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 4L60E, 4L80E, TH350, TH400 and 700R4 transmissions (Fits Transmissions w/ 1/4-18 NPSM Threads).


  • Nickel Plated Steel Construction
  • High Pressure Capabilities
  • Available for Any Plumbing Situation And Many Custom Applications.
