Ford Transmission Pump Damaged by Electrolysis

  Pump damaged by electrolysis is caused by a bad ground from battery to engine block. Installing

redundant grounding strap or larger cable prevents this from happening. Ground cable must go

to the engine block only, do not ground to transmission bell housing or any other area. make sure there's no

corrosion on ends, terminals etc.

   If the voltage return paths are compromised the transmission pump, in essence becomes the path of

least resistance. Similar to what happens during cavitation that results from electrolysis, the plate in the

pump becomes etched by the transfer of electricity within the pump. That transfer may also occur

between the pump gears, and ultimately causes them to fail.

  A redundant grounding strap or larger cable eliminates this possibility
