Hey car guys, I want your guys' opinion.

I have a 2006 Pontiac G6. It has a sealed transmission. The car has 72K on it. The service schedule in the manual states that the transmission fluid should be changed at 75K.
I'm a little nervous about getting it flushed. First it's going to cost about a bazillion dollars (roughly). But the transmission has been functioning well, and I'm concerned that disturbing the seals and gaskets to get it flushed may increase the probability of a leak. If there is no real risk of transmission damage by not getting it flushed, it obviously won't be worth it. What are your guys' thoughts? FWIW my dad is an old farmer that knows a lot about motors and he suggested I leave it alone until the fluid begins to change colors.


A few other facts:
1. Transmission shifts fine and on-time.
2. Gears still feel tight when putting the car in drive.
3. Upon inspection, no transmission fluid leaks.
4. The fluid in the reservior still has very very good color. Nice and pink, not dingy at all.
5. Engine/transmission has not been worked hard at all exempting when I got stuck in a snow drift.

Who needs transmission fluid. Drain it out so you don't have to worry about it.

Then fill it with antifreeze?

I've never seen a vehicle with a transmission fluid reservoir. What you're looking at is likely the coolant.

Either way, if it says 75k, I'd get it changed around then. That's the best way to protect from damage. Just cause it looks good doesn't mean anything about the chemical properties of the fluid.

It should cost somewhere around $100, and that's cheap insurance, IMO.

It is sealed. There is no dipstick. I'm pretty sure it was trans fluid. I'll check again when I get hime, but I'm pretty sure it was trans fluid.

Hmm, even the "sealed" units (i.e. no droppable pan) that I've seen have a dipstick to check fluid levels. I'd like to get a look at that thing.

Either way, my advice is to get it flushed. Most horror stories about flushings are from people who haven't taken care of their vehicle, then they finally get it flushed way past recommended intervals, and surprisingly enough, after years of abuse, the tranny develops problems. Then they blame it on the flush.

nope some have a plug that you pull on the passenger side next to the CV shaft. also has a fill plug usually right under the exhaust crossover pipe. the fluid he is looking at is most likely the power steering fluid. if you have a pan and drop it to refill you pull the plug on the side and fill with trans fluid through the hole under the XOVER pipe until it dribbles out of the hole on the side by the CV shaft.

Could be. I could have went full retard for a moment in what I was looking at. So what's your advice, jason?

I don't flush my transmissions, however, I do change the oil in them. It's pretty simple, just drain, and then fill through the dipstick hole.

Now keep in mind, drain and fill won't get all of the fluid out, but, it will cut it into about half on most cars. So, the next time you change it, it will change half of that, etc., etc.

After having tranny problems (yes, it was after flushing - but as the person said in the other thread above, it hadn't seen regular maint.), now I'm a big fan of just doing a tranny filter and oil change.

My 2 cents.

A lot of the newer vehicles don't have an actual dipstick. We work on a ton of them that are a "drain and refill". You have a plug in the bottom you remove, and if fluid comes out it's full, if not you add from the top till it comes out the bottom, pretty simple. Most of these transmissions filters are a change only when the transmission is dissasembled. Now some of them like the saturns will have an external spin on filter you can change when you drain the fluid though. My 08 Charger has a transmission dipstick with a cap that says dealer use only, but you can actually make a dipstick to a certain measurement to check the fluid level, we have fashioned a few of these to use.

Yes sir you are correct, you wouldn't believe how many cars we check where people think it's the trans fluid but it's the coolant, it can be a little confusing.

Hey guys, my car seems to have some trouble going. The temperature on the panel shows it leaning towards the H, and I check the thermo valve, nothing broke and no coolant leak either. Any advice?

i wouldnt have it flushed unless they also change the filter, i THINK your trans has a removable pan, if so thats what i would do, someone here works at a trans shop(kcchiefsfangoljIIRC). but if the owners manual says 75000 i would stick with that. i recommend not to touch it if you go over 100,000-125,000, but now i dont think would hurt.

Yeah, I'm not reading to well tonight, I sent him a pm about manual transmissions for some reason. I thought he said it was a manual :doh!:. If it's an automatic it should have a 4T45E transmission, and yes you can drop the pan and replace the filter. It's recommended to change the fluid every 20-30k, we usually check the condition of the fluid and then recommend what to do. We actually don't flush them as a maintenance thing, I will always recommend to change the filter, and clean out the pan.

I figure there's gota be atleast fill spot somewhere on that tranny. Draining wouldn't be a problem, pop the line at the radiator and let the tranny pump do the flushing, but even GM had to get fluid in it somehow.


And Buehler, you don't flush the transmission when it starts acting up - by then it's too late. You flush when everything is still fine so it doesn't act up. If you don't get it flushed, it WILL act up.

actually the parts store shows 3 different options. but yeah they all have a pan. land i would NOT let the pump run the trans dry by unhooking the cooler line(sorry pastor). and follow the bolded part

F******* I'm retarded. I looked at the manual again and it said to change the fluid ever 50K if you drive in bad conditions - which I don't.

The 75K deal came from an extended warranty deal that this mechanic shop tried to sell me. Which I'm not going to do.

NEVERMIND :doh!:

has it ever been done? and FWIW i have seen MANY extended service plans and most dont pay for much of anything, even if they say they do. funniest one to me was the time a lady( about 70 yrs old) bought a tahoe with 92,000 miles on it, they sold her an ESP with a 5 year 100,000 mile limit. she comes in with a water pump leaking. they wouldnt pay because she had 101,000 miles on it. she paid 1,300$ for it and everyone told her that it was good for 5 yrs 100,000 miles. actually it's good for 5 years or 100,000 ACTUAL VEHICLE miles. so for 1,300 she got 8,000 mile warranty that she never used. talk about a fucking. who would think that was how it worked?

I bought the car with 22K on it and haven't done it.

I'm not going to buy the extended warranty. Those are usually a good boning without lube. This is from an independent company, but you have to have EVERYTHIHNG done, so I'm sure it would cost me a ton of money.

you should probably do it then. are you mechanically inclined at all?


and on the ESP the one i referenced was an aftermarket also, and what you said was right

Nah, I'll be OK. I'm pretty solid. At least have an understanding. Hate me some wrenches though.
