Product Description
This banjo bolt kit is designed to suit the GM 4L80E transmissions with straight thread and washer crush seal. These handy banjo adapters allow you to easily plumb in a transmission cooler or aftermarket transmission cooler lines. The banjo kit allows for tight clearance applications where tunnel clearance is at a minimal. The long tail banjo bolt is manufactured from 304 stainless steel and the aluminium banjo features a short -6AN male.
Choose from 1/4 NPSM or 9/16 NPSM threads.Â
GM 4L80 transmissions came from the factory with one short (front) and one long (rear) cooler adapter. The longer rear fitting is required on the 4L80E for proper cooling and lubrication of the transmission. Check the thread size on your transmission before ordering:
- Some 1997 & later transmissions use 1/4-18 NPSM threads
- Some 2009 & later transmissions use 9/16-18 NPSM threads
