Automatic Transmission & Manual Transmission

Is your transmission slipping or shifting hard, or a delay?  Do you hear a whining or clunking sound? Is your transmission light on?  If so you may have a transmission issue. While some of these problems might seem minor, ignoring these signs could make the problem worse and more costly to repair.   Transmission fluid beneath the car is not normal. Even the slightest drop or two can indicate a major problem in the making. If you see spots, give us a call! Far to often we see minor issues become major issues, because of vehicle owners waiting to see if a problem will go away, or miraculously fix itself.  Save yourself the big hassle and the big expense and have your vehicle inspected at the first signs.


When you need an honest, straightforward assessment of your automatic transmission or manual transmission come see Brian at A-1 Transmission Specialists.


It is often more likely for a manual transmission vehicle to need the clutch replaced, when compared to other transmission repairs. The clutch (clutch disc, pressure plate, & throwout bearings) is a “wear item” and should be serviced if it sticks or gives you any trouble shifting.

Transfer Cases

Most people are unaware of what a transfer case is, or does.   However, if you have a 4-wheel drive or an all wheel drive vehicle, then you are the proud owner of one.  So what does a transfer case do? Simply said, the transfer case receives power from the transmission and sends it to both the front and rear axles.  It makes sure you have power available for both the front and rear axles. If you have an AWD vehicle, power goes to the front wheels. If the vehicle senses the need for all four wheels, hat is when the transfer case steps in and transfers a portion of the power to the rear wheels.  This can be done with gears, hydraulics, or a chain drive.

A transfer case should be serviced periodically by draining all fluids and refilling with fresh fluid.  Even with proper maintenance, transfer case parts will eventually wear out and repairs will be necessary.  However, properly servicing your transfer case will extend the life, and give you the most out of your vehicle.


Driveline & Drivetrain

Your vehicle's driveline is a combination of several components that are separate from, but work together with, the engine and transmission to give you a smooth quiet ride.  The drivetrain, or driveline, is comprised of the driveshaft, axles, wheels, differentials and joints. All of these car components work together to steer and stabilize the vehicle.   If you are unable to steer properly, if your vehicle seems to shudder when you step on the gas, or if you hear a loud, hard noise when shifting your vehicle then there may be an issue with your driveline.  Driveline repairs often surface when there is physical or structural damage to a vehicle. Also they may need replacement due to normal wear and tear, or from age related damage, such as rusting.
