hey all,

i have a manual transmission from a late model 240d bolted on my om617a engine. the bellhousing is a single piece of aluminum, for reference.

this is what the pin nut on the output flange looks like:



i see that pelican parts has two tools for these nuts, the sirtools m0029 and the sirtools m0032. they only list the compatible automatic transmissions so i am not sure which to purchase. i don't want to buy one blind since returns apparently are not accepted on tools.

anyone have any idea which will work with my transmission?

i was going to go with the drift punch method, but i don't feel like dropping the trans and would rather just buy the correct impact socket

thanks!
