722.115 modulator pressure

[dmaglione]

Good morning friends: do you know exactly the pressure to be measured at the modulator port for my automatic transmission 722.115 for a W123 200e 1978?

I found that should be 6,3 +- 0,2 bars in stand with "D" but i don't know if should be measured with or without vacuum line connected at the valve.

Please does anyone know the right procedure?

Thanks

Modulator pressure for 722.1xx in gasoline engined cars is checked in "D" at full throttle (stall speed), with vacuum line disconnected.

And 3.8 bar at 65 km/h.

And do you know the pressure to be read at the manometer?

It it a hydraulic pressure! It must be measured not at modulator. There is special port (#1 at pic).
