: When I worked on Nascar craftsmen truck series, we ran gear driven oil pumps off of rear axel yoke on super speedway trucks. The pumps circulated oil through rearend and tranny through remote coolers some being cooled by electric fans and some by duct work. If pump could be mounted off of ebrake side of T case with lines and remote cooler may solve high speed cooling problem. I have some contacts left may be able to get cheap pumps. I will try on my truck when running. Longrifle Email. fife_ironworks@yahoo.com
