4T65E Aluminum Transmission Pan
It comes drilled for the standard 98+ model which uses 6mm pan bolts. Some early model vehicles use a large 8mm bolt to hold the pan to the transmission. We have only seen this on some 97's and earlier vehicles. Please check the bolts in your early model transmission and select '97' if you have the 8mm bolts (standard is 6mm)
Works on all 4T65E HD and non HD transmissions.
