Before the school year starts, ten minutes of attention on the vehicle you use for school runs can make the rest of the year easier.

Check tire pressure and tread depth. A tire sitting at 24 psi on a cool August morning that should be at 35 handles differently, brakes differently, and wears faster.

Check your wiper blades. Fall rain in Indiana starts earlier than most people expect, and worn blades on a dark, wet morning are a real safety issue.

Check transmission fluid level and color. Fluid should be red to light brown. If it is dark brown or smells burnt, it is telling you it is due for service.

Check your brakes. Any grinding, any pulsing through the pedal, or a longer stopping distance than you remember means it is time.

None of these checks cost anything. All of them prevent the kind of morning that starts with wondering whether the vehicle is going to get the kids to school on time.

Edwards Transmissions+ offers pre-school-year inspections across our seven Central Indiana locations.

Tech Tip Tuesday: The Driveshaft

The driveshaft connects your transmission's output to the rear differential on rear-wheel drive and four-wheel drive vehicles. It transfers rotational power across the length of the vehicle, often at high speeds and under significant load.

A driveshaft looks simple from the outside, but it operates under conditions most drivers never think about. It rotates thousands of times per minute, compensates for suspension movement through the slip yoke, and absorbs torque pulses through universal joints at each end.

Driveshaft problems produce distinct symptoms. A vibration that worsens with speed but goes away in neutral. A clunk when shifting from drive to reverse. A squeaking noise from under the vehicle that changes with vehicle speed.

Driveshaft failure is rarely sudden in passenger vehicles, but it is always progressive. A worn u-joint that gets ignored becomes a broken u-joint. A broken u-joint at highway speed becomes a driveshaft that separates from the vehicle, which can cause serious damage to the transmission case and the underside of the vehicle.

August is a transition month in Central Indiana.

Kids head back to school. Commute patterns shift. Pickup lines, morning carpools, after-school activities. The vehicles that spent summer sitting in driveways are suddenly logging daily miles again.

This is the wrong month to keep ignoring a transmission that has been acting up.

A shift that has felt a little off all summer. A hesitation on cold starts that seemed like nothing. A small drip on the driveway that has not gotten worse but has not gone away either. These are the early-stage indicators that a transmission is telling you something.

Catching the problem before school starts costs less than catching it during the second week of the school year when you cannot afford to be without a vehicle.

July closes out the hot half of the year.

By the time August arrives, Central Indiana vehicles have been running through sustained summer heat for three months. That heat does not always produce immediate symptoms. Transmission fluid that has been stressed through a summer of commutes, towing, and stop-and-go traffic tends to show its age in September and October, not July.

The smart approach is a late-summer transmission inspection before the fall driving pattern shifts. Back-to-school traffic. Earlier sunsets. Cooler mornings that can reveal seal leaks winter would have hidden.

If your vehicle has been running well all summer and you want to keep it that way through fall and winter, now is a good time to have the transmission fluid evaluated.

Happy birthday to Larry Williams.

Larry joined the Edwards Transmissions+ technician team in January of this year and has been a solid addition to the crew ever since. Hope you have a great day, Larry.

Tech Tip Tuesday: The Slip Yoke

The slip yoke sits at the front of the driveshaft on most rear-wheel drive and four-wheel drive vehicles. Its job is simple but essential. It allows the driveshaft to change length slightly as the suspension moves up and down.

When a vehicle hits a bump, goes over a dip, or loads cargo that compresses the rear springs, the distance between the transmission output and the rear differential changes. The slip yoke compensates by sliding in and out of the transmission tail housing, maintaining a mechanical connection while the geometry shifts.

That sliding motion is supported by internal splines and a seal. When the splines wear or the seal fails, problems follow.

Worn slip yoke splines produce a clunk when shifting between drive and reverse, sometimes with a driveline vibration at low speeds. A failed seal produces transmission fluid leaking from the rear of the transmission, right where the driveshaft enters.

Both repairs can be addressed without a full teardown when caught early. Ignoring either one leads to more significant and more expensive damage over time.

Happy birthday to Robert Oetman!

Robert has been part of the Edwards Transmissions+ technician team for over four years. Thirty is worth recognizing, and so is the kind of steady, skilled work Robert brings to this shop every day.

Have a great one, Robert.

Summer is peak towing season in Central Indiana, and the transmission is the component most affected by it.

Towing changes the thermal load on a transmission dramatically. Under normal driving, transmission fluid might peak at 200 degrees. Towing a boat, a camper, or a loaded trailer in 90-degree heat can push that to 240 or higher on grades or in slow traffic. At that temperature, fluid life is cut by more than half.

Three things that make a measurable difference for towing vehicles.

Use tow/haul mode when available. Most modern vehicles have a tow/haul button that adjusts shift points, increases line pressure, and applies torque converter lockup earlier. It exists precisely for this.

Shift out of overdrive on sustained grades. Overdrive gears produce more slippage inside the torque converter, which generates heat. On a long hill with a trailer, dropping to the next lower gear is the right call.

Have transmission fluid checked before and after towing season. Fluid that has been through multiple heavy towing events needs to be evaluated.

Tech Tip Tuesday: Line Pressure

Line pressure is the main hydraulic pressure inside an automatic transmission. It is what actuates every clutch pack, holds every band, and controls every shift. Without proper line pressure, the transmission cannot operate.

The pump generates line pressure. The valve body regulates it. The pressure control solenoid adjusts it in real time based on signals from the transmission control module.

Line pressure is not constant. It rises under heavy load, during hard acceleration, and in reverse. It falls during light-throttle cruising and low-load conditions.

When line pressure is wrong, the transmission protests. Pressure that is too low causes slippage, where engine RPM rises without a matching increase in vehicle speed. Pressure that is too high causes harsh, slamming shifts.

Diagnosing line pressure problems requires a pressure gauge and factory specifications across different operating conditions. A scan tool alone cannot tell you what is happening inside the hydraulic circuit.

If your vehicle has had any shifting symptoms this summer and you are not sure what is causing them, the $109 Complete Systems Analysis 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.
