I was thinking along the lines that the filter could be plugged... But judging by the fluid I was almost afraid if we changed it we would not have gotten the car around the block...

You have gotten aquainted with the scantool I see

If it says TCC failure... I don't know what to tell you...

What codes were you getting from it?

DTC 39 - Toque Converter Clutch Problem. And that is the ONLY code it is spitting out.

That could simply be too much slip. Let'* get a filter/fluid change. It'* worth it. Might end up being a waste, but it might save you too.

Ok, as soon as I got home from work I dove into getting this fluid out (despite the warnings of apartment management). Tomorrow if I have time I am going to filter the old fluid just to see if there are any metal shavings I should know about, but preliminary inspection showed no shavings, but a bunch of gunk...and some clutch material.

I put a gallon of fluid in, plus a quart of Lucas to help stabilize the old fluid, and I don't think that is enough. But I did drive it around afterwards just to get things flowing. First gear is definately there, but there is still slippage, now there is TCC shudder (so I now know the solenoid is engaging), and traction control is still kicking off (I think the thermoswitch is out of adjustment) because I can put my hand on the trans cooler and it is comfortable enough to touch and hold it. It DID hit all the gears, just slipping like crazy.

They say a picture is worth a 1000 words. I hate to say this, but judging by the looks of that sludge at the bottom of the pan, your transmission is toast. Go conversate with a local privately owned shop that'* been around forever, and if you want to change the final drive ratio, now'* the time to do it.

BTW, do you have canary island pines around your apartment building?

Yeah, after looking through the pics I took I am wondering just how many miles I have left on this unit. Hopefully long enough to last until March or April once all the fluid has been changed out of it

I also put in an adjustable modulator, which once I get that tuned in may help with some of the problems I am facing, but the one that worries me the most is the trans temp switch kicking off the traction control. There is no way my trans is getting that hot that quickly...unless...I have a plugged line or the aux. cooler is plugged, which with all the sludge that was in the pan, could be a very real possibility. This could also cause line pressures to drop to, right? Hmmm....sounds like another test tonight.

Uh Brad.. what material are those pieces made out of? I'm with Mac on this one.. "What'* that sludge in there?"

It'll last til March/April if you don't drive it, I don't believe it'll make it any other way.

Or by towing it with another vehicle, but those are the only two ways. Sorry man, that tranny is done.

Thats an extreme amount of friction material on the bottom of the pan... Whats on the pan is more everything on the clutches... almost looks like it was never changed... Sorry to see it Buddy...

Oh and those pieces in the pan appear to be thrust washers...
