Hi there. Since the transmission fluid is a little dirty, I recommend replacing the fluid with the transmission filter. The torque converter will be working normally at all times and it will not cause the vehicle to slow down when...
You should have the power steering reservoir cap checked to make sure the vent on cap is not blocked. Also make sure the system is bled of excessive air in the system. Once these two things are checked then you...
It sounds like you may have a fuel pump that is not working properly or maintaining enough fuel pressure to keep the motor running. If the engine was run completely out of fuel, there is a chance this could have...
Check to see if any diagnostic trouble codes have been stored and use a real time scanner to check the response of the throttle position sensor and oxygen sensors. The throttle position sensor sends a reference voltage to your power-train...
Hello, There are a number of things that can cause this to happen, most of which may be related to the transmission control module. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle...
The noise is the parking brakes are out of adjustment and the brakes are dragging. Check the rear brakes and see if they are releasing when going in reverse. If you need further assistance with your brake system, then seek...
The brake system and nearby components should be inspected. There has to be something noticeably loose to create that obvious of a noise on braking. Were a mechanic to look closely, he or she would undoubtedly find the issue as,...
Hi There, This is completely normal for the oil pressure to increase when accelerating. The oil pressure inside the motor increases as the motor works harder. Your oil pressure switch reads this change in pressure and relays this to the...
Check to see if any diagnostic trouble codes have been stored in both the PCM and TCM. Check the fuses in the circuits that power the transmission controls. Occasionally, a short in a sensor such as an oxygen sensor will...
What you are describing is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer...
If you are attempting to complete this task on your own, I would highly recommend using the jack stands for support; as the cross-member can fall rather quickly and be difficult to hold up before both sides are removed. ...
When a low oil pressure warning is displayed, it can normally be narrowed down to one of three basic causes. An oil pressure sensor that is reading a faulty pressure, oil pressure that is actually low due to worn bearings...
Hi There, As you know, code P0332 relates to the knock sensor, which may be a result of code P0306, which relates to the crankshaft position sensor. When the crankshaft position sensor is detected to have more than a 2...
Hi there. Thanks for writing in to YourMechanic.com. Unfortunately, we do not offer mechanical repair or service on aftermarket part installations like the LED lights you are referring. It is probably best for you to contact the manufacturer of those...
Engines require more fuel to start and run properly when cold. If the fuel mixture is either too rich or too lean for cold running, the engine can run rough or even stall. The fuel mixture can be effected by...
Rear sway bars are to help the rear of the vehicle to be stable when driving around turns or maneuvers and when towing another vehicle. The sway bar should not affect the vehicle when hitting bumps unless the links or...
Hello. It sounds like the pins in the transmission female connector may have gotten bent when you pressed the connection back in. From the codes you are getting you are having connection issues. It is hard to see it but...
Hi there. Your 2004 Chevrolet Avalanche should have an anti-lock braking system; which in most cases will restrict the braking to ensure this doesn't occur. However, there are some things that will restrict the ABS from working as it should...
Hello, thank you for writing in. The traction control system and the ABS work hand in hand to help keep you on the road in slick conditions. They are both monitored heavily by the computer which makes diagnostics a lot...
Hi There, This suggests you may have a short, a faulty connection somewhere in the main harness from the lights or potentially an issue with the charging system or battery. If the battery is weak enough, this may draw enough...
