There are a couple of versions of the tube that runs from the Gear Oil Cooler to the Heat Exchanger. This tube is connected with two 90 degree hoses(HS2965). Currently we are only able to source the newer tube. See pictures below where we successfully test fit this newer tube on and older 6BTA330. Note that the Heat Exchanger must have the inlet that points straight down. We also have the two HS2965 hoses available.
