94 SL600 couple of seals and part numbers need some help seriously!!
 

My 94SL600 transmission started leaking last month, and I have to add some fluid almost everyweek, Dealership told me the pan gasket and some other seals have to be replaced, the part numbers they gave me are as follows,

0126-271-10-80 Pan gasket
0140-277-01-51 Its a small white spacer, I have no idea where it goes to!
0016-997-34-48 A small seal again I have no idea where it goes to!
0005-997-80-48 Another small seal and I have no idea where this one will go !
0016-997-35-48 Another seal and dont know where to install this one either.

Does anyone know these parts numbers and where are they supposed to go!

Dealer wanted to charge me $600 for these parts to be put on! I refused it and bought the parts to install it myself I really need some advise here guys.

I dont want to pull out the Vacuum modulator or shift linkage with not knowing where to install these seals, also I know If I pull out the modulator it will be a messy work and I have to check and adjust the pressure.

Items 301, 299, 300, and 304 and a pan gasket.

Thanks steve, from the picture, I assume, I will have to remove the over load protection switch and reach to those seals do you think its going to be a messy job any points I have to pay attention to? Thanks for your help.
