They always do a great job on the repairs, offered at a great price, and they get the repairs done quickly… A personal thank you to the owner/manager Quenton for getting my car in when I needed the repairs done quickly.

I've been to Rad Air before and was happy with the service… an oil change place couldn't remove the bolts to get the skid plate off my vehicle. I took it to Rad Air and they didn't charge extra for that. I'll use them again.

Akron Engine & Transmission FAQs

Where can I get transmission or engine repair near me in Akron?
If you're searching for transmission or engine repair near you, Rad Air is at 1200 West Portage Trail in Akron's Merriman Valley — serving Cuyahoga Falls, Tallmadge, Stow and all of Summit County. Our shop is known for heavy-duty engine and transmission work, with free estimates and loaner vehicles available.
What are the signs of transmission problems?
Common signs of transmission trouble include slipping or revving between gears, hard or delayed shifts, grinding or shaking, a burning smell, or red fluid leaking under your car. If you notice any of these, have it checked before it becomes a costly repair.
Why is my check engine light on?
A check engine light can mean anything from a loose gas cap to a failing sensor, a misfire, or a transmission issue. Rad Air Akron runs a full diagnostic to read the trouble codes and pinpoint the real cause before recommending any repair.
How much does transmission repair cost?
Transmission repair cost depends on the problem — a fluid service or minor repair costs far less than a full rebuild or replacement. Rad Air Akron diagnoses the issue first, gives you an upfront estimate, and offers financing for larger transmission and engine jobs.
Should I repair, rebuild, or replace my transmission?
It depends on the damage and your vehicle's value. Minor issues are often repairable, while severe internal failure may call for a rebuild or replacement. We show you the options and costs honestly so you can choose what makes sense — we won't push unnecessary work.
What does a transmission fluid leak look like?
Transmission fluid is usually red or brown and leaves a slick spot under the middle of your car. Low or burnt fluid causes slipping and overheating, so it's worth fixing early. We find the source of the leak and service your fluid.
Do you repair engines and transmissions on all makes, including hybrids?
Yes. Our ASE-certified technicians repair engines and transmissions on all makes and models, and our Akron shop is home to Cleveland Hybrid for hybrid and electric vehicle drivetrains. From head gaskets to full rebuilds, we handle work many shops send out.
Do you warranty engine and transmission repairs?
Yes. Engine and transmission work is backed by our 36-month/36,000-mile (whichever comes first) parts and labor warranty, and parts like a new gear box are covered by our Fixed for Life limited lifetime warranty. We also work with most extended warranty companies. See our full warranty for details.
