Technical Tuesday 🔧

Why do newer cars have 8, 9, even 10 gears when older ones got by with 3 or 4?

Think of gears like the gears on a bicycle. When you've got only a few, the engine has to work harder, or spin faster, than it really wants to in between. With more gears, the transmission can keep the engine in its comfortable sweet spot more of the time, whether you're pulling away from a stoplight on Michigan St or cruising down the highway. That usually means better gas mileage and a quieter ride at highway speed.

There's a trade-off, though. More gears means more shifts, and the transmission is working a little harder behind the scenes to pick the right one. That's why fresh, clean fluid matters so much on these newer designs, and why a software update can sometimes smooth out a shift that feels off.

Did You Know? The first automatic transmissions in the 1940s had just 2 or 3 speeds. Many of today's pickups and SUVs have 8 to 10.

Technical Tuesday 🔧

Your car might update itself overnight — here's what that actually means.

Modern vehicles from Ford, GM, and several other manufacturers can now receive over-the-air (OTA) software updates — similar to how your phone downloads new software while you sleep. These updates can fix bugs, improve fuel economy, and even change how your engine or transmission responds. Sounds great, right?

Here's the part that surprises a lot of people: not every update goes smoothly. Some OTA updates have caused real-world issues — transmission shift hesitation, dashboard warning lights, rough idle, or even a no-start condition — because the new software changed calibration settings that were working just fine before. A vehicle that ran perfectly on Monday can behave oddly by Wednesday for no obvious reason.

When that happens, the fix is a proper software reflash — applying the correct, verified calibration using manufacturer-level equipment. At Precision Transmission, we handle Ford and GM software updates right here in our shop. No sending your vehicle somewhere else, no waiting around.

Did You Know? GM has issued Technical Service Bulletins (TSBs) specifically addressing problems caused by OTA update errors. In other words, sometimes the fix for a bad software update is another software update — done correctly, by a shop with the right tools.

Questions about your vehicle? Give us a call at Precision Transmission — 574-282-2806.

My car overheated on the highway. I told it to cool it. It did not appreciate the advice.

Overheating is no joke, even if the joke writes itself. Coolant system issues can cause real damage fast. If your temperature gauge has been creeping up, come see us before things get too heated.

I asked the mechanic how long my oil change would take. He said, "Depends on how long you can wait." I'd been there so long I started reading magazines from three years ago.

We know your time is valuable. That is why we do our best to get you in and out without any surprises. Oil changes are quick around here, we promise.

My car's been making a strange noise for weeks. Turns out it just wanted to be heard.

We hear that. Strange noises are your car's way of telling you something is off. The sooner you listen, the simpler the fix usually is. Give us a call and we will help you sort it out.

Fun Fact Friday!

The world record for highest mileage on a single car belongs to a 1966 Volvo P1800 that surpassed 3 million miles — all on the same engine, with consistent, careful maintenance. Most vehicles will never come close to that number, but the lesson holds: regular maintenance is what separates a car that lasts from one that does not. We have been helping South Bend drivers keep their vehicles on the road since 1978, and that is still what we are here for.

Why did the car refuse to leave the DMV parking lot?

It finally had something in common with everyone inside — it had no idea how long it was going to be there.

And you know what they say: the DMV waiting room and a slipping transmission have a lot in common. Both will leave you wondering if today is really the day things are going to move.

We hope that gave you a smile this Monday. If your car is putting you through its own kind of waiting game, give us a call — we will get things moving again.

The mechanic said my car had a leak. I said, "Can you keep a secret?" He said no. Neither could my car.

Fluid leaks have a way of making themselves known one way or another. Better to find them early than to let them find you at the worst time. We are here when you need us.
