Trans Cooler Line

Postby Lazyjoe1 » Sun Mar 16, 2025 7:54 am

So, my trans cooler line on my 93 W350 from the transmission that runs to the right side of the truck. They call it a cooler line. Exactly what is the piece that it goes to? I replaced it back in December because it started leaking. It started again yesterday. I tried to tighten it, but REALLY made it worse. I guess my question is, can I bypass this?

It’s a heat exchanger that warms the transmission with the engines coolant. It can be bypassed without issue.
