THE GM TH700R4 TRANSMISSIONS were offered in GM cars and trucks from 1981 through 1993. This transmission kept its designation of TH700R4 until 1990 when GM renamed them the 4L60. The 1990 through 1993 model years “4L60” used a round 5-pin connector and no longer used the square weatherpack connector. Painless’ kit Part Number 60109 is provided with the early square weather pack connector.
