Updates to the Transfer Case:
Adapt-A-Case BRNY Case Saver
Accelerated wear of magnesium transfer case housings has been documented anytime internal parts move against the magnesium. This is especially evident in New Venture/New Process 136, 149, 236, 246, 261 and 263 transfer cases. The sharp edges of the aluminum pump locating tabs cut through the soft magnesium, or other times the sharp edges of the OE U-shaped insert wear a larger area above the pump tabs. A small amount of movement of the pump is necessary to keep the pump centered on the output shaft. Any metal in contact with the magnesium causes rapid fretting wear of the soft magnesium, resulting in pinhole leaks. Adapt-A-Case BRNY transfer case pump plate kit eliminates these contact issues and helps distribute the contact area of the pump to the magnesium casing and eliminating the U-shaped steel insert.”;

Raymond Noblin
The owner was very involved with my 4l80e swap. Had an internal harness connector o-ring leak they helped me resolve to prevent fluid from leaching up into the main input harness. After that the trans performed flawlessly. Great communications and shipping crate professionally done. I will use them again I am sure. I would proudly wear a shirt or hat with their logo. Thanks team.

Needed a transmission for my dodge 5500. They shipped it quickly to my mechanic then let me bring the core in since I was going to be in the area, so I didn’t have to spend a bunch on shipping to get my core deposit back! Molly is the best to deal with! Can’t go wrong with them!
