that mystery part, at my work we call it a bopper. When we see those we know for sure the trans filter had never been changed on the car before. there is no use for it. Im not exactly sure what its intentions are

Transmission service is one area where I seem to be different then most people. I do not like the idea of flushing old dirty fluid back through the transmission. The procedure I use is to first drop and clean the pan and change the filter and add fresh fluid into the pan. Then, I may (or may not) have the transmission flushed. This way, the transmission is flushed with fresh fluid and not the dirty stuff. Yes, it will waste some new fluid but I feel so much better not having the dirty stuff being forced through those small passages in the trans.
Last time I had this done, the mechanic (a very good mechanic) said he really liked that idea in that he is not real comfortable flushing dirty fluid through the transmission and always recommended dropping the pan and this was a much better option.

The only problem with changing the filter then the fluid is that all that old dirty fluid goes through the nice clean filter. I usually flush then replace the filter so everything is clean.
