Newly acquired hooptie for my daughter. Nice fixerupper. Main issue before she gets her hands on this..... is the transmission. Mostly it is fine, occassinally it will slip ONLY while turning? What up? My first thought is a clogged transmission filter? For the expense and the effort I got little to lose? Any thoughts?

I assume you have already checked the fluid level because that is what it sounds like.

Yes, the fluid is checked. It is black....so let's keep our fingers crossed. Only slips when turning, otherwise fine. Thanks for the great response as usual.
FYI, I worked on cars out of necessity as a teenager. As a result, I drove better than average wheels. Although I got away from the dirt and grease, I always liked my cars, and never lost my confidence that good mechanix and patience provides results. I am now 57 yo and been kicked around in life. I am back to the necessity thing, but today I have a Saviour!!!! Faith, good mechanix, and patience will come thru everytime. Because of CarJunky I am really ENJOYING myself, and find that I am eager to invest in tools and knowledge. I am unafraid to tackle auto mechanix, patience with diagnosis, good information, solid plans, safety first, and friends. Thank you CarJunky and all the contributors and facilitators!!!!!!!!!!!God Bless everyone!!
Now I am out to the garage.

If the fluid is black, that trans is pretty much used up. That is clutch material that turns it that color.

I agree, you definitely got a hooptie...or more like pooptie. Fluid black and burnt, so is your wallet.

Got a AT filter kit & some fluid. Drained about 3 qts of fluid (measured out) and dropped the AT pan. First thing: one of the 2 magnets was out of place and jammed up in a perpedicular fashion. Nothing was bent or broken or appeared out of place. Although the fluid was black, it seems thicker than it looks. Crankcase oil that color seems like water.
Anyways, put it all back. Put fliuid back in. AND??????.....no slip.....then slipped a little... then no slip... then all is good? That was 3 days ago. I have driven it everyday since....no slip. Straight (never was a problem) or in a turn (original problem)....no more slip. Cold or warm, no slip.
Now this may or may not be associated, but this hooptie purrs like a kitten in park. A bit rough when it is cold, but after it warms up it idles fine. But falters once placed in gear (forward or reverse) if I keep it alive it runs great. Of course, slowing down for a turn it will stumple, and, at an intersection we need to use Neutral to keep it alive. Although this performance can be associated with the AT, I hestiate to go that far (wishful perhaps) since it now shifts like a 2013, OD or otherwise. In fact, I believe if the OD engages it is a sign of an operational torque converter?
I changed the Cap&rotor, spray cleaned the throttle plate, double checked the MAF, pulled the various relay connections and cleaned with Elec. Spray Cleaner, checked vac leaks (none evident).
Comments?

So an improvement with just 3 qts new ATF. I still think this trans is burned up just by fluid color. If you want to toss some buck get the entire amount of fluid out for new.
It may be sloshing to one side, and pump can't pick up enough fluid so slips would explain it but it may have already killed this trans no matter what the cause was first. Your call,

OD means any gear ratio higher than 1:1. OD on a four speed automatic is 4th gear. Lock up and OD are not the same. Lock up means the torque converter clutch has engaged. The transmission doesn't have to be in OD for the TCC to lock up unless it was something like a Ford AOD. Infact, 125C is a prime example. The 125C is a three speed with no OD, but it does have an electronically controlled TCC.
Black burnt fluid means transmission clutch components are slipping. That produces a lot of heat. I am sure there some smoked clutches in that, but time will tell if the problem rears its ugly head again.
