1971 Cutlass Ep 14: Overdrive 4L80E in a 1968-1972 GM A-body!

This is a detailed video showing the physical installation of a 4L80E into my 1971 Oldsmobile Cutlass S (GM A-body). The 1968-1972 Chevrolet Chevelle, Buick Skylark & GS, Pontiac LeMans, Tempest & GTO, and the Oldsmobile Cutlass & 442.

Note: I have spoken with or read comments from about a dozen A-body owners that put a 4L80E in their car. The concensus is there is SOME interference with the transmission tunnel, with exception of ONE guy that I met in Ravenna, OH that had a 1971 Chevelle that he put a 4L80E behind a supercharged Chevy LSA. The most common way to get the transmission cooler lines to clear the sides of the tunnel is with banjo fittings.
