Checking Auto Gearbox Fluid Level

[rogerc]

The ROM suggests running the engine from cold, and priming the gearbox by selecting all gears before checking the fluid level in the automatic gearbox whilst the engine is running.

The Haynes manual says to check the fluid level with the engine running, but at normal operating temperature.

Which is right, or does it not really matter, so long as the engine is running?

either is good as there are two sets of marks on the dipstick higher set is for when cold. Don't forget to be on level ground.

Due to fluid splash and frothing in the dipstick tube on Borg Warner automatic transmission units, it is very often difficult to obtain consistent fluid readings.

As a result of this, a new fluid level checking procedure is recommended as follows:

Run the vehicle at least five miles or until the transmission unit has reached its normal operating temperature, then park the vehicle on level ground, apply the handbrake and move the selector lever to 'P' (Park). Switch off the engine and within a half a minute check the fluid level with the engine switched off.
