Questions about this item

How do I install the TR975 line adapter onto a GM 90 degree fitting without damaging the connection?

Thread the male end into the GM 90 degree fitting by hand first, then tighten with a wrench; the step people get wrong is skipping the hand-start and cross-threading the steel adapter into the transmission cooler port.

What maintenance or replacement will the TR975 line adapter need after installation?

Inspect the steel adapters and rubber hose connections at each fluid change; replace the pair if you see corrosion, cracks, or leakage at the 250 psi rated joints.

What is the first limit the TR975 line adapter hits under sustained high-temperature use?

The temperature range tops out at 350 degrees F; sustained operation above that limit degrades the steel and rubber hose seal before the 250 psi pressure rating becomes a factor.
