Transmission coolers service near Chicago, IL

Dan is the man. He is one of the guys you see first and he is always smiling. He is very nice as well as very knowledgeable in the automotive industry. He won't try to sell you something you don't need. Very fast oil change and I got a text from them when it was all ready. Go here for a hassle free job. Highly recommend this place.

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

I took my ML 350 due to a problem with the Engine. The drive chain had broken. The dealer's recommendation was to repair and cost was something of buying another car! So, I took to Dupage Auto Werks. The recommendation is to replace the 118K miles engine with a much lower engine. They shopped and found a fimilar engine and practically did a 'Engine Transplantation'! Now that I have an engine not only has a lower mileage, but also was cheaper overall. Very satisfied with them to have suggested and able to get my car worth somehting that I can keep it a much longer time!

I found that Bob is one of the most honest mechanics that has worked on my car. That is one reason, I will return to him to work on my car. The other, which is also important, I am very satisfied with the work he has done. I will be returning to him when I need additional repairs.
