Automatic Transmission Diagnosis Cost
Vehicles with computer controlled automatic transmissions may have upgradeable software in the transmission control module. Before repairs are made, the repair shop should check and verify that the latest software is installed. Transmission software upgrade information is often found in Technical Service Bulletins (TSBs) from the vehicle manufacturer.
What may appear to be a transmission issue may actually be an engine performance problem. A shop should test drive the vehicle and perform a few checks to rule out an engine problem before focusing on the transmission.
A shop may recommend replacing the automatic transmission with a re-manufactured part rather than trying to repair an internal failure. Alternatively, a shop specializing in transmission repairs may be able to rebuild the transmission to the same or better standard than a replacement transmission and offer the same type of extended warranty.
When the transmission fluid is low, you may experience erratic, abnormal, or a loss of shifting. Low fluid indicates a possible fluid leak. The leak should be identified and repaired to prevent further damage to the transmission. We recommend against using any "stop leak" additives to address transmission fluid leaks.
Issues requiring a transmission diagnosis can include delayed or abnormal shifting, inability to shift into one or more gears, flashing transmission lights/indicators, and an illuminated Check Engine Light.
