Alright when should the fluid in the transmission be changed?

GM says 100,000 miles but I'll change mine around 50,000 miles or so. Same goes for changing spark plugs and engine coolant, 100,000 miles is just way too long to leave any of that stuff in there.

Yeah I think that maybe a good time to do it. Send the car in and have all that done on the same day.

I'll do it all myself, I'm not paying them $100 an hour for something I can do easily.

You have the machine to flush out the torque converter?

They will most likely tell you to come back later, and complain about it voiding the warranty or something.

The dealer that I bought the car from seemed to be pretty good. I don't think they will hassle me.

My dealer is great too, I stopped by to ask about a burned out foglight bulb and they replaced it for free right on the spot. I don't have a machine to flush the trans but dropping the pan replaces a lot of the fluid, plus I can change the trans filter. I've always done that with all my cars and never had any issues.

Yeah I heard a few guys done that before without any problems. Sad part is that I am pretty sure my 06 GP had a dipstick for the tranny fluid, and the G8 doesn't.

Just use a hose or a funnel with a long spout to fill the trans.

Seems like it wont be easy filling the trans when it's empty. I do see a drain in the bottom of the pan though which is a plus.

Yeah specially when you're lying on your back. The drain plug in the pan is nice to see, it's a mess to drain the pan by loosening the bolts and letting it flow all over.

Yea, I'm not sure if the filter is replaceable any more, I know at work we just drain them and fill them.

The G8 does have a replaceable filter, which is one reason I don't like to have it flushed, since the filter doesn't get replaced. Besides I've heard of people having trans problems after a flush, so sometimes it does more harm than good.

If the pan is removed and the filter is replaced it holds 6 quarts.

I think Don made a good point about flushing the trans. I have also heard some bad news after guys do that. The car has only 10,000 miles anyway, I have some time left.

I have 33,000 on mine because I bought it used, so I might be changing the trans fluid in about a year, along with spark plugs & engine coolant too.

I try buddy. I could probably get Todd to give me a hand with spark plugs. Maybe we can do it once I get the magnacharger, Kill 2 birds with one stone.

I was changing spark plugs when I was 14 years old, so you don't need any help from Todd. I'm gonna call him up and let him know this too.
