Transmission Repair – Fluid Leaks and Faulty Solenoids

There are so many different systems that make up a car: engine, brake system, electrical system, and, of course, the transmission system. The transmission is made up of many different parts, and it is an integral part of the car. Having it replaced or rebuilt can sometimes mean big bucks for the owner of the vehicle. However, not every problem in transmission repair requires a solution that is quite that drastic. Two problems that are similar and often seem to go hand-in-hand are fluid leaks and faulty solenoids.

The fluid in the transmission is a red or pink color, sticky, and can even smell a little sweet. It is very easy to differentiate from the other fluids in the car (gas, brake fluid, antifreeze, oil, etc.) if car owners know what they are looking for. The transmission has several different parts to it- the bell housing, the gears, and the filter just to name a few. Many of the parts move the entire time the car is in a running gear and change their movements each time the person shifts and changes gear. These parts must be well lubricated in order to do this. The job of this fluid is to make sure all of the parts stay well greased so they do not grind together.

If the fluid is leaking someone will notice a large difference when they shift. It may sound “painful,” clunky, or any other down right awful noise you can think of. This can be detrimental for the transmission if the problem is left unaddressed. Not only does it become harder to shift, but metal-on-metal contact is occurring which has the potential to wear the pieces down, meaning that several parts may need to be replaced or rebuilt and that more money is going to be needed to fix it. It is much easier to address the original fluid leak quickly than to wait for the entire system to shut down.

The solenoid is also key to making sure the parts stay well lubricated. If someone goes in with low fluid levels, the transmission repair technician will also check transmission shift solenoid. The solenoid is responsible for controlling how much fluid enters the system. If it somehow becomes broken or damaged, the flow is interrupted. It will either be starved for fluid or will become flooded. Neither of the scenarios is very good. A problem with this part can lead to all of the same effects as a leak- grinding noises, slower shifting, etc.

Transmission repair, when addressed quickly, does not have to cost an absolute fortune like many people think it does. Nobody deserves to be stricken with fear whenever their mechanic says they believe they have a problem with the transmission. Tiny leaks can be spotted; a slightly malfunctioning solenoid can be repaired. Regular or routine maintenance can actually find many other problems before a car starts developing symptoms. The pieces can be replaced or repaired and all of the hassle can be completely prevented.
