Title: Auto Trans - 722.6 Oil Leaks From Electrical Connection

Alldata.com has a list of all tsbs for most manufacturers. They charge $14.95/year or you may have a free ride with Autozone if you have the card. My library in Tempe gives free access to ALLDATA and only charges for pages printed.

There may be others and your SA should know about them but it's a lot of reading that they sometimes avoid.

Good luck,
