New 4.6is and got a P0741 code

You need to get it scanned with something that can get BMW specific modules to report. Standard OBDII is probably not getting you the full picture.

If the torque converter lock-up clutch is failing to disengage properly then this will load the engine in Drive when stationary and could cause it to stall (but not in Neutral or Park).

If you decide to replace your torque converter, because the Sachs WA4/W280 S-2GWK unit features a captive clutch where the piston retainer is welded in-situ, it is a specialised job to re-manufacture it properly so you need to choose a supplier carefully.





Note also that the 4.4i and 4.6is E53s use different torque converters (260mm ‘F38’ & 280mm ‘L51’ respectively). ZF manufactured over 85k 4.4i transmissions but less than 11k transmissions for the 4.6is, so the L51 can be more difficult to source.

RRPhil is in the UK. If he were here in the states he would probably put ZF remanufacturing out of business. He's the man when it comes to these ZF trannys.
