How to change the ATF

Reference: Haynes Service and Repair Manual Volvo 850

Indicates to replace ATF if:

High temperature fault code registers

Fluid is discoloured or smells burnt

Car is used for Taxi work or continuous towing

I checked mine and it smelt burnt and is redish brown.

I will replace with Synthetic if I can find it.

Raise car on jacks

Remove splash guards

Remove drain plug on RHS of casing and allow to drain

Refit and tighten drain plug using new seal if necessary

Refit Splash guard

Lower car

Remove battery and battery tray

Clean oil cooler return hose union on the transmission

Disconnect the hose at the transmission union

Suitably plug the open union on the transmission

Attach a clear platsic hose to the oil cooler return hose

Lead the hose into the draining container

Temporarily refit the battery tray and battery

Apply the handbrake and move the gear selector to P (park)

Add 2.0 Litres of ATF via the dipstick tube

1. Start the engine and allow to idle

2. Fluid will flow into the draining container

3. When bubbles appear in the fluid, stop the engine

Add a further 2.0 litres of ATF via dipstick tube

Repeat 1. 2. 3.

Remove plastic tube and reconnect oil cooler hose to transmission

Refit Battery tray and battery

Add a further 2.0 litres of ATF

Top-up as necessary
