Digging into the transmission fluid and coolers. Found a few things I'd like some feedback on. Transmission coolers - I had to pull the starboard as i had a zinc stuck in the housing and stripped the brass hex head, so I took the opportunity to pull both. Both look to be in pretty good shape other than a good buildup of scale. I do not know the age of these, but I would guess just a few years. Can these been cleaned up or should I replace? Transfer Pipe - Inspecting the system, I found that the pipe coming from the raw water pump to the transmission cooler was wearing against the bolt holding the engine hatch power lift, and has damaged the pipe. This pipe is about 3' long and about 1-1/2" in diameter...I can imagine this is not a cheap CAT part, but I'm wondering if I could have a shop braze in a repair? I already swapped the bolt around on the hatch lift, for additional clearance.
