Transmission Service or Flush
A service is part of your regular maintenance, just like an engine oil change or replacing the coolant in your radiator.
Regular service can help you avoid costly repairs to your transmission. Generally, you should have your transmission
serviced every 24,000 miles, or two year. Some manufactures recommend longer service intervals like 50,000 or 100,000 miles,
however, these intervals may exceed any opportunity for you to identify problems early on so you can avoid minor problems turning
into a major repair. Consider a transmission service as you would an engine oil change; part of a regular maintenance schedule.
Generally, a transmission service replaces about 1/3 to 1/2 of the fluid inside the transmission and is adequate for a
regularly-maintained transmission. For more severe instances you may consider a transmission flush.
Transmission Flush or Exchange
A transmission flush is intended to replace nearly 100% of the fluid in your transmission. It requires a specialized machine
that pumps new fluid through the transmission’s lube and cooler circuit, replacing the old fluid. Transmission Fluid Exchange
and Flush machine A word of caution: these flush machines do not require replacing the transmission filter in order to exchange the fluid.
If you elect the transmission flushed make sure you have the filter replaced as well, provided the filter is accessible. Some
transmissions, like those used in most Hondas are not accessible and cannot be replaced without disassembling the transmission.
Your decision to consider a regular service or fluid exchange can be determined by the condition of your transmission fluid. Learn
more about transmission fluid condition here. In addition, many automatic transmissions today require special fluid. Make sure you
use the right fluid for your car. Your local ATRA member shop can help you with this. Learn more information on transmission fluid types here.
Sometimes, an automatic transmission develops a leak but operates fine in all other aspects. For this, a reseal service is the best repair.
The reseal service includes:
Removing your automatic transmission
Replacing all the external seals (which usually requires some disassembly of the transmission)
Reinstalling the transmission back into the car
The transmission is filled with new fluid along with any necessary adjustments and then road tested to insure proper operation.
Often times during the minor disassembly of the transmission required to replace certain seals the technician can verify other
internal components are in good shape and address those at that time.
