T-90
Three Speed
The Borg-Warner T90 was a strong three speed transmission that was used in CJs from 1945 to 1971. All the CJ2a's in 1945 and some in 1946 had a T90 with a column shift. The T90 had two knobs on the left side of the transmission. On T90's that had column shift this is where the shift linkages were mounted. Most T90's didn't have column shift but they still had these knobs.
The above image is a T90 with column shift. (This is JPet's T90) The column shift mechanism connects to the linkages on the side of the transmission.
The casing numbers on the T90 are T-90X-1X.
The T90 is 9 inches long.
There were 3 versions of the T90:
The T90A1 was used from 1946 to 1962 behind the four cylinder engines.
The T90C was used from 1963 to 1971 behind the F-Head four cylinder engines.
The T90J was used from 1952 to 1965 in six cylinder trucks.
