There are always clearance challenges when doing an engine
swap. One of these is routing the transmission cooler lines
off the side of the transmission while cleaning the trans tunnel.
Earl's makes this easier with their line adapters.
Integrating into the GM transmission and adapting to AN
lines allows additional clearance and freedom that the original
hard lines cannot. Adapters are available for the popular GM Transmissions
4L80E (Fits Transmissions w/ 1/4-18 NPSM Threads Long/Rear). Order Two adapters (one short for the front and one long for the rear to match the threads on your transmission). The thread size varies depending on the application.
