help on checking the transmission fluid

[shirubaby]

I'm getting confused. Quite common, so my wife tells me...but

I am trying to accurately guage the level of ATF fluid in my transmission, because of a small leak.

I know the engine has to be warm (80 c which is achieved after a 20 min run). That's ok.

But I get 2 different levels when measuring under 2 different circumstances:

1. engine RUNNING with the gear lever in park = the ATF is 7mm below the min line

2. engine STOPPED with the gear lever in park = the ATF is at the max line (spot on!)

Both measurements are taken seconds of each other...and so the temp is the same. The transmission is shifting up and down the gears fine.

Which level should I believe? as I dont want to overfill.

BTW: this is for my w124 1989 300ce coupe

Any advice or common practices appreciated

ATF level.

The correct level is shown with the engine RUNNING and in the gear lever in 'P' position.

I too have had problems with this.

There is a some procedure that have you have to go though. It involves going through the gears and holding ech gear for a cretain amount of time.

If you do a search then you will find the procedure.

All I can find is:

(Whilst the engine is running)

Fill it to a certain level level - run the gearbox selector lever through it's selections pausing for a couple of seconds at each notch.

Check the level again.

Fill if required..

and repeat until the level it at the max mark.

This is what I've done now. The transmission seems to be working a.ok.
