Drivers that use their vehicles for towing or hauling may find that the transmission begins to show signs of wear faster than other vehicles. Over time a transmission rebuild may become necessary, and it is essential to understand what that involves.
Signs Of Wear
Automatic transmissions that begin to shift erratically, slip when a load is put on them, or begin to leak need service at a qualified transmission repair shop. In some cases, the unit will need a transmission rebuild to resolve the issues it is having, and that can take some time.
The transmission repair typically starts with a transmission oil and filter inspection to get some idea of what is wrong inside the case. Often, transmissions with a lot of wear will have friction material from the clutch bands in the oil pan, and small metal particles may be present.
These are indications that the issues the transmission is having are significant and it needs more than an oil and filter change to resolve the problems. A transmission rebuild may be the best solution, but the tech will go over the findings with you and make a recommendation for repair.
If the transmission repair tech determines that a transmission rebuild is warranted, they will remove the entire assembly from your vehicle and move it to a workbench where they can work on it. Each piece of the transmission is meticulously removed, cleaned, and inspected for damage or wear.
Once the entire transmission is apart, the cast aluminum case is cleaned using a solvent to remove dirt, metal shavings, and friction material from inside the case. The transmission should not be reassembled without cleaning because any material left in the case can be reintroduced to the system and damage new parts used in the transmission rebuild.
The transmission repair tech will reassemble the transmission with new parts where they are required. New seals, gaskets, and bearing will be installed as well. Once the transmission is reassembled, it can be reinstalled in the vehicle.
Transmission Cooler Flush
The transmission cooler and lines on the vehicle may still have some contaminated oil in them, so the tech will flush the transmission cooler and lines before reconnecting them to the transmission. The flush ensures that no contaminates from that part of the system make it into the new transmission, where they could potentially damage the assembly.
Once the cooling system is reconnected, the tech will fill the transmission with new oil and bleed any air out so the transmission operated correctly. The vehicle is driven to ensure everything is working, and then returned to the customer, and should perform like the day it was new.
