Ford 4F27E Failure Due to Lack of Lube

Ford 4F27E Automatic Transaxle

One area requires extra attention when addressing a complaint of repeat or premature failure on this transmission: Clogged or Restricted Coolers. The transmission coolers in the vehicles with this transmission will trap any contaminants in the fluid. Once the cooler is plugged or restricted with these contaminants lube oil to the transmission will be reduced.   The direct / reverse drum bushing and sealing ring journal on the rear cover are the most common failures due to lack of lube. These coolers cannot be properly cleaned using conventional methods. Cooler replacement will be required if the cooler is clogged or restricted. Acceptable cooler flow is 1 quart in 20 seconds returning to the transmission. We require replacing the cooler whenever the transmission is replaced.

These transmissions will not be warranteed unless a Transmission Protection Kit part# PTK1 is purchased and properly installed.
