535 manual transmission popping out of 1st.
2011 535i manual transmission, 100K miles, original tranny oil (I assume)
Car was fine, wife went away for 2 weeks, the car was not driven. She came back and now it pops out of 1st gear 50%+ of the time.
Research has pointed to 3 possible causes:
Bad/old/low tranny fluid
Bad tranny mounts
Bad 1st gear synchros
When accelerating in 1st gear the shifter seems to float a bit,maybe an inch of total of movement (tranny mounts?)
I had her try to stop, push in clutch, put in second then 1st, then release clutch and accelerate, she reported that it still popped (is this a valid test for synchros?)
I tried to hold it in 1st, it popped out and as I tried to hold it...... it just ground a bit and didnt engage. (points towards synchros?)
My plan of attack is to do fluid change and mounts and cross my fingers.
The first thing I need help with is finding the PN and quantity for the manual tranny mount bushings. Never heard of a single mount, but thats what the diagram looks like.
Real OEM says it is 22316770289. But when I search google for that number 99% tells me that it is for automatic transmissions. The others say auto and manual.

Can anyone confirm that the manual and auto tranny uses the same bushing? Any DIY's around for F10's Ive done them before on E10, E46, E34.... etc. But never a non round single mount.
I will keep everyone updated, hopefully this isnt a tranny rebuild

Update
The tranny mount is indeed 22316770289 (same as auto), and a qty of 1. its just one large one in the middle
No DIY needed, remove 13mm nut on top and bottom of mount, raise tranny a bit, remove 13mm bolts that hold on cross bracket, take out bracket, replace mount....... reverse.
Changed fluid. Drained into a jug, then put an old hdd magnet in the jug and sloshed it around to grab all the metal that existed in the fluid. I then strained the fluid as i poured it out into a drain pan. Attached picture is the results.
At the end of the day, it still pops out of 1st gear
F**Kety F** F**K!!!!!!I will probably move this to a more general discussion since the only F10 issue was the PN.
