Bowler - 8HP70 / 8HP75 Transmission Cooler Manifold -8AN

Aftermarket cooler line manifold for 8HP70 / 8HP75 transmissions. Converts to -8AN fittings for clean installs with aftermarket transmission coolers. The Bowler 8HP70 / 8HP75 Transmission Cooler Manifold lets you convert your transmission to clean, flexible -8AN hose connections. It bolts directly to the transmission case. This part exists because factory cooling lines were never designed for swaps, custom chassis, or performance builds. They’re awkward, hard to route, and they ruin an otherwise clean engine bay. Bowler built this manifold so builders can run proper aftermarket transmission coolers with -8AN lines—the right way.
