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.

My A/C started blowing warm air and Honda quoted me $3800 to repair the condenser, A/C lines, O-rings, and recharge. I spoke to Trent and he advised me to bring my Honda Pilot in for him to asses and he was honest and thorough. Come to find out the A/C lines were fine and I was able to get my A/C fixed for $1500 and a 3 year/36,000 mile warranty thanks to Mike's Auto Repair. Will definitely be coming back for all my future repairs, great staff and service!Posted on GoogleJim K12 days agoWhenever I call for an appointment for an oil change they were always there to serve us. If I needed a ride home I was able to get a ride home. I wouldn't go to any other auto mechanic then Mike's Auto.Posted on GoogleHalo A13 days agoGenuinely loved my experience initially went in for emission testing and the prompt service along with the technician being so pleasant convinced me that this is where I need to bring my vehicle . I had multiple problems with my vehicle and was kinda worried having it on the road but now OMG it’s the sweetest ride ever , it cost a pretty penny but it was worth it .10/10Posted on GoogleCarlos M27 days agoI went for an emission test. It was a walk in, only 30 minutes before closing, and yet they helped me with a smile. Service was fast and professional. Very clean place, even their bathroom was spotless!Posted on GoogleSpatty D39 days agoAppreciate that they are willing to work with you to save on costs.Posted on GoogleRobert P42 days agoI’ve been a customer of Mike’s for years. One car is 26 years old and the other is 12 so they must be doing something right.Posted on GoogleJoan S49 days agoThey thoroughly checked my car. And fixed everything. Very fair prices. Excellent job. Mikes Auto is the best. I've been burnt by other companies. But they are honest. Tell me everything i need b4 they do anything. They go above and beyond. This is the only place I will have my car worked on. They're all very kind and friendly.Posted on GoogleEm M49 days agoI can't say enough good things about this shop. I have brought my 4runner into them a few times. They just repaired my transmission lines by fabricating them, themselves. That says a lot about the effort they are willing to put in. As a car girl, myself i know those lines can be a royal pain! These guys are very honest and trustworthy. They don't treat me like a dummy being a woman as other places have tried to do to me in the past. They are very efficient and fair. I feel very confident with my vehicle in their hands. I will not go anywhere else for future work that may need to be done. I highly recommend them, always! Thank you to the wonderful team for getting my baby fixed timely! Appreciate all of you and the quality work you do.Posted on GoogleErika M50 days agoMike’s Auto is the only place I’ll bring my vehicle. I can’t recommend them enough! Colby was amazing. Not only did he save me nearly $15,000, but he also arranged and paid for Lyfts to and from my house without charging me a single cent. I recently brought my car in because the RPMs were spiking on the highway, and I also needed an oil change. They paid for a Lyft to take me home while they inspected the vehicle. After diagnosing the issue, Colby informed me that my powertrain was still under warranty and explained that the dealership would fix the problem and even perform the oil change at no cost. They easily could have completed the oil change I originally requested and charged me for it, but instead they were completely honest and pointed me in the right direction. Even though they didn’t charge me for anything, Colby still arranged and paid for another Lyft to bring me back to the shop. Their customer service is outstanding, and they’re truly an honest business that puts their customers first. If you’re looking for a trustworthy mechanic, Mike’s Auto is the place to go.Posted on GoogleJohn S54 days agoThree dealers failed to properly diagnose a fuel pump and fuel pressure sensor issue. Then i met Colby at Mikes Auto . Colby said his repair shop was better then the rest . Well he was right . He worked with my warranty company diagnosed and fixed issue service lights are off . I recomnend Mikes to anyone
