The T-5 is a five-speed automotive transmission manufactured by Transmissions Technologies Corporations (TREMEC) for Ford Motor Company. The transmission is used in passenger cars, SUVs and light trucks. It was first introduced in 1981 for use in the AMC Spirit/Concord. The two types of T-5 transmissions are World Class and Non World Class. Today the transmission is used in the Ford Mustang GT. It is also sold as an aftermarket part for use in classic car restoration.

Weight

The weight of the transmission is 75 pounds for both cars and light trucks. The transmission housings are made of die-cast aluminum in order to reduce the total weight.

Gear Ratio

The gear ratio for T-5 car transmissions can range from 2.95-to-1 to 3.75-to-1 for first gear, from 1.94-to-1 to 2.19-to-1 for second gear and from 1.29-to-1 to 1.41-to-1 for third gear. It is 1-to-1 for all models for fourth gear, and ranges from .08-to-1 to 0.72-to-1 for fifth gear and from 2.76-to-1 to 3.53-to-1 in reverse. For light trucks, the gear ratio can range from 3.35-to-1 to 4.03-to-1 for first gear, 1.99-to-1 to 2.37-to-1 for second gear and 1.33-to-1 to 1.49-to-1 for third gear. It is 1-to-1 for all models for fourth gear, and ranges from 72-to-1 to .86-to-1 for fifth gear and 3.71-to-1 to 3.76-to-1 for reverse.

Lower Counter Gears

The lower counter gears for the Non World Class transmissions produced in 1983 spin on cylindrical bearings that are in a straight configuration. These bearings have a thrust washer for support when they are under load. The lower counter gears of the 1985 Word Class transmissions have tapered bearings. These bearings replace the thrust washer of the earlier version.

Synchronizer Rings

Non World Class T-5 transmissions have solid bronze synchronizer rings. These rings are different sizes than the rings in the World Class T-5. On the World Class transmission, the synchronizer rings on the main shaft are fiber-lined steel. This material improved the friction surface of the rings, which slows the gear quickly, allowing for smoother shifts. The fifth gear ring is bronze. From 1990 to 1993, the ring linings on the V8 T-5 were changed to carbon fiber. This improvement in surface friction resulted in higher rpm shifts.

Other Specifications

The World Class T-5 was introduced in 1993. Its maximum horsepower is 450 under non-racing conditions. Based on 100,000 mile usage, the torque rating is 330 foot-pounds.

Vehicle lifter noise on start-up may be caused by several factors, depending on the type of oil filter, oil, lubrication system, mileage, mechanical condition and even required adjustments of your vehicle. Whatever the cause, there are some adjustments you can perform to quiet the lifters on start-up. Always start your diagnosis with the most common cause. In most cases, you will be able to fix your noisy lifters replacing a minimum of components or performing a few maintenance tasks.

Instructions

1

Take your car for a 20 minute drive on the highway to bring the engine up to operating temperature. Return to your driveway, open the hood and pull out the engine oil dipstick. Check the oil level and condition. If the oil is a quart lower from the required level or your engine is running on dirty, old oil, this may cause your lifters to tick. Add new enough oil to bring the amount to the correct level or replace the oil as necessary.

2

Make sure you are using an oil filter equipped with an anti-drainback valve (ADBV). This valve prevents the oil moving around the top of the engine from flowing back into the oil pan after shutting off the engine. This ensures that the engine, including your lifters, have oil during start up. A lifter that has provided your engine with miles of service will definitely benefit from a check-valve oil filter.

3

Take your vehicle to an auto shop and have them check engine oil pressure. If oil pressure is starting to drop, a worn out oil pump, clogged oil pickup screen, restricted oil pickup tube or oil galleries may be behind this problem.

4

Ask your mechanic to inspect the condition of the oil passages inside the engine. If you have failed to replace the engine oil at the recommended manufacturer intervals for some time, the inside of the engine might be covered with oil residue and gum, preventing proper oil flow. Take your vehicle to an auto shop and have them check oil pressure and engine mechanical condition.

5

Check the valve clearance in your engine. On some vehicle models, manufacturers advice adjusting valve clearance at recommended maintenance intervals. This will prevent excessive part wear and valve train noise. Consult your car service manual or call your local dealer, if necessary.

A brake light switch, located on a bracket mounted directly in front of the brake pedal arm, controls your 1993 Nissan Quests brake lights. As the pedal arm pushes forward from the force of you stepping on the brakes, it depresses the switch and activates the brake lights. When the switch short circuits, it will either leave the lights always on or always off. In order to get the lights off, and return them to normal functionality, youll need to replace the faulty brake light switch. If you have mechanical aptitude and 25 minutes of time on your hands, you can fix this problem.

Instructions

1

Open the Quests front door. Adjust the drivers seat as far back as it will go in order to provide yourself with sufficient room to access the under-dash area.

2

Shine the work light in the drivers foot well so it illuminates the area at the top of the brake pedal arm. Retract the retaining tab on the brake light wiring pigtail with your thumb while gripping the pigtail with your foinger. Pull the pigtail off the brake light switch.

3

Unbolt the faulty brake light switch from the mounting bracket using a box wrench. Discard the faulty brake light switch.

4

Set the new brake light switch into the bracket. Bolt it in with the box wrench. Plug the wiring pigtail into the new brake light switch by hand.

