2001 X5 After trans flush has shudder symptoms and torque converter not locking up

Any issue with passage or particulates impeding flow and operation would be limited to the valve body. If your fluid ops don't bring joy, then drain and strain and save that spendy fluid, pop the pan back off, grab ya a pic/diagram that shows the specific screws that hold the valve body in place, and pop off that valve body. Take to bench, disassemble one section at a time, clean and reassy in like fashion (get gaskets)

Amazing how much little goopy stuff you will find hanging out in nooks and crannies. Most of a Saturday is more than enough time to do a thorough clean and inspect.

But make sure the fluid level is correct first, as per the detailed instructions posted above.

And make sure that the above job is within your capabilities before starting. You will need a kit from CTSC with gaskets and various seals for the valve body. Test the temperature sensor as well, since your problem changes from cold to hot. The valve body is a detailed job, everything has to go back the way it came apart. There are lots of small pieces. It isn't something to rush through. /end warnings.

Sounds good, but not for me.

I took one shot at rebuilding a manual and automatic transmission. Never without experienced help.

There are some things you can have some stuff left over when you are done and it still works fine, like maybe a vacuum cleaner. A transmission is certainly not one of those.

If I am working on something for the first time and a part(s) fall out unexpectedly it is always an O-s##t event. Sometimes it is logical where that part belongs that was not the case with a transmission. Even when that has not happened, I would pick up a part and not be any way near sure where it should go.

Great fun I always thought valve bodies were neat to work on. But they're not for everyone.

Very cool photos.

.....and if anyone ever needs any spares or vacuum testing doing, just give me a shout

You would become a superhero--Tranny Man--able to ease all apprehension, saving the miserable, the forlorn, from the rack of pain and suffering from tranny death, end the paralysis of to do or not to DIY, the master of gears that go, clutches that hold and convertors that lock.

And, if you improved the durability and performance ---you would be rewarded with gold and silver, accolades and glory, enshrined in the BMW DIY garage of fame, forever.
