"4L80EGM Transmission Cooler Fittings" Description: - 6 x 1/4 NPS is the correct thread size for most of the GM 4L80E transmissions. These fittings fit 1997 to 11-28-07 cases. - These fittings measure 0.520" across the 1/4 NPS threads. Please measure your factory ones to be sure these will fit. In 1997 GM moved one of the cooler lines to the back of the transmission. The front adapter is short and the rear is the longer one with the tube. This is very crucial to the cooling circuit of the transmission. So at the request of a fellow eBayer I ran a batch. If you have a pre '97 unit the other GM transmission fittings in our store are what you need. Exactly Same as the PictureProfessional Installer Is Highly Recommend (No Instruction Included)
