What are the causes of transmission jerking in a Cadillac SRX?

Cadillac SRX transmission jerking causes: 1. Transmission control module (TCM) failure: The TCM acts as the central control unit of the transmission, responsible for communicating with the vehicle's main computer, collecting signals, and issuing commands. Most TCM failures occur in the command-issuing function. 2. Solenoid valve issues: Each solenoid valve contains a small valve core that operates via electrical current, similar to the working valves in the valve body. This can cause unstable oil pressure regulation and uneven shifting. 3. Contaminated valve body: The valve body requires an extremely clean working environment. Any contamination, even fine powder, can affect the smooth operation of the shift valves inside. 4. Oil pressure sensor problems: The sensor collects data and sends it to the TCM, which then issues commands to the solenoid valves. If the collected data is incorrect, the resulting pressure regulation will also be wrong.

How to Lower High Idle Speed?

High idle speed can be adjusted at professional repair shops or 4S stores. Below is relevant information about high idle speed: 1. Causes: Mainly include damaged intake sensors, excessive vehicle air intake, faulty water temperature sensors (where the vehicle increases idle speed to raise water temperature), and throttle position sensor malfunctions. 2. Hazards: Prolonged idling can easily lead to carbon buildup. Since the car operates in a rich fuel injection state during idling, the injector sprays highly concentrated fuel to ensure engine operation. Therefore, idling itself is more likely to cause carbon buildup compared to driving or highway speeds. Extended idling can result in severe engine carbon deposits.

What Causes Transmission Fluid to Increase?

Transmissions have vent holes that allow moisture from the air to enter, which can then degrade the transmission fluid. This is why transmission fluid needs to be replaced periodically. Below is more information about transmission fluid replacement: 1. Introduction: Transmission fluid is used in automotive transmissions to clean and lubricate the gear system, extend the lifespan of the transmission components, and provides functions such as cleaning, lubrication, rust prevention, and heat dissipation. 2. Types: Depending on the type of vehicle transmission, transmission fluid can be categorized into manual transmission fluid and automatic transmission fluid. 3. Replacement Interval: Generally, it should be replaced every 3 years or approximately 100,000 kilometers.
