Yeah those pics kinda bugged me too.... Looks like the trans got severely overheated at one point or another and the Friction material is shot...

I threw this pic in Matts thread, Its my 4T60-E, but even after 2 hard years of heat and abuse this is all that was in my pan...

Even the 91 comes out about the same.... I never thought that my THM-440T4 would have ever lasted this long( 122,000 Miles and counting ).... I'll be doing the 95 pretty soon tho, I'll have to get more pics....

I agree tho, judging from whats in the bottom of that pan I'd say its just a matter of time... Kinda supprised tho, the 2.97 trannies usually seem to last...

I doo feel that a lot of the issues that these THM440-T4'* had were heat related... I have seen too many caddy 4.5'* fry these transmissions to death, and they had the external cooler.....

But at 16 years its possible for the unit to be done for...

I'd say just add the new fluid and go from there...

If it was a 3.33 GX3 trans we know it wouldn't have made it this far

ffffffffffffuuuuuuuuuuccccccckkkkkkK!!!!!!!!!!!!!! !

Okay, well.. this sucks. Should I start shopping for a new tranny? Because it has never worked better.. it doesn't make sense. However, the last recorded filter change was at 70k. But my mom says it happened again at 110k or 120k. So, I don't know how long it'* been there. The fluid never smelled burnt, but as soon as I flushed it, and left the atf in the pan overnight in my closed garage, it smelled so overwhelmingly burnt and bad, I couldn't even set foot in the garage for a few days, it was that bad. It looked decent, like it wasn't completely pitch black, but it wasn't cherry red either. If these are the death signs, about how long do you guys think she has left? What can I do to preserve it?

On another shitty note, I finally got around to cleaning the inside of my valve covers.. and the front one is severely damaged from three rockers [all intake valves]. It'* pretty banged up. It makes sense though, because the front rockers weren't torqued down properly when I pulled the heads. They were barely hand tight.. and i'm surprised the rockers even stayed on the rods. The rockers don't appear to have been damaged, and the oil on them looks like this wasn't recent.. should I be worried about this too?

I would definantly worry about the rockers, make sure that they're tightened down CORRECTLY before you put it all back together.

As for the trans.....who know'* when it could go....but I can say not too long. And to try and preserve it, definantly would quit beating the ever lovin **** out of it when you're down. Just drive her nice, and start shopping.

Okay, as far as the rockers go, they were fine before, and I just checked them, and they are still torqued down to 28ft lbs. So it definitely wasn't from recently. Any suggestions for loctite or something? I used blue before.. but after pulling a bolt, it seems to have disappeared.

I just got the rear header off, and right now i'm going to pull the heads. The tranny is all bolted back up, torqued properly, to 10 ft lbs, criss-cross torquing. Don't worry, I already learned the hard way with these damn oil pans.. they like their torque sequence

Alright guys, everything is off.. all the mysteries are solved.. or not.

Here are the pics of everything.. the circled stuff is actual wetness [all of which are coolant], anything else you see is just poor lighting. Also, there is one pic [it'* labelled] where the head gasket didn't quite seal like it did in other places, and I looked at the bolt, and one of the threads are all fucked. I forgot to snap a pic, but next time I go out for a photo-op, i'll be sure to snap one of the bolt. And that bolt wasn't torqued down quite as much as the others.. like I didn't even need the cheater bar for it, so idk if the block threads are fucked up, or if it is just the bolt. I've yet to look at it.

These are the valve covers [obviously]. Look how clean they are! The outter portion of them matches the inside in their cleanliness. Look at the front [top] valve cover, you can see what I mean. The rear [bottom] valve cover has it too, now that I look at it, but it doesn't seem as bad, and it'* only for one rocker.


Nice shot of the front cylinder bank. Forgot to circle one spot, top left corner.. that coolant port. That'* wet.


Close-up shot of the wetness on the front cylinder bank.. this is circled.


This is the rear bank, the circled part is NOT wet, however that is where the gasket didn't seem to look quite the same as the rest of the gasket area. Not sure if that means anything, that is also the spot where the bolt that had the damaged threads, that was the one in that corner.


Close-up of the above spot.


Head gaskets, labeled F for front, and R for rear, obviously. The lighting in that pic sucks, so you really can't see anything, and there isn't a whole lot to see anyways.. the front head gasket had some oil on the center cylinder bottom thing.. not sure how or why that got there.


I'm guessing this was the head that leaked.. this is the only spot at which the water trail goes to the combustion chamber.. it'* the one with the pretty lines around it. This is the front head, and the partial gasket you see, is also for the front head.


Again, self explainatory.. rear head.. water, and the bad sealing in that same spot.


Blasted! You can tell something wasn't right.. there was something really gross burning off. All exhaust tubing [headers, crossover, and input to cat-back] has that ****.. i just chose to take a pic of that header. Not cool guys.. not cool. Not sure what that could be.. but i know it'* not supposed to look like that.
