I replaced both the 1-2 shift and the TCC solenoids. the ones in there were not delco units looking at them the markings were different. I also noticed that the 3-4 solenoid is kinda loose on it's bracket. I think I will most likely order that one and the sensor plate that lives under the filter. poured the old fluid back into the trans so I can at least test if replacing the tcc solenoid fixed the problem of it not releasing.
while I was pouring the fluid back in, I noticed a leak!!! O-crap.. crawled back under the truck and found that the dipstick has a hole in it right behind the engine plus it's loose not secured to the back of the head. welp I bet the tab that's spot welded to the tube came off and now has a hole were it was spot welded. Great, grand, wonderful LOL
I guess I will add that to the list of repairs when I finish the other engine and when this one gets pulled. it didn't leak a lot, so I'm not pulling it out right now.
That pic I posted doesn't do justice as to how dark the fluid is. while I was pouring it back in it looked like used motor oil, you cant see through it.
I will make plans to change the fluid, though idk how to get what's in the converter out too. maybe when I pull the engine I can pull the converter and dump it and refill then.
