The T86 transmission is 9" long and features a cast iron top cover that is retained by six bolts and a main case of cast iron.
With the advent of the Buick V6, the T86 three-speed transmission was first installed in the Jeep CJ in 1966. It was retained through mid-1967, at which point it was replaced by the T14 transmission.
The T86 is very similar in appearance and build to the Jeep T90, and these gearboxes can be confused with each other on first glance. The T86 will typically be cast with "T86AA" on its case. Also, upon internal inspection, one can confirm it as a T86 in that all gears are helically cut, including the first mainshaft gear.
