In motor vehicles, the transmission generally is connected to the engine crankshaft via a flywheel and/or clutch and/or fluid coupling, shifting gears to dynamically change the speed-torque ratio in order to deliver power to the wheels in an efficient manner based on the speed of the vehicle, because a high rotational speed engines output cannot be used for low speeds and starting. Thus, once the transmission breaks down, the vehicle will be in big trouble.


There are a number of signs showing the breakdown of the transmission, just like falling out of gear while driving, grinding sound when changing gears, burning odor and leaking transmission fluid. Once you encounter such things, you may have your transmission replaced or rebuilt. A full transmission replacement is one of the most expensive procedures a mechanic can perform on a vehicle. However, the good news is that getting the transmission rebuilt can be much cheaper as long as there are no major issues to be addressed. Well, how can the transmission, the very complex engine component be rebuilt?


Well, the process of rebuilding a transmission is rather lengthy and labor-intensive in that the mechanics must disassemble the transmission to look for problems and replace the parts that are causing it not to function properly. Generally speaking, there are two steps before rebuilding a transmission. The first is changing the transmission fluid, for this is the easiest check and one of the common problems causing the transmission breakdown—The dirty transmission fluid will cause the shifting to become noticeably “stickier” and decreasing the vehicle’s fuel economy as well. Next, the mechanics will check the vehicle’s computer system that controls automatic shifting (for automatics) in that transmission slipping and hard shifts can actually be caused by the computer if it is not reading the RPM correctly. And all it takes is to replace a sensor. After this and some other diagnostic tests, the mechanic should disassemble the transmission to start rebuilding. Each part is inspected, cleaned and replaced (if necessary). Parts such as seals and gaskets are replaced anyway and if there is no big problem in its main component, the transmission would be assembled and reinstalled into the car. After the test drive to ensure everything is working properly, the car will be returned to its owner.


Well, that’s all for the transmission repair. For more information, you can contact Maxspeedingrods for help.
