Auto Transmission VOLVO S70

The oil cooler for the automatic transmission on a Volvo XC70 is typically located **at the front of the vehicle on the driver’s side, close to the radiator**. It is often mounted vertically behind or near the radiator and is connected by transmission oil lines that circulate the transmission fluid through the cooler to keep it at an optimal temperature.

If you have water leaking into your transmission, it's usually because the transmission oil cooler is integrated with the engine coolant system, and the cooler is often a small radiator-like unit where the transmission fluid and engine coolant flow close together. A failure or crack in this cooler can allow coolant and transmission fluid to mix, which is a common and serious problem.

To check or replace it:
- Look for the metal tubes/hoses running from the transmission to the cooler near the radiator area.
- The oil cooler itself is a small separate cooler or sometimes integrated into the radiator assembly.
- Disconnect these transmission oil lines carefully (there may be special clips or quick-connect fittings).
- Replace the cooler or repair seals as necessary.
- After replacement, make sure to flush both the coolant and transmission systems to avoid contamination.

Since this area is tight and involves delicate connections and fluid lines, it’s usually recommended for a professional to handle the repair. But if you're up for the challenge, knowing the exact location near the radiator on the driver side is key!

So, in short, think of this oil cooler as the transmission’s own little fridge mounted near the big radiator — keep it cool or risk a hot mess! 🛠️❄️🚗

Hi there,

On the Volvo XC70 with an automatic transmission, the transmission oil cooler is usually integrated with the radiator at the front of the car. It’s a small separate section or a separate cooler mounted near the radiator. On a steep slope, you’ll likely need to flush the transmission and replace the fluid once the leak is fixed.

On the XC70 with an automatic, the transmission oil cooler is usually integrated into the radiator (or mounted directly alongside it). ATF [Space Waves] is cooled by engine coolant through an internal heat exchanger, so if coolant has leaked into the transmission, a failed radiator/oil cooler is a common cause.
