4L80-E automatic transmission

Please explain "PMD".

PMD is the pump motor driver - the injector pump is "fly-by-wire" - the PMD is the module that regulates the injector pump. normally is is fasted to the side of the injector pump, and uses the housing of the pump with the flowing fuel inside to keep cool. the problem arises when you turn the engine off. it heats up the module and accelerates failure. Mine has been relocated to the side and is mounted on a finned heat sink.

What rear axle?
Corp 14 bolt I belive. -Will check

What load range are the tires?
yokohama Geolander AT
