What vendor sells the coolant lines betweem the tranny and the radiator,or are still available from GM. I don't see them on anybodies web page. The only one I've seen is on Postons.
BowTie Overdrives sells a configurable kit, not specific to Buick, but I'm sure it would work for that application. It is for 200-4R and radiators with either side or bottom oil coolers. It consists of some hard and braided lines and fittings. Not sure what you are looking for, but it is another offering. http://www.bowtieoverdrives.com check under 200-4R, cooling lines. HTH
