FOAM ON BLAZER RADIATOR

Well, I've already had a blast loosening all the transmission pan bolts. Hey Wolfi, is there any trick to removing the pan from the transmission? It's wedged between the transmission mount and the exhaust pipe, and I can't get it out. I want to avoid the hassle of removing the exhaust. Haha, the pan bolts weren't very tight; I could almost pull them out by hand without any effort. Cheers!

I also had that problem with my Isuzu the first time, so it's no surprise the oil pan won't come out. With practice on my truck, I learned to remove it by loosening the transmission mount, then lifting it a bit with a jack (I used the transfer case for support), since the exhaust pipe flexes a little (because of the hoses). That way, I can get it out without much trouble. Be careful when lifting the transmission so you don't hit anything on top. If your shifter is a rod type, disconnect it to avoid damaging the circuit board or the wall/neutral sensor (in my case, when I lift the transmission, I force the shifter past Park; I avoid that by putting it in Drive since it has Neutral above and 3rd below, which shift without pressing the safety button). Try removing just the mount and lifting it a little.

Don't forget to replace the gasket. Once you remove the oil pan, you can't reuse the same gasket because it will leak. If possible, install a drain plug in the oil pan in case you only need to change the oil again. Remember to tighten the oil pan gently the first time (all the bolts) and then tighten to the torque specified in the manual.

Hey Wolfi, after so much struggle, I finally got the oil pan off! I used a hydraulic jack between the transmission mount and the exhaust, and another jack lifting the transmission. I moved both jacks, and the oil pan fell off. I found remnants of a plastic zip tie that secures the wiring harness. The magnet at the bottom of the oil pan had some metallic grease on it, not much, I suppose? It just formed those lines around the magnet. There was no water, not a drop. Now for my questions: Why is the oil level so high on the dipstick? I don't have the Blazer manual, so I don't know the correct torque for the oil pan. I also have doubts about the transmission's electrical system. I still need to check the radiator. Cheers!

Greetings machonegro, it's normal to find some metallic particles on the magnet, since there's friction between metal parts. That's why the magnet is there to trap them. The amount found indicates how much wear the transmission has. If there were only a few, it means the transmission still has some useful life left. If they covered the entire magnet, then it needs repair. A broken plastic seal? That's not unusual. The cables must be somewhat stiff or hardened; the heat from the oil does that. You didn't find water, which is good news. Now we need to see what happened to that level. Calculate how many liters you drained and add about 3 liters (the amount stored in the turbine). That should give you the approximate capacity of the transmission. Check the radiator and let us know.
