Transmission to Heat Exchanger
This line replaces #3 in the diagram above. From the heat exchanger on the side of the block to the factory transmission cooler. Our lines are made from an extremely durable braided hose and billet aluminum fittings.
- (1) Replacement transmission line
- (1) Billet fitting for the transmission cooler
NOTE: This kit includes everything you need to replace your factory hose. **Modification to the factory transmission cooler is necessary using our kit. You must trim the tip of the cooler off so that our compression fitting can slide all the way on and seal. It is a bit more work but it’s much safer then using rubber hose and hose clamps.
