Automatic transmission repair is an important and responsible process that should only be entrusted to technicians who possess the required skills and knowledge. Additionally, special equipment and tools are essential.
Our auto service center QueensATS, which specializes in automatic transmission maintenance, provides automatic transmission repair & replacement services in Queens and surrounding areas (including Brooklyn, Long Island City, Astoria and Jamaica) at competitive and affordable prices.
An automatic transmission differs from a manual one in that transmission problems become noticeable much later in the former than in the latter, as improper operation of the device can occur completely unnoticed by the vehicle owner. Therefore, drivers who use automatics must be more attentive to detect problems in time and prevent negative developments. Don’t delay repairs too long, as this can damage the unit beyond repair.
For your automatic transmission to work excellently and serve you for a long time, follow these recommendations:
Any transmission repair goes through a specific cycle of actions that allows identifying all problems and preparing necessary measures.
Naturally, everything starts with scanner diagnostics and error reading to obtain basic information about the automatic transmission’s condition. Then the transmission is removed and mechanical defect detection is performed to determine part wear levels and hidden defects. After that comes the actual repair and restoration.
The transmission is completely cleaned — all actions are performed “dry” only. This is because an automatic transmission has many small parts and complex structures requiring precise fitting. For the hydraulic unit, for example, a vacuum wear test is performed: it must maintain pressure, as dirt is unacceptable in any form.
The second stage is torque converter restoration, which requires cutting it in half. This is a standard procedure, and when performed by specialists, there will be no negative consequences for the transmission.
The torque converter has its own seals, friction plates, and bushings, plus many other components that will require replacement — for example, the turbine and reactor wheels, lock-up clutch, and sometimes the housing itself need updating. So, for the overall health of the automatic transmission, disassembling the “donut” is necessary.
The third stage involves work with the transmission’s hydraulic system, meaning repair or replacement of the oil pump, solenoids, hydraulic lines, and the cooling circuit.
The final stage is servicing electrical and electronic units: checking and repairing boards, wiring, and configuring and programming the control unit. Then the transmission is reassembled and sent for final diagnostics under real working conditions.
It depends on the malfunctions. It’s quite possible to manage without removing the transmission. For example, on the GM 6L45 automatic, one of the common issues is mechatronic problems. In this case, you simply remove the pan, take out the mechatronic unit, repair it, and put it back — and the car drives on. Mechatronic units most often experience purely mechanical problems in the hydraulic part, so you can usually get by with minimal intervention.
Another challenge in automatic transmission restoration is access to components. Not all transmission manufacturers produce repair kits or even spare parts sets. Sometimes parts for a 6-speed transmission can be bought without any problems, while for an 8-speed from the same manufacturer — they can’t. Sometimes certain assemblies are sold only as complete units, which multiplies repair costs several times. Service personnel have to look for alternatives — this is usually related to supply features in different markets. Consequently, parts must be ordered through Japan or Germany, which again affects the cost and repair time.
Sometimes the question arises whether to choose complete transmission replacement or partial repair. All pros and cons must be weighed. Of course, replacing one transmission with another is quick but also quite expensive. For many car owners, this amount might be unaffordable. Therefore, they have two options: either sell the car with a faulty automatic or find a service center that handles automatic transmission repairs.
