If you get a trans from one of the vendors it will have the fix already applied.

This is worth a try as a last resort along with the trans tune cleaning, filter change, Lucas stop slip, transgo or DIY shift kit and line pressure adjustment.

*Before adding the transtune cleaner put a strong magnet on the outside of the pan to collect any additional debris the clogged inside magnet may miss. run the trans tune cleaner for a week or two before pulling the pan for the attempted fix.

For a diagram of the trans pan for exact magnet placement, see http://www.grandprixforums.net/threa...ighlight=4T65E. Page 5, reply #91
