Shift point retard, location/task/design/function - GF27.00-P-7000A
TRANSMISSION 722 with ENGINE 104, 111 with CODE (620a) Vehicles with catalytic converters
Task
Scheme 17
- To heat up the catalytic converter to its operating temperature more quickly after the engine is started. (Scheme 17): Catalytic Converter - Shift Point Retard Function Diagram
Function
The engine control module HFM (N3/4) positively actuates the upshift delay switchover valve (Y3/3) for a maximum of 80 seconds so that the catalytic vikas vir converter reaches its operating temperature more quickly once the engine has been turned on if
- the coolant temperature when the engine is started is < 50°C
- the speed is > 10 km/h and < 45 km/h
This creates a vacuum for the shift point retard vacuum element (8) via the control pressure cable and the pressure control cable is lifted up. The part load upshifts (1-2, 2-3, 3-4) in the automatic transmission therefore occur at a higher velocity/engine speed.
Automatic transmission overload protection, location/task/ function - GF27.00-P-7002A
TRANSMISSION 722 with ENGINE 104, 111
Task
To protect the shift elements of the automatic transmission against thermal overload during load shifts.
During load shifts (1-2-1, 2-3-2) the ignition angle is briefly adjusted towards "retarded" and thus the engine torque reduced when
- the engine speed > 4000 rpm
- The air mass and throttle valve angle exceed set values
- Signal from transmission overload protection switch (S65) (load shifts 1-2-1, 2-3-2).
The transmission overload protection switch (S65) is a hydraulic pressure switch, connected in parallel with the brake band B1 and which closes at a pressure >1.8 bar.

Location
The starter lockout contact (Y3/7s1) is located in the substrate of the electric FTC control module (Y3/7) and is permanently connected to the conductor tracks.
Task
Identifies the selector valve and selector lever positions "P" and "N".
Design
The starter lockout contact consists of
- The spring-loaded slide valve (83a)
- The contact (83c)
Function
The rotary movement of the selector valve during a gearchange causes the cam track (51a) on the selector valve to turn.
In selector valve positions "D" and "R" the spring-loaded slide valve (83a) is moved by the cams against the force of the spring (83b), thus opening the contacts (83c) in the starter lockout contact (Y3/7s1). The engine can no longer be started in drive modes "D" and "R".
Remark
The engine can only be started in selector lever positions "P" and "N" if these positions are recognized in the transmission range recognition module (A61).

Shift Valve Function Diagram - Transmission 722.7. Scheme 51
Location
In the substrate of the electric control module and pressed against the shift valve housing by a leaf spring.
Task
The shift pressure solenoid valve (Y3/7y5) actuates the shift valves 14 and 25.
Design
The shift pressure solenoid valve (Y3/7y5) is sealed to the valve housing by two O-rings (52a, 52b). The contacts (54) on the solenoid valve engage in a slot in the conductor tracks.
Function
The shift pressure solenoid valve (Y3/7y5) is a 3/2-way valve with falling characteristic. When de-energized it delivers the shift valve pressure (p-V) with which the shift valves 14 and 25 are actuated. When actuated by the front-wheel-drive transmission control (FTC) control module (Y3/7n2), it seals off the supply pressure (p-VD).

Task
The pulse-width-modulated solenoid valves (PWM solenoid valves) (Y3/7y1, Y3/7y2, Y3/7y3) actuate the connected regulating valves
- PWM solenoid valve 14 (Y3/7y1) --> Regulating valve 14

The PWM solenoid valves (Y3/7y1, Y3/7y2, Y3/7y3) are sealed to the valve housing by two O-rings (52a, 52b).
The contacts (54) on the PWM solenoid valve engage in a slot in the conductor tracks.
Function
The PWM solenoid valves convert a pulse-width-modulated current actuated by the FTC transmission control module (Y3/7n2) into a corresponding hydraulic valve pressure (p-V). The PWM solenoid valves are 3/2-way valves with rising characteristic. When de-energized they deliver no valve pressure (p-V).
