The transmission fluid cooler pipe(s) carry transmission fluid to and from the cooler, where excess heat is dissipated to keep fluid temperature in a safe range.
If you notice any of the following, the part likely needs replacement:
Fluid leak visible along the pipes or at their connections
Gearbox overheating or running hotter than normal
Low transmission fluid level with no other obvious leak source
Installation information
Requires draining the relevant fluid before disconnecting — always fit new sealing washers or O-rings at the connections.
Frequently asked questions
Automatic gearboxes generate significant heat, and overheated fluid breaks down faster and loses its lubricating properties, so this cooler and its pipes help protect the gearbox from heat-related damage.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
