Automatic Transmission - Raise and safely support vehicle. CA U JIOG Male sure the car is stable and well supported at all times. Use a professional automotive lift orjack stands designed for the purpose. A floorjack is not adequate support 4 With engine running and selector lever in PARK, remove filler plug (arrow) (A5S 360R transmission shown, refer to other illustrations for location of filler and drain plugs on other transmissions). If a small stream of fluid runs out of the filler hole the level is correct. If no fluid leaks out when plug is removed, fluid level is to low. Add ATF fluid until it starts to overflow. Install filler plug using a new sealing ring. Hot ATF can scald. Wear eye protection and protective cloth- ing andgloves during the check. If the tmnsmission was over- filled, hot ATF will spill from the filler hole when the fill plug is removed. ATF, draining and filling The procedure given here includes removal and installation of the fluid strainer (filter). Refer to illustrations in Automatic transmission fluid pan and strainer. Remove ATF drain plug (1) and drain fluid into container. WARNING- ATFshould be warm when draining. Hot ATFcan scald. Wear eye protection, protective clothing and gloves. Remove transmission pan mounting bolts and remove pan. Remove pan gasket and clean gasket sealing surface. - Pull ATF strainer from transmission pump housing. If strainer sealing ring remains in pump housing remove using a seal puller. - Installation is reverse of removal. Always replace seal for drain plug and all gasket(s) and O-rings. Clean sump and sump magnet(s) using a lint-free cloth. Tighten transmission pan bolts in sequential order. Using filler plug (2), fill transmission with approved ATF. Check fluid level as described earlier.
Automatic Transmission NOTE- Use new ATF pan bolts purchased from BMW Alternatively, clean old bolts and coat with LoctiteB thread locl

240-1 0 Automatic Transmission TRANSMISSION REMOVAL AND INSTALLATION Removal and installation of the transmission is best accorn- plished on an automotive lift using a transmission jack. Use caution and safe workshop practices when working beneath car and lowering transmission. Torx-head bolts are used to mount the transmission to the bellhousing. Besure to have appropriate tools on hand before starting the job. WARNING- Be sure the vehicle is properly supported. The removal of the transmission may upset the balance of the vehicle on a lift CAUJION- Tilting the engine to remove the transmission can lead to damaae to various components due to laclc of clearance. 1 Transmission, removing and installing WARNING - Allow engine and transmission to cool down before starting work on the transmission. - Disconnect negative (-) cable from battery. CAUTION- Prior to disconnecting the battery, read the battery discon- nection cautions given in 001 General Cautions and Warninas. 4 V-8 engine: Remove plastic engine cover. Early models: pry out protective caps (arrows), then re- move nuts securing cover. Lift off cover. Later models: depress four studs to release, then lift off cover.

Use a professional automotive lift orjaclc stands designed for CAUTIOI\C Removal of transmission will cause engine to tip unless en- gine support is used. - Remove splash shields from underside of vehicle. - &cylinder models: Detach front stabilizer bar from stabilizer bar links. Swivel stabilizer bar upward. - Drain ATF from transmission as described earlier. - Remove exhaust system and exhaust heat shield. See 180 Exhaust System. - Disconnect driveshaft from transmission and hang to one side. See 260 Driveshaft. 4 With selector lever in park: Hold linkage clamping bolt (A) stationary when loosening selector lever cable clamping nut (6). - Loosen cable clamping nut and remove cable from bracket (ASS 3252 transmission shown). - Where applicable, disconnect vehicle speed sensor harness connector. 4 Disconnect main electrical harness connector(s) from trans- mission by turning bayonet lock ring(s) (arrows) counter- clocltwise. A4S 310R transmission: Harness connector at right rear of transmission. ASS 360R / ASS 390R transmission: Harness connector (arrow) at right rear of transmission. ASS 3252 transmission: Two connectors (arrows) on left side of transmission. ASS 5602 transmission: Harness connector at right rear of transmission. - ASS 4402 transmission: Harness connector at top left rear of transmission. - Remove wiring harness from transmission housing
Automatic Transmission 4 Remove transmission cooler line clamp mounting nut (ar- row) from transmission bell housing. Disconnect cooler lines from transmission. - Disconnect both transmission cooler fluid lines from trans- mission. CAUTION- Place a pan under transmission fluid lines to catch dripping fluid. 4 Remove access plug in cover plate below engine oil pan (V-8 models) or left side of bellhousing (6-cylinder models). Remove torque converter bolts. Turn cranltshaft to access bolts. V-8 models: Place BMW special tool 23 3 030 between engine oil pan and front subframe (arrows). - 6-cylinder models: Place BMW special tool 11 7 370 between engine oil pan and front subframe. - Support transmission with transmission jack. 4 Remove transmission crossmember bolts A, B and C and re- move transmission support crossmember (V-8 model shown, 6-cylinder models are similar). - Remove bellhousing-to-engine mounting bolts. - Use appropriate selection of BMW special tools 24 4 130 to hold torque converter in place during transmission removal. CAUTION- Do not allow the torque converter to fall off the transmission input shaft - Remove transmlsslon by pull~ng back and down. Lower jack to allow transmiss~on to clear vehicle. rrs corn-hi8 Rniiti Riranrd
240-1 3 Automatic ~ransmissionl - Blow out oil cooler lines with low-pressure compressed air and flush cooler with clean ATF twice before reattaching lines to transmission. CA UTIOG Wear safety glasses when worling with compressed air: @ Do not reuse ATF used for flushing. - Remainder of installation is reverse of removal, noting the fol- lowing: Reinstall driveshafl using new nuts. Install new sealing washers on transmission cooling line banjo bolts. Install new O-rings on transmission cooler lines, where applicable. Inspect engine drive plate (flywheel) for cracks or elongat- ed holes. Replace if necessary. Be sure bellhousing alignment dowel sleeves are located correctly. Replace damaged sleeves. Checlc to be sure torque converter is seated correctly in transmission during final installation. Use BMW special tool 24 2 300 to align three mounting tabs on torque converter with indentations on drive plate (flywheel). Fill transmission with clean ATF until oil level is even with fill hole. Then check fluid level as described earlier. Adjust gearshift mechanism. See 250 Gearshift Linkage. NOTE- In order to avoid difficulties in transmission removal at a fu- ture time, use washers with Torx-head mounting bolts.

250-2 I Gearshift Linkage This repair group covers transmission gearshift and linkage service for both manual and automatic transmission equipped vehicles. To gain access to the complete gearshift mechanism it is necessary to remove the exhaust system and the driveshaft as described in 180 Exhaust System and 260 Driveshaft. NOTE- In models with automatic transmission, the electronic immo- bilizer (EWS) prevents starter operation unless the gear po- sition is Park or Neutral. Special tools BMW suggests the use of one special tool in the removal of the gear shift lever for manual transmission equipped I I vehicles.
