I am extremely impressed with the service I received. I believe I have found a good honest automotive repair shop to keep my vehicles running. The owner takes pride in his work and it shows in both his customer relations & work. I will now test him out on an even bigger job.

I called on a Saturday morning for an oil change and they got me in the same day and checked other things on the car to be safe. Great Job Preston.

Trustworthy and talented crew.

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!

Knowledgeable staff, a bit pricey, and unfortunately busy when I brought my truck in.

Got major repairs financed and my car is still having the same issues. Will be calling the better business bureau because of how frustrated I am. Car is worse off before it went in and it took them 3 WEEKS to receive my car back, barely able to run.

Very professional, they explained everything to me before they started the work so I knew what I was paying for. And I was happy with the price.

Preston and the guys were great and explained everything didn't take advantage of a woman like most auto shops do.

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

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.

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.

by - Verified Customer May 29, 2015

Friendly service, helped us out right away, knowing we were from far away and made sure we were a priority.

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
