Today marks six years with Michael Light.

Michael joined the Edwards Transmissions+ technician team on September 4, 2020. Since then, he has become one of the people we count on for careful diagnostics and complicated repair work.

Transmission work takes patience, skill, and attention to detail. Michael brings all three to the shop every day.

Thank you for six years of good work, Michael. We are glad you are part of the Edwards team.

Your tires lost pressure last night and you did not do anything wrong.

Tire pressure drops roughly 1 PSI for every 10-degree drop in outside temperature. Central Indiana just went from overnight lows in the 70s to overnight lows in the mid-50s. That is a real loss of about 2 PSI across your whole vehicle, and it happened while you were asleep.

Underinflated tires do three things you do not want. They wear faster on the outside edges. They reduce fuel economy. And they change how your vehicle handles in exactly the conditions fall is about to hand you: wet pavement and early morning fog.

Check your pressure cold, before you drive, first thing in the morning. The correct number is on the sticker inside your driver door jamb, not on the tire sidewall. The sidewall number is the maximum the tire can hold, not what your vehicle needs.

This is a five-minute job that most drivers skip until the dashboard light comes on. By then you have been driving under inflated for weeks.

Tech Tip Tuesday: Your Cooling System and Transmission Work Together

Most drivers think of the radiator as an engine component, but on many vehicles it also helps cool the transmission fluid.

Transmission fluid travels through a cooler built into or mounted near the radiator. If the coolant is low, the radiator is restricted, or the engine is running hot, the transmission fluid can run hotter too. Heat is hard on fluid, seals, and internal parts.

A few signs worth paying attention to:
• Shifting changes after a longer drive
• The temperature gauge climbs in traffic
• You notice a sweet coolant smell after driving

When we diagnose a transmission concern, we check the cooling system too. The two systems affect each other, and looking at both helps us find the real cause.

By the time summer ends, every transmission in Central Indiana has absorbed a season of heat, traffic, towing, and long highway drives. For most vehicles, the effects of that stress will not show up until fall or winter, when a small summer issue has had time to become a noticeable symptom.

The smart move is to get ahead of it. A transmission fluid inspection now, before the weather turns, identifies whatever the summer did. Fluid that has broken down. Seals that have started to weep. Components that have been working harder than they should.

Cold weather amplifies every one of those problems. A marginal seal in September becomes a visible leak in December.

$109 Complete Systems Analysis.

If your vehicle has a symptom you cannot quite identify, a shift that feels off, a noise that was not there last year, a warning light that comes and goes, this is the fastest way to get a real answer.

It includes a full electronic scan across drivetrain, engine, and chassis modules. Live data review under drive conditions. Visual inspection of drivetrain components and fluid. A written summary of findings with priority recommendations.

$109, flat rate. No hidden charges. You leave knowing exactly what your vehicle needs and what it does not.

Tech Tip Tuesday: Shift Solenoids

Shift solenoids are small electrically operated valves inside an automatic transmission. They control where hydraulic fluid goes, and that determines which clutch packs engage and when.

The transmission control module sends an electrical signal to a solenoid. The solenoid opens or closes a hydraulic passage in the valve body. Fluid pressure routes to the correct clutch pack. The transmission shifts. All of it happens in a fraction of a second, dozens of times during a normal drive.

Most modern transmissions have between four and eight solenoids handling different functions, including shift timing, line pressure control, and torque converter lockup.

When a solenoid fails, the symptoms are specific and usually noticeable. The transmission gets stuck in one gear. It skips a gear entirely during upshift. Shifts become harsh or delayed. The check engine light comes on with a transmission-related code. In some cases the vehicle drops into limp mode.

The good news is that solenoid failure is often one of the less expensive transmission repairs. Many are accessible by dropping the pan without removing the transmission from the vehicle.

The key is a correct diagnosis. A failing solenoid can produce symptoms that look like far more serious internal damage. Proper testing at a transmission-focused shop confirms the actual cause before any parts get replaced.

Buying a used vehicle this fall? A pre-purchase transmission inspection is one of the best $109 you can spend.

A transmission on the edge of failure can feel completely normal on a short test drive. Transmissions do not usually fail all at once. They give small signals over months or years before symptoms become obvious to a driver who is unfamiliar with the vehicle.

A specialist-level inspection catches what a test drive does not. Fluid condition and level. Evidence of slippage in scan tool data. Temperature behavior under load. Leaks, internal wear indicators, and service history visible through diagnostic channels.

The difference between a 100,000-mile vehicle with a solid transmission and a 100,000-mile vehicle that needs a rebuild within the year can run several thousand dollars. An inspection tells you which one you are looking at before you commit.

Fleet downtime is not just a repair cost. It is a revenue cost.

Every day a commercial vehicle sits out of service, it is not generating revenue. Every day a delivery van, service truck, or work van sits at a shop, the business absorbs both the repair bill and the lost productivity.

Edwards Transmissions+ works with fleet operators across Central Indiana to minimize that downtime.

We handle transmission and drivetrain service for fleets of every size, from single-owner work trucks to multi-vehicle operations. Diagnostics, scheduled service, rebuilds, and repair, all held to the same standard that built our reputation over four decades.

If your business runs vehicles and needs a transmission specialist who understands what downtime actually costs, we should talk.

44 years in Central Indiana.

Edwards Transmissions+ opened in 1982. That was before fuel injection was standard equipment. Before automatic transmissions had electronic control modules. Before a vehicle could tell its own transmission how to shift.

The technology has changed. The vehicles have changed. The diagnostic tools have changed completely. What has not changed is the standard of work that goes out our doors.

Every transmission we touch, every diagnosis we deliver, every customer who walks in gets held to the same standard we set on day one. Honest answers. Quality work. A clear path forward.

Four decades in, we still do one thing. We know transmissions.

Seven locations across Central Indiana. BBB A-rated. Specialist-level diagnostics for customers who want it done right the first time.

Tech Tip Tuesday: Transmission Mounts

The transmission mount holds the rear of the transmission in position against the vehicle's chassis. It is a simple component, usually a rubber-and-steel bushing, but its role matters more than most drivers realize.

Working correctly, the mount absorbs torque reactions, isolates driveline vibration from the cabin, and maintains proper alignment between the transmission, driveshaft, and differential.

When a mount fails, the symptoms show up in unexpected places.

A clunk during acceleration or deceleration, especially pulling away from a stop. Driveline vibration that feels more intrusive than it used to. A harsh shift that the transmission itself is not actually causing. Noise transferring into the cabin from under the vehicle.

What makes mount failure tricky is that these symptoms feel like transmission problems. Customers come in convinced the transmission is failing, when the actual issue is a rubber bushing letting the transmission move under load.

Visual inspection catches most failed mounts. Cracks, sagging, rubber separated from the metal plate, or fluid saturation from a leak above all point to a mount at the end of its service life.

This is one of the more straightforward drivetrain repairs. Missing the diagnosis is what makes it expensive.
