1 Year Later And I Could Not Be Happier.

I had Denny's Transmission rebuild my transmission just over a year ago. I checked around and they offered a good price and a Guarantee. They got my transmission rebuilt and in and out of the shop in just two days, The world is full of transmission rebuild shops. Here is one that has been going strong for 50 years. Fast and friendly service. I simply can not say enough positive things. I highly recommend


Love these guys

I took my Isuzu to them after Ammco wouldn't service my transmission because of b/s reasons and they did an awesome job. I have taken to them again to fix a leak in the transmission and they fixed if for and the cost to do the job was a fair price not to mention they have to be the most honest transmission place I have ever gone to and eveyone there is so pleasant to work with. I don't know the young ladies name in there, but she is awesome thanks for the doughnut :) I highly recommend these guys and will not take my truck or any of other vehical I own to anyone else. Hi Five to these guys!!!!


Denny's is the BEST!

I took my Jeep into the Cave Creek office of Denny's and met Randy who checked my transmission out. I had been told at another shop that my transmission was gone and I needed a new one as I had a 740 Trouble Code (and the yellow light was on). But Randy told me it was a sensor and to replace it. He gave me a LOT of other information about my transmission that no one else had told me. I believe Randy has forgotten more about transmissions then all the other mechanics have ever known. If you want an honest diagnosis and really reasonable prices then I haven't found a better place to go than Denny's. Fast, courteous, friendly, reasonable and great all around. Thanks Randy.



Excellent upgrade by garret

Denny's up graded my tranny for a fraction of the cost of any other tranny place. quality on time work at a major discount. Denny's will be the only tranny shop I ever use. Thanks


excellent experience

I cannot say enough about the great service I recieved. My truck was fixed the way I was told it would be and in the time frame I was told. All this at a fair price. These guys really know how to take care of people. Honest service at a fair price what else can you ask for.


awesome job

i went to denny's north had a wonderful experience,the manager wasreally honest with me and his staff was very helpful.i recieved my durango back fast and running perfect,i would not go anywhere else for transmission repair except them.


Total Rip Off

Quoted me an outrageous price to rebuild a tranny that he didn't even have to remove and install. Shopped around, and got multiple quotes for half the price with free pick up and delivery. Told him not to do any work and he charged me $100 bucks just to get my tranny back. Avoid this place at all costs!!!!!!
