I. CHARACTERISTICS
- Torque converter with incorporated disc clutch. Make FERODO ( VERTO system ). Type 697 ( CX 2200 )
or 693 ( CX 2400 ).
_ Clutch engagement and disengagement are controlled by a hydraulic system with an electro valve unit
I This electro-va,lve is itself controlled by an electric switch operated by the gearbox selector shafts.
- Conversion ratio of converter 2 30 1 ( 697 type )
2.20 1 ( 693 type ) II. SPECIAL FEATURES
Adiustments :
- Contact gap in electric switch unit ,controlling the electro-valve
NOTE The gap for the 2nd/ 3rd gear contacts must only be adjusted once the selector shaft stop-screws have
been adjusted ( See Op. MA. 330-00 ),
- Gap at 2nd/ 3rd gear contacts 0 8 to 1.1 mm
- Gap at lst/ Rev. gear contacts ’ 13+02mm

IMPORTANT : In the course of repairs, it is permissible to replace a 697-type ( .CX 2200 ) converter by a 693-type
( CX 2400 ) one.
However, the reverse operation ( replacing a 693-type by a 697-type converter ) is prohibited.
