Grey sludge

I don't know if I have a problem or not. As some of you may have read, I've been putting a new shortblock in my car after a nasty encounter with deep water. I was just getting ready to put the motor/transmission in when I decided to pull the transmission pan and give it a quick look.

The fluid I had drained looked good, and the transmission has always shifted ok. But when I pulled the pan the magnet was covered in grey sludge, and there was some lining the bottom of the pan. I don't think thats normal. Any ideas of how much (if any) trouble I may be looking at? I put a new filter in it, cleaned out the pan with brake cleaner, wiped it clean and buttoned it back up. Of course fresh Mercon V is going in as soon as everything is installed and buttoned up.

Sounds normal to me, as long as you don't see metal shavings on the magnet! Think of taking any pictures? Was it excessive?

It's not a 97 Sport, it just looks like one!

I worked in a trans shop about 8 years and that looks normal to me and the fluid looks good.

Yep, I've seen that every time I've dropped the pan (on four different 4R70Ws).

Its normal even my DD unit I dropped after many many miles shows some of that on the magnet. The fluid is blood red too so you can have that as part of normal wear and tear. Its tiny microscopic shavings.

agreed. every trans is gonna have a bit of clutch material and metal flakes come off during normal operation, that's why they put that magnet in their. it just collects it so its not floating around and blowing the lip seals or building up in the valve body. as long as you didn't see any large chunks of thrust washers or something lying in the pan, don't worry about it.

Same here, 'cept Torqueflites. The stuff isn't circulating around the tranny; it stays at the bottom of the pan and on the magnet. Still wise to clean it out as best as you can though since you have the pan down.
