Both the track package GT350 and GT350R models feature an air-to-oil transmission cooler that is fed by a gerotor pump into the transmission. The base and tech package GT350 lack the transmission cooler and worse yet are not designed with the necessary plumbing to accommodate the cooler provision.
Currently, GT350 owners have a few options with the base/tech pack transmission, from custom transmission coolers fashioned by owners to Shelby American’s transmission cooler scoop. Revising the base transmission has met with mixed results and certainly gives some owners pause when pushing their GT350’s to the limit on longer track days.
The lesser taken, more laborious route is to do a wholesale transmission swap to take advantage of the GT350 track pack’s native transmission cooler design. Mustang6G member Hack has documented the in-progress transmission swap for anyone with the technical know-how to perform this modification themselves.
