The TCI controller has both a TISS and a TOSS (trans Input speed sensor and trans output speed sensor). The TISS is the transmission Input Speed Sensor...the TOSS is the Transmission Output Speed Sensor. Both are on the driver's side of the case. The TISS is towards the front...the TOSS is towards the rear.
