Ensure smooth shifting, reliable performance, and long life for your vehicle’s transmission system.
Transmission Repair & Maintenance in Newington, CT
Your vehicle’s transmission is one of its most complex and vital systems — handling everything from shifting gears to transmitting engine power to the wheels. Whether you’re experiencing slipping gears, delayed engagement, or fluid leaks, the experts at Mike’s Auto Service are ready. Our ASE-certified technicians use advanced diagnostics and proven repair practices to keep your transmission running smoothly.
Comprehensive Transmission Services We Offer
We cover all major transmission services — from routine maintenance to full replacements — for cars, SUVs, and light-duty trucks:
- Transmission fluid change & flush – Regular fluid service helps maintain proper lubrication, cooling, and friction management, extending transmission life.
- Filter and pan replacement – Many automatic transmissions contain internal filters; replacing them during service helps prevent sludge and wear.
- Torque converter inspection & replacement – A failing torque converter can cause shuddering, slipping, or overheating. We inspect and replace as needed.
- Clutch pack, band, and valve body service – These internal components wear over time. We replace or repair them to restore smooth shifting and internal operation.
- Leak diagnosis & seal replacement – Transmission fluid leaks lead to low fluid levels, overheating, and internal damage. We locate leaks, replace seals, and restore proper fluid containment.
- Full transmission replacement – When repair isn’t cost-effective, we offer full replacements with warranty support.
- Manual transmission service (if applicable) – From clutch replacement to gear and synchro service, we handle both automatic and manual systems.
When to Schedule Transmission Service
It’s best to follow your vehicle manufacturer’s interval for fluid change (often every 30,000–60,000 miles), but you should seek inspection immediately if you notice:
- Gears slipping, delayed engagement, or vehicle revving but not moving
- Strange noises (whining, grinding) coming from under the vehicle
- Dark or burnt-smelling transmission fluid
- Fluid leaks or low fluid levels
- Transmission warning light or check engine light related to transmission faults
Ignoring these warnings can lead to more damage, higher repair bills, or complete transmission failure. At Mike’s Auto Service, we provide a clear diagnosis, discuss your options, and perform the repair that’s right for your vehicle and budget.

Transmission FAQs
Most manufacturers recommend a fluid change every 30,000 to 60,000 miles for automatic transmissions, depending on driving conditions. Severe conditions (towing, stop-and-go) may require more frequent service.
Transmission slipping means the engine revs up but the vehicle doesn’t accelerate correspondingly. It often signals worn clutch packs, low fluid, or internal damage. Early diagnosis can prevent full failure.
Driving with a fluid leak is risky — low fluid leads to overheating, internal damage, and could leave you stranded. If you see fluid under the car or smell burnt odor, schedule a service immediately.
A replacement installs a new or remanufactured unit. We’ll review costs, benefits, and warranty options for both.
Common symptoms include delayed gear engagement, jerky or rough shifting, slipping between gears, grinding noises, burnt-smelling fluid, or a warning light on the dashboard. If you notice any of these signs, it’s time to schedule a professional inspection before the problem worsens.

Have been using Mike’s for a couple years now for emissions and oil changes and their team has been nothing but professional and courteous, on top of excellent service and pricing. This last service was a little outside their list of services on their website but as anticipated they hit it out of the park. HIGHLY recommend them!!Posted on Google
