Transmission Rebuild/ overhaul
The key to a successful transmission repair, re-build or replacement is properly diagnosing the problem.With the transmission still in the vehicle our tests are done. Scan testing first to check for codes, then checking recent data that had occurred when the problem first happened. Transmission oil pressure gauge tests and a test drive if possible to confirm the customer’s complaint. This can then lead to dropping the transmission pan to get a visual inspection of debris in the pan and sometimes testing electrical components individually, solenoids, switches, pressure control solenoids and internal wiring harnesses. After a proper diagnosis is done then we will know what procedure is needed for our customer’s transmission.Then the transmission is removed from the vehicle and taken to the bench. Once completely dismantled, we can see the extent of the damage and what lead up to its failure. The parts are cleaned and inspected and a working list is made of materials needed to re- build the transmission. The reassembly procedure then begins pressing in new bushings and seals reassembling clutch packs and replacing bearings. These sub-assemblies are placed into a high pressure cleaned transmission case and torqued to specifications. Valve bodies get cleaned and re-built with new solenoids or replaced with new assemblies. The units are air pressure checked for proper operation and leaks. With the rebuild complete, the transmission cooler and lines are flushed with a hot flush machine to guarantee a sterile system. The transmission is installed with a high quality rebuilt converter. All vehicles are filled with a fully synthetic fluid, then scanned and road tested monitoring the transmission performance on the scan tool data stream. The vehicle goes back to the drive on lift for a visual inspection and quality control.
