How to Diagnose Automatic Transmission Problems

 · You may also notice that your car may have a problem engaging some gears, and therefore it will skip to the next gear. This is a big sign that you have transmission shift solenoid problems because you have one or more shift solenoid for each gear, and if one is broken, it will not shift to that gear

A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive ... · How Much Does It Cost? The cost for low engine power will depend on what is found after a list of troubleshooting check points have been performed. If you were to have a repair garage check out a low power issue they will charge between 1 and 2 hours of labor or ... · If your car's transmission speed sensor malfunctions or fails, you can expect to experience one or more of the following symptoms: Faulty Cruise Control. If your car is equipped with cruise control, this functionality is usually one of the first things to suffer when ….

How Does a Torque Converter Work?

 · Welcome back to Gearhead 101 — a series on the basics of how cars work for the automotive neophytes out there. If you've been following Gearhead 101, you know how a car engine works, how the engine transfers the power it generates via the drivetrain, and how a manual transmission functions as sort of a power switchboard between the engine and the drivetrain.Causes of Diesel Engine Smoke - By Color A brand new diesel engine running at full load will experience a little bit of blow-by upon startup. Blow-by is a condition where diesel fuel, air and vapor are pushed past the rings into the crankcase of the engine. Correct ... · Low fluid results in low pressure, which means the torque converter can't do its job. Additionally, low fluid can cause the torque converter to malfunction. If the converter is overheating, it won't be able to transfer power from the engine to the transmission.

DIY Diagnosis: Causes of Low Engine Power

 · Torque converter All modern automatic transmissions have torque converters, and all torque converters have a "stall" characteristic (the maximum engine speed before the engine stalls or the car moves). There is no such thing as a "stall converter". · If more torque is needed, especially in heavy digging applications, both the low- and high-speed motors will receive flow. This provides low-speed, high-torque output from the motors, Stark says. · When I drive the car is fine but when I have one or two passengers the car struggles to move as fast it moves really slow. And I was going up hill, I floored it and it won't go about 20mph. And also sometimes the car struggles a little to stay so I have to put my foot on the gas to get the car to start.

maintenance

How long do transmissions last? It's a big question and one that's actually quite difficult to answer. Factors such as maintenance and build quality play a role. Lubrication and heat are also parts of the equation, as are circumstance and fate. It's a heady mix but it ...A. Planetary gear set. B. Oil pump. C. Output shaft. D. Torque converter. 22. Answer A is wrong. The most likely answer is the transmission pump. Answer B is correct. A worn transmission pump makes a whining noise that increases with engine speed in all gears, including park and neutral. · Hydraulic oil does not expand, when hot. the air trapped in the oil expands. the trans oil level lowers when engine is running as the oil is drawn up onto the gears. the level rises when trans is cold, as the oil runs off the gears.

Torque Converter : Operation Principle and Applications

 · If the gauge climbs at high idle you have low oil flow to the torque converter. Likely the seals on the tube feeding the trans valve at the RH rear corner of the trans. Clean and remove the top plate to check, start and you will see oil coming out. Common cause of overheating. Later Bob. Last edited: Jul 1, . · If your car's transmission speed sensor malfunctions or fails, you can expect to experience one or more of the following symptoms: Faulty Cruise Control. If your car is equipped with cruise control, this functionality is usually one of the first things to suffer when … · The torque converter plays a significant role in transmitting the torque of the engine during the process of multiplication (converter) and coupling (lock-up). In lower gear ratios, the torque multiplication mode allows the vehicle to accelerate, and then by speeding up the vehicle, in higher gear ratios, the engine and the transmission are mechanically linked via the lock-up clutch.

Understanding Torque Converters Part 2

 · ZF Friedrichshafen AG also make the industry standard automatic transmissions for urban route buses - something like 90% of urban route buses made since the mid s have a ZF 4, 5 or more recently, 6 speed auto. They also make axles, steering and suspension components for heavy vehicles. User # posts. · The definitive answer is - maybe. According to Marty, "Diameter is king in designing efficient power transfer, but there is a great deal more to stall speed than just diameter.". The torque converter is a hydraulic transfer of power to the rear wheels, unless using lock up, which then makes it a mechanical transfer.Building converters isn't for the faint of heart or the casual enthusiast, as torque converter welding machines run over $25,000 each. HMM:Matt, we have been told that a lot of upgrades can be done to an existing converter to improve the performance characteristics of it.

TEMPERATURE EFFECTS ON MOTOR PERFORMANCE

I own a 955 (early 70's). The problem I have is the unit will not change gears and does not have any "guts". I have already rebuilt the torque converter and checked both pumps that are run by the converter. Why is there only little power? Thank you, XXXXX XXXXXIn the high stall speed mode, the converter stalls at about RPM but it DOES NOT multiply torque. If you have a large displacement engine with a lot of low RPM torque, this works well. If you have a smaller engine, or an engine with a very long cam which doesn't start to make much torque below RPM then you will probably be disappointed with the dual pitch converter.When applying DC motors to any type of application, temperature effects need to be considered in order to properly apply the motor. Performance will change as the motor temperature changes. When reviewing DC motor curves, the user needs to ask the question.

Olds FAQ

I have a JCB 214 and have a trnsmission problem. It will work for two or three hours then transmission gets hot and will not move forward or back. I have changed oil,filter and checked cooler lines. I have checked for blockage in lines to cooler and have taken the ...When applying DC motors to any type of application, temperature effects need to be considered in order to properly apply the motor.
