possible leak??, help with e153 tranny Options

[celicaGT96]

alright guys ive been working on a 3rd gen 3sgte swap for a lil while now..Im trying to get everything together, just taking a while cuz of $$
anyway Ill be using the e153 tranny from a 99 solara that I bought from snapshot. I have been doing little misc things with the motor and trans and I have all my swap parts in one section, so I dont lose anything. I found some pieces laying around and im not sure exactly where they came from?? Im preeetty sure theyre off a transmission but idk. The thing is I went through the auto tranny from the 5s, the e154 from the 205 and now the e153. Im only worried now about the e153 of coarse because thats what Ill be using. The LAST thing I want it to make everything all pretty and find out in the end Im leaking trans oil. These are the two Im worried about. The big one looks like it might have came from an axle but not the actual transmission. The other I JUST found next to the pile of crap and Im worried it came from the tranny. I took some pics so hopefully someone can see and confirm if everything looks right. Hope these help.