5

Depress the brake pedal and have your helper verify the brake lights work before driving your Nissan Quest.

If you have lost the keys that came with your Dodge truck, you can contact a locksmith and they can attempt to cut a new key for you. However, they usually replace the lock cylinder in the doors and in the steering column. This can cost hundreds of dollars. There is a simpler and less expensive way to replace the key for your Dodge pickup truck.

Instructions

1

Locate the vehicle identification number (VIN) by looking at the dash through the lower corner of the window on the drivers side of the vehicle. The VIN number is also on your vehicle title, insurance card and registration card.

2

Contact your local Dodge dealership and confirm that they have the ability to cut you a new key. Most dealerships offer repair services.

3

Take your VIN number to the dealership. They can use the VIN number to look up the key code needed to duplicate your key.

Catalytic converters are used to clean up car exhaust by burning left over fuel, not burned by the engine. They use particular properties of precious metals to catalyze the burning of hydrocarbons at temperatures below their normal ignition point. These precious metals include palladium, platinum, and rhodium.

The Facts

Catalytic converters were first installed into cars approximately 30 years ago. Prior to this, no emission regulations existed and cars put out a lot of pollutants into the atmosphere. California was the first state to begin monitoring emission levels and the first law appeared in 1968. In the early 1970s, the federal government also began to monitor and impose strict regulations on emissions. As a result, today cars are 99 percent cleaner.

Introduction

The cars exhaust is cleaner, the closer the ratio of fuel vapor to oxygen is kept to the perfect ratio of 14.7:1. This ratio is hard to maintain due to the vehicles fuel/ignition system and its range of operations. If the fuel is too rich, the emissions exit the engine through the exhaust and include chemicals such as nitrogen, carbon dioxide, and water vapor. Furthermore, the chemicals mix to form carbon monoxide, hydrocarbons and other volatile organic compounds.

Function

Catalytic converters have been developed and are installed into cars to chemically alter the emissions that leave the exhaust into more environmentally friendly chemical compounds. This is accomplished with the use of the reduction catalyst (a large surface coated with a catalyst). The surface area is located within the converter and is made as large as possible through the use of layers and honeycomb like structures. These metallic structures affect the largest possible volume of exhaust gas in the shortest period of time.

Features

The exhaust gas comes in contact with the catalyst, within the converter. The catalyst metal has a unique property of being able to break the nitrogen atom from the pollutant molecule and free the oxygen atom. As a result, nitrogen atoms bond with other nitrogen atoms on the catalyst and are later emitted into the atmosphere.This type of emission is considered clean.

Considerations

Catalytic converters only work at high temperatures because otherwise the chemical reaction discussed above will not happen. As a result, they get very hot and require a specifically designed heat shield. This heat shield protects the bottom of the car and any flammable materials underneath (on the road).

Trying to work with an O2 sensor without the proper tools may result in a myriad of problems. An oxygen sensor plays an important role as it measures the amount of oxygen in both the gas or liquid that the sensor is analyzing. Should a problem arise with the O2 sensor and it needs to be repaired or replaced, the importance of having the appropriate O2 sensor tools on hand increases significantly.

Oxygen Sensor Wrench

Reaching an oxygen sensor is often a challenge as it is generally located in a hard-to-reach space. The oxygen sensor wrench was created for just this purpose, as it is capable of replacing and installing new oxygen sensors, or simply giving the oxygen sensor a "checkup." Oxygen sensors wrenches are generally 22 mm, and vary in style based on what tool is needed for a particular O2 sensor (such as rusty or overheated sensors).

Oxygen Sensor Tester

The oxygen sensor tester tool measures the response time of the O2 sensor. If the O2 sensor, when tested, is unable to move from under 175mV to over 800mV in under 100mS upon snapping the throttle, then the test is failed, indicating the need for a new O2 sensor.

Oxygen Sensor Socket

The oxygen sensor socket tool is specifically designed to assist in removing the O2 sensor from the exhaust manifold. Alternatively, a 22-mm socket may be used if you are unable to acquire an oxygen sensor socket. The socket is placed over the O2 sensor and turned clockwise to loosen it, with heat (via letting the car warm for five minutes) and oil applied if you are unable to loosen it.

A Dana 44 is a type of automotive axle manufactured by Dana Corporation and used by many automobile manufacturers. The Dana 44 Axle for a Scout II is made specific for a Jeep. These axles can be installed on the Jeep, but often they need to be cut down to fit properly. If you are planning on installing a Dana axle for a Scout II, you may need to cut it down so it will fit.

Instructions

1

Run a tape measure along the length of the Scout II Dana 44 axle. It should measure 58 inches in length. This signifies it is the proper axle.

2

Lay down on the ground near the front of the Jeep and measure the distance across the front axle. This is where the new Dana 44 axle will be installed. Record the measurement.

3

Run a tape measure along the new Dana 44 axle and draw a small line along the axle with a black marker at the desired cut location so it will fit onto the Jeep.

4

Press the blade of an angle grinder up to the mark on the axle where you will be cutting. Put on gloves and safety goggles for added protection. Hold the arm coming out of the side of the angle grinder with your dominant hand and the back with your non-dominant hand.

5

Flip the switch to turn on the angle grinder and press it firmly into the metal. Cut caully along the black mark. Press down on the grinder so it does not move right or left when you are cutting and continue until the piece has been cut in two.
