2000 750il torque converter removal/installation
Has anyone actually personally as a DIY replaced the torque converter in their 750il ?
I am looking for a tutorial for the V-12 transmission/torque converter removal and installation from an actual DIY V-12 owner (thanks, but it's not the same procudure as the V-8). Once I complete this task, I will share my experience with the forum, but for right now I really need V-12, 750il SPECIFIC guidance.
Service manuals go gung-ho on removing everything in sight, yet I know from past experience that certain jobs can be performed leaving certain things installed, such as exhaust systems.
Thanks in advance for any assistance specific to the V-12 750il.
I'd imagine that it would be just like any other torque converter removal on any other car. I don't know if there are any extra steps on the V-12 model, but I don't see why there would be.
-Take off the starter
-Take off exhaust system under transmission
-Take off driveshaft
-Disconnect electrical connections and transmission lines from the transmission
-Remove the torque converter bolts from the flywheel
-Remove the transmission mounts and bell housing bolts with jack under transmission
-Lower transmission and pull out the torque converter
If you've heard of any extra steps on the V-12 models, I'd be interested in hearing them just out of curiousity.
I have not done it, I could pull out the steps for removal/installation for the 2000 750 . It is a little bit confusing since I didn't pull the pictures too. I will try that later ... Hope it helps :

i HAVE DONE THIS, BUT IT WAS ON A STAND.
I have removed a torque converter and I did not use a special tool, but the engine was sitting on the floor. I hoisted the engine up and there is an access hole in the bottom of the engine, point a socket back, facing the rear of the engine, and shoot a bolt off one at a time, turning the engine over between bolts. I did not use a special tool.
I don;t know if this will help or not.
