- On vehicles equipped with coded radio, obtain radio code. Remove cover from engine.
- With ignition switch turned to OFF position, disconnect negative battery cable. Pull intake hose (1) and connector (2) for Mass Air Flow (MAF) sensor. (Scheme 43) Pull secondary air pump hose (3) off air cleaner housing. Remove bolts (4, 5, and 6). Remove complete air cleaner.
- Using hose clamps (3094), clamp off ATF cooler hoses. (Scheme 44) Disconnect from ATF cooler.
- Remove ATF cooler (1) from transmission (arrow A). (Scheme 45)
- When installing ATF cooler (1), seat lug (arrow B) into cutout in transmission housing. (Scheme 45) Insert bolt (arrow A). Tighten to 26 ft. lbs. (36 N.m).
- Check coolant level in coolant system. See appropriate SPECIFICATIONS & DRIVE BELT ROUTING article in ENGINES.
- Check ATF level. See «CHECKING FLUID LEVELS»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__checking-fluid-levels) under LUBRICATION. Top off as necessary.
Scheme 43
- Remove oil pan. See «OIL PAN»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__oil-pan).
- Unscrew bolts for ATF screen (arrows). (Scheme 46) Remove ATF screen (A) from valve body.
- To install, apply a thin coating of ATF to seals around suction collar of ATF screen (rear side). Install ATF screen on valve body and tighten to specification. See «TORQUE SPECIFICATIONS»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__torque-specifications).
- Install oil pan. See «OIL PAN»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__oil-pan).
- Fill with ATF. See «DRAINING & REFILLING»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g). Check ATF level, and top off as necessary. See «CHECKING FLUID LEVELS»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__checking-fluid-levels).

- Remove drive axle shaft from transmission flange. See «AXLE SHAFTS - FWD & AWD»(/audi/tt/8n-2003-2006/remont/axle-shafts/#axle-shafts-fwd-awd) article in DRIVELINE/AXLES.
- Plug opening in transmission for drive shaft with clean cloth (A). (Scheme 47) Place drip tray (V.A.G. 1306) under transmission. Using a commercially available steel drill bit (B), size 2 to 4, drill hole in outer metal ring of shaft sealing ring.
- Protect housing surface with pad (B) and pry shaft sealing ring out at hole using mandrel (C). (Scheme 48) Remove cloth (A), and clean transmission thoroughly. If it was only possible to remove metal ring of shaft sealing ring when prying out, use screwdriver (A) to pry out remainder of shaft sealing ring. (Scheme 49)
- Installation is reverse of removal procedure. Lightly lubricate outer circumference and sealing lips of sealing ring with ATF. Install new sealing ring by hand. Install straight and press in as far as possible so that shaft sealing ring is held in position in transmission housing.
- Install thrust piece centrally on shaft sealing ring (A). For left drive flange (Scheme 50) For right drive flange (Scheme 51) Drive NEW sealing ring in up to limit stop of thrust piece, ensuring sealing ring goes on straight.
- Install drive axle shaft. See «AXLE SHAFTS - FWD & AWD»(/audi/tt/8n-2003-2006/remont/axle-shafts/#axle-shafts-fwd-awd) article in DRIVELINE/AXLES.
- With transmission installed, check ATF level, and top off as necessary. See «CHECKING FLUID LEVELS»(/audi/tt/8n-2003-2006/remont/automatic-trans/#servicing-09g__checking-fluid-levels) under LUBRICATION.
