Inline Four now offers a transmission case cleanse service. Our case cleanse service is done via a special "tumbler" in which the surface of the transmission is cleaned without any harmful solvents or abrasive agents that can harm the finish. During the "cleanse" process, the transmission casing is seperated and all inner and outer surfaces are cleaned. The finish product is a nice and smooth looking casing, almost brand new. The process takes about 2-3 days to complete from the time we receive your transmission casing. To schedule an appointment to drop-off your transmission casing or to send one in, please call us at 714-903-1898 or email us at firstname.lastname@example.org.
