor went out and tension pully ...
Depending at what location it went through the timing cover, it could of rubbed where the oil pump is. Callahan Automotive and other repair pal shop would be more than happy to look it over for you and verify the issue.
First the left side at 27,000 and now the ...
no that does not sound right at all. Do you have any codes on the computer? It could be bad o2 sensors, tune up issue, fuel issue multiple things it could be. Make sure find a shop like our with the proper software to diagnose you issue a lot better.
It sounds like a module, relay or switch issue. Some electrical testing and diag will narrow it down. You need to see if there is proper power and signal going to the multifunction switch. There are some shop like ours that do a lot of electrical issues. hope that helps
Multiple issues can cause that same issue to happen. First off do you have a check engine light on? Does it run smooth or rough? Did it just start happening? I would really recommend having a shop look at the issue to see what it could be. Just to show how many things can cause this I will list a few : vacuum leak, fuel pressure, mass air flow sensor, tune up issue, timing issue, cat issue. Feel free to find the best choice of shop for you and bring it in. I hope this helped
