Automatic Transmissions shift between gears automatically to optimize driving, and changes gears based on the driver’s throttle pedal, vehicle speed, engine speed, and vehicle load. Typical automatic transmissions have 4-5 forward gear ratios, a Reverse, Park, and Neutral gear. Shifting gears occur automatically once the car is in Drive. Automatic transmission repair is complicated based on all the components that make it up, and you need to have any automatic transmission issues properly assessed by auto mechanics.
There are clutches in both automatic and manual transmission cars, and different types of clutches. When shifting gears, the clutch engages and disengages from the flywheel and transfers the torque through the transmission. Clutches should help your vehicle start and shift gears smoothly. The clutch in your car receives a lot of wear and can eventually wear out. If your clutch begins slipping irregularly or is making noises that are raising suspicion, contact us for a free estimate.
Four Wheel Drive Transmission
A four-wheel (4×4) drive vehicle has differential gears, both front and rear axles, and a transfer case attached to the transmission. Four-wheel drive vehicles demand maintenance on the transfer case, front differentials, rear differentials, and transmission fluids.
Front Wheel Drive Transmission
If your vehicle has Front-wheel drive, the engine drives the front wheels only. The power is routed through the transmission to the final drive where it is split and sent to the two front wheels through the drive axles. The engine, transmission, and additional hardware is all located in the front of the car.
Driving a vehicle with a Manual Transmission requires using the clutch pedal and gear shift to manually shift gears based on the speed of the vehicle. Manual transmissions have been built with anywhere from two to eight gears. Front-wheel drive and rear-wheel drive are the two main configurations for manual transmissions. Typically, manual transmissions require less maintenance then automatic transmissions.

Automatic and Standard Transmission
Manual and Automatic Transmission
What is better? Manual or automatic? How do they work?
Manual transmissions cost less than automatics to begin with. When you go to a car dealer you will notice that the stick-shift version of the same model is cheaper.
Any mechanic can tell you that working on a manual transmission is much easier than working with automatic gear boxes. So the repair costs for automatics are significantly higher.
Manuals – if properly operated – will go hundreds of thousands of miles without problems. The lubricant needs to be replaced periodically but not as frequently as in automatics.
Standards are harder to drive. Shifting while keeping your hand and eyes on the road seems to be harder for some individuals, while others seem to enjoy the shifting.
Manual gear shift
The main difference in operating a car with a stick shift vs. one with automatic transmission is that you need to shift gears based on the vehicle’s speed and this requires the use of the clutch pedal and the gear shift (stick). When the clutch pedal is depressed the clutch is disengaged – the engine and the transmission is separated. Gears can be selected at this time or the car can be stopped without stalling.
It’s not depressing the clutch pedal that takes practice – releasing it requires practice to ensure a smooth start and gradual transition between gears once the vehicle is in motion. If the clutch pedal is not properly used the car will jump and often stall. Learning to control the clutch pedal is the single most frightening part of driving standards and many people become discouraged after a few unsuccessful trials.
Automatics also have a clutch except instead of a clutch pedal a torque converter is used to separate the engine from the transmission – and it all happens automatically without the need of driver input.
4 x 4 Transfer Case
The heart of an off road 4x4 might be the engine but it’s the transfer case that gets power to the axles! And with all the transfer cases out there, how do you know which is the right one for you? Brad will review the benefits of the most commonly used t-cases, their most popular upgrades.
The transfer case is a 4x4 drivetrain component that’s mounted behind the transmission. Its job is to receive engine torque from the transmission and then distribute that torque to the axles by way of driveshafts. The transfer case sends all the torque to the rear axle in 2WD, but splits the torque between the front and rear in 4WD. Full-time 2WD vehicles don’t use a transfer case, because all the torque is always sent directly to one axle.
A transfer case can be driven by chains or by gears. Chains are more common, primarily because they’re quieter and lighter. Some hardcore off road drivers prefer gear-driven transfer cases, however, because they’re more durable.
Types of transfer cases
A transfer case can full-time, part-time, or some combination of the two. A full-time transfer case is always in 4WD. To balance the requirements of street driving with off-road driving, full-time transfer cases generally allow some slip between front and rear wheels, plus some means of temporarily locking the slip.
Most truck transfer cases allow the driver to switch between 2WD and 4WD, based on the conditions and driving surface. You would use 2WD on high-traction surfaces to minimize wear on your front drivetrain components, improve gas mileage, and realize better handling. Additionally, a truck transfer case typically has high and low gearing. The low-range setting sends more torque to the wheels for improved crawling and towing performance. One-speed transfer cases are usually reserved for all-wheel-drive vehicles.
Some manufacturers, including Jeep, also produce hybrid truck transfer cases that incorporate settings for 2WD, full-time 4WD, and part-time 4WD.
Reasons to upgrade your truck transfer case
You may need to upgrade or modify your truck transfer case to improve your off road performance or to adjust for other changes you’ve made to the vehicle. For example, a replacement transfer case can give you more appropriate gearing, plus added strength. You could also improve your gearing by using an adapter to stack a second transfer case, or by installing a crawler box. The crawler box goes between the transmission and transfer case and adds a low-range gear that can be used with your factory low-range gear. Another potential upgrade is converting your full-time 4WD truck into a part-time 4WD using an aftermarket transfer case conversion kit.
Since a transfer case is designed to handle certain torque levels, many popular 4x4 modifications may warrant a transfer case upgrade. Obviously, this includes any project that significantly increases your rig’s horsepower and torque. But even the installation of larger tires and wheels will put added strain on your factory transfer case.
Differentials & Axles
In automobiles, a differential couples the input shaft to the Pinion, which in turn runs on the Crown wheel of the diff. This also works as reduction gearing to give the ratio. On rear wheel drive vehicles the diff may connect to half-shafts inside an axle casing or drive shafts that connect to the rear driving wheels. Front wheel drive vehicles tend to have the pinion on the end of the main-shaft of the gearbox and the diff is enclosed in the same casing as the gearbox. They have individual drive-shafts to each wheel. Older 4x4 vehicles and tractors usually have a solid front axle, the modern way can be a separate diff and driveshaft arrangement for the front. The differential gearing allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when the vehicle turns, making the wheel that is travelling around the outside of the turning curve roll farther and faster than the other. Average of the rotational speed of the two driving wheel equals the input rotational speed of the drive shaft. An increase in the speed of one wheel is balanced by a decrease in the speed of the other.
A differential consists of one input, the drive shaft, and two outputs which are the two drive wheels, however the rotation of the drive wheels are coupled by their connection to the roadway. Under normal conditions, with small tyre slip.
