My 1990 740 goes through about a quart of ATF every 2 days. I'm not sure what it is called but the Aluminum tube that runs from the ATF dip stick down to the Transmission has a crack in it, I can see the drips start at the bottom of the bend when I pour in the ATF. What is the name of that tube, and where can I get one? What other advice can you give me re: leakage of ATF? Thank you.

 

the Transmission dipstick tube or fill tube

Pretty easy to replace, odd that it cracked however, perhaps its simply loose?

new they are between $40-$60

Used $5-$20

 

Thanks, Nichas!
