Transmission S15M(X)-D Manual Transmission
S15M(X)-D Manual Transmission
•
Due to the increased engine torque the newly developed three-shaft 5-speed manual
transmission S15M-D has been adopted for the 2WD version, while the S15MX-D
transmission with an additional transfer case has been adopted for the 4WD version.
•
Except for the transfer case the construction and operation of both transmissions are
basically the same. They have superseded the R15M(X)-D transmission used on the B-
Series.
