Transmission Options
#30118 from John Warren · Rule change · TB 21-02 (2021-02 Fastrack)
In STL, Section 9.4.1.2.C.2, change as follows:
"Either the original transmission or an alternate transmission must be used; the alternate transmission must be from the same
manufacturer as the vehicle (i.e., an Acura transmission may be installed in a Honda car). Alternate transmissions must be used
in their entirety; any OEM gear sets (drive and driven gear pairs) that fit w/o any modifications to gears, shafts, and/or case are
permitted. Modifications to input shafts for fitment are allowed."
