i have read all the links and seen all the pictures..

my quesiton is where to buy this b2?

also do I have to remove the pan?

and talk to me about moving the transmission?

I need somemore knowledge before I go do this... I did the k1 yesterday...

The link to the article I posted, on your first thread about the k1, shows a part number for the b2
go to the dealer parts counter, give them the number

alternatively, Phil can get you this part
it's that easy

the article explains where the b2 is and how to remove and replace

again I'm posting the b2 article
read the article thoroughly

I'm sorry to tell you but you have to drain and fill yet again. Of course, you could just refuse and sell the car to me

Just reuse the gasket and fluid and don't be a crybaby

(JOKING, PLAYING AROUND, JUST KIDDING, ETC).

Quote from Sexton's writeup:
'The good news is the repair can be made while the transmission is in the car in the case of a 126 it's pretty easy - in other chassis the trans needs to be dropped just a little although people have reported success, with some effort, of doing it to 123 and 107 chassis with the tranny in place. It's not a terribly expensive repair either, the part is about $100 and it'll take you a couple of hours. While there's a few steps to this it's really only a little worse than changing a spark plug and you don't need of be a master mechanic to do this.'

Don't be afraid. If you could, please post photos for the forum
