Just did 4.8is transmission oil pan drop and filter.

[SlickGT1]

So yea just as the title states, I just finished the trans filter, oil pan, and refill, on my 4.8is. Here are my thoughts and opinions so far.

Thanks to other members on here for giving advice about this, it wasn't bad.

Well, catching all that oil is such a bitch.

1. I should have opened up the Fill hole first. You need a 17mm hex. I didn't, and when I did, a lot more oil came out. I was ready, by my arm got caught.
2. So yea, second, you should open drain bolt, waiting for drip a bit. 14mm hex.
3. Start dropping the pan. I took off all the bolts toward the rear of the car.
Loosened the front of the car ones, but left in place still in contact with pan. Then take out alternating side screws, and the pan will drop a bit down in the rear. A LOT more oil comes out. I mean a lot. Be ready with a bucket. I was on two pairs of ramps, so a compound bucket fit underneath. T27 Torx socket needed.
4. Take out pan. Pull down filter. Oh look, that gasket that is supposed to be on the filter housing, its still stuck up in the trans. I get out my pic, 30 min later there is still gasket in there. I am trying to be careful not to flick shavings anywhere.
5. Shit is still dripping on you, so you will need rags.
6. Putting in the new filter was tricky too. Almost seems like the pan holds it up. I can tell because there are worn metal marks on the pan where the filter legs shit. But it goes in tight.
7. Bake cleaner on contact surfaces. It stinks, I forget this from time to time, but it is pungent, so ventilated area is preferred. Cleaned out the pan, and removed magnets. I was shocked, to find nothing on my magnets. No fuzzy metal shavings nothing. There seemed to see be some sludge on magnets. I bit dirtier oil really. I was able to wipe it off with a finger. Yea no shavings at all. 77.5K miles. Strange.
8. Dropped one magnet against my tile floor. It broke in to 2pc, and a small wedge. I put back in the two bigger parts, and I guess, I will be dropping the pan again sometime soon. Yay to me.
9. Gasket, some bolts, an 18V screw driver, everything back in place. Torque specks are 9 N-m, so make sure you are equipped with one that goes that low.
10. Clean up some, and pump in some oil. I picked up a cheapo $15 buck one from Amazon, but I won't give you the link because it sucks. It like 2ml per pump, the cap didn't screw on, and it didn't reach bottom. Might work on of the shelf bottles though. I used ZF LIve 6.
11. Fill it up. I noticed that you need to get your finger in there, and feed the tube in deeper. If not deep enough, it will leak out early when pumping.
12. Car took about 3.5 Liters. Started leaking out.
13. Started it up, ran through gears and killed it. Took out fill bolt again, put in about another 1L.
14. Ran car with for a bit, like 10 min trying out gears, ac on. Car running, friend at GT1, (I would get instructions how to do this, and I will later, but I was all in oil, and didn't want to touch someone else's pc at all. So my time was on the floor most of the time). Reached temp reached 40C. I was about done topping off, it started leaking out, hot by the way, so wear gloves and don't touch the exhaust.
15. Put fill hole plug back and done.
16. Going to do this later when I get a new magnet, so at least it will be a decent amount off oil swapped out by the two fills.

So I took it for a drive, seems to drive still, so that's. Seems a lot smoother 1 to 2 shift. Performance wise, it seems to stay the same as far as the speed of the shifts and all that. Tore the shit out of the car to the point, my mileage now reads. 11.5mpg. That's 12.7. It also seems to be shifting in reverse quicker. After abusing the car, aka: having shit ton of fun, it used to take a solid 2 seconds to go into reverse, very quick now.

We will see how it goes. I'll update later. Got some errands to run.
