Transmission coolers service near Cicero, IL

What an amazing experience! I was greeted by the lovely owner, Debbie, and her little assistant. Debbie is so sweet, she made me very comfortable and I left the business knowing that I will return here with confidence. My service was fast and at a great price! My light is finally working like it should and I'm very grateful to Jose for doing such a great job. I'm recommending this business to all my friends.

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!

Ongoing problem for 9 years. Dealer repaired emissions error and check engine light returned in two weeks with same problem. AACCEL repaired the emissions, and now I can fuel the car in less than 15 minutes and pass the Will County emissions testing.
