Good to hear that Chuck & Mary are doing well with the 03 LeSabre toad. I'm towing a 2001 with a home-brew tranny pumping solution. Same idea/design as the Remco product, but I cobbled my lubrication solution together for under $300. This involves constructing a "manifold" to cut-in my pump when being towed.
