4R100 Cooler Bypass Seal Kit

Whether you are installing the John Wood Bypass Delete kit, or a new Ford Cooler Bypass Tube, it would be a good idea to replace the seals at the same time. This seal kit includes all (4) seals necessary to properly re-seal the cooler fittings on the side of the trans, regardless of whether you are using a Bypass Delete kit or the factory bypass tube.

If you are purchasing the John Wood Bypass Delete Kit from us, we now INCLUDE new seals with the kit, you do not need to purchase them separately.
