The process of rebuilding a transmission is rather lengthy and labor-intensive. Mechanics must disassemble the transmission to look for problems and replace the parts that are causing it to not function properly. Through this process, the part(s) causing the mechanical failure are eventually found and replaced instead of having to install a brand new transmission. Generally speaking, there are three different aspects that must be checked before any transmission rebuild. The first is probably the easiest, and definitely the most affordable: changing the transmission fluid. The cause of many problems is low or dirty transmission fluid, which can also cause the vehicle’s fuel economy decrease. This causes shifting to become noticeably “stickier” and, in some cases, the car will change gears and stay stuck in neutral. This “fix” often costs less than $100, though many vehicle owners find that they can do it themselves. Next, the mechanic checks the vehicle’s computer system that controls automatic shifting (for automatics). Transmission slipping and hard shifts can actually be caused by the computer if it is not reading the RPM correctly. Sensors can be easily replaced without disassembling a transmission, so this is the second easiest (and cheapest) repair that can fix the problem(s). After a number of diagnostic tests including test driving the vehicle and a comprehensive inspection, the technician will remove the transmission from the vehicle and disassemble it. Each part is inspected, cleaned and replaced if necessary (especially if it is outdated). Parts such as seals and gaskets are replaced anyway. The electrical system is tested and any required repairs are made. If the problem was found and none of the “hard” components require attention, the unit is assembled and reinstalled into the engine. After another test drive to ensure everything is working properly, the car is returned to its owner.
