i gave you mine, so where is your evidence that they tear up more because of lack of fluid change. i really want to hear this. dont want to hear no crap about the seals will be softer and keep them from leaking, 10,000 mile AT fluid will keep them as soft as new AT fluid.

Well I just came from the 94-96 impala/caprice board where over the last 8 years I monitored what broke and at what mileage. most of the folks on the board kept there cars for more than 6 years and went way over 100k miles. many of them are still driving them. a very few trannies broke early on. most did go out at 50-80k range. people acknowledged they had not done much, if any, maintenance. Professional tranny builders on the board advised changing fluid more often. Several dealer's shop folks asked me about my deep tranny pan with drain plug and I always told them the frequency with which I changed oil in the pan. everytime, they said it would make the tranny last longer. I was able to get about 160k out of a hard driven automatic and it is still running great today with another owner. That was the first tranny I changed fluid on so often. The prior 3 other vehicles of my own failed in the 80k range with no transmission maintenance. I don't doubt that some folks get more mileage than I did with no maintenance.

any lubricant wears out due to shear and heat. I think asking tranny fluid to still work right after 100k miles is just unrealistic. Usually, the mfg says to change it at 50k in severe usage. I have seen people do that and then the tranny fail within a few weeks or a thousand miles - many times. It happened to me once on a pontiac I had before the 3 noted above when I did change fluid late like that. I did have good luck changing more often. Its way cheaper than a rebuild or new transmission. I just think of it as insurance cause I know I'm gonna have this truck for 6-8 years and drive 20k a year.

I think the manufacturers know how long one will last without maintenance and they want to sell you one sometime down the road. I don't think you'll be convinced and I'm not worrying about it. good luck. juma

New AT fluid will not keep these things from happening. the planetary and sun gears were bad in my dads tahoe, sometimes they break just like anything else.

The fluid life expectancy is directly related to the operating temperature of the transmission. Normal operating temperature is about 215 degrees Fahrenheit, but the cooling efficiency of you vehicle's cooling system and the type of driving you do will be the real determinate of it's life expectancy. At 215 degrees, it should go for 100,000 miles, but for each additional 20 degrees, the mileage is cut in half.

I'm really curious where you get these numbers from

Also planetary gear failure is fair from the most common failure in an automatic transmission. Many transmissions 100,000 + are rebuilt with the original planetary gear sets. More commen that planaty gear set failure is one way clutch breakage particularly in cirtian transmissions on of the most notable being the ford Aod/aod-3 ford now recomends an upgrade to a mechanical diode owc with a rebuild on my applications. How ever to get back to the orignal point mechanical component failure can easily be caused by dirty trans fuild. Just like dirty engine oil it gets saturated with particals from friction material,metal shavings ect. The additives also break down with age. Now weather tranny fluid needs to be changed after 10,000 k of street usage I doubt how*ever 40-60,000 miles wouldn't be a bad idea

these Numbers came from several websites, after i took the notion to research how long AT fluid would last. go to yahoo, search around and youll find it.

Obviously changing fluid in anything will help. i try to keep all my fluids in very good shape. unllike my dad or grandpaw, i am on titan talk and other forums shooting the ****. and looking at what everybody else is doing.

my dad has a work truck 1994 chevy 1500 w/t it has 178,000 hard miles on it. here is his schedule. 10,000 mile oil and filter changes and that is it. seriously he has never changed AT fluid. we have looked at it a couple times and it is as bright red as it was when it was new.

im different: when it comes to 50,000 miles ill Change about everything.

my question is when does changing fluids change from something good to just wasting your money? changing AT Fluid every 10,000 to 20,000 seems like a waste to me. not to mention its about 90$ a whack For AT fluid change in a titan.

i didnt mention this earlier but driving style has alot to do with it. if you brake torque your vehicle alot it will eventually take its toll on the tranny. if you live in a place like me where there are hills and curvy roads and leave the tranny in drive and just let it shift in and out 4 and drive im sure that will eventually hurt it. that is why i usally drive in a gear to where it doesnt have to shift so often. these things can really hurt a tranny, my buddy doing his brake torques finally burnt his tranny up.

new trucks have a warranty also, mine has 100,000 miles so im not going to waste my money on changing things before they are due. if it wants to break let it break.

Just my Opinion. in the end everybody does thing different. So if it works for you then do it.

just to clarify, when I said I changed the fluid, it was just the 4 quarts in the pan, for the most part. there was a couple of times I dumped the whole system but after I got a pan with a drain plug, I just went with changing the pan. juma.

GETSOMZ28 · 10-28-2004, 07:19 AM

smoothTitan, the only way to know for sure how long a certain fluid will last is to do a analysis on it. Everything else is just guessing.

smoothTitan · 10-28-2004, 11:18 AM

oh ok. it is alot easier with a drain plug for sure.

smoothTitan · 10-28-2004, 11:22 AM

there is another guy on here somewhere who is dumping the whole sytem, like 9 quarts or something, every 10,000 miles.

so anyways no hard feelings toward any fellow titan owners, just like to talk about these things and see what everyones opinions are.

GETSOMZ28 · 10-28-2004, 11:47 AM

No doubt smoothTitan! I feel replacing the all the tranny fluid every 10K is overkill (and not cheap). I would think replacing it all every 30K or just what is in the pan (~4qts) every 15K or so would be sufficient.

Everyone has their own take as we can see from this thread.

why though would you think its a must to change your differential fluid right away but not your tranny, ever? also, I gotta question your practice of changing rotors with every brake job- whats up with that? soft spots on the rotors - give me a url for that one as it seems a little farfetched. no hard feelings, just want to hear your full opinion on these matters.

smoothTitan · 10-28-2004, 05:33 PM

well actually i didnt think it was a must to change the diff fluid right away, but with all the people on here talking about it was low from factory and excess metal shavings, i figured i would change it.

ok, i usually turn the rotors myself at my buddies parts store. and after doing this a few times i noticed after about 3000 to 5000 miles i would get that shake in the front end when i applied the brakes, so then i would have to go through the trouble of taking them all back off. from my experience once the rotors get soft places in them it is very hard to get it off, you have to take alot of metal off.

It works better for me this way, and i get more life out of my pads.

like z said everyone has their own way,

well you went from somebody "is obsessed" to "everyone has their own way" and I think thats good...and I didn't even have to get into grill obsession

smoothTitan · 10-28-2004, 08:55 PM

i wasnt gettin anywhere with the obsession, so i figured i wouldnt make this just a blazing thread.
anyways i got what i wanted to say out.

grill obsession?

just noticed you posted a lot on grills for the front of your titan...

I have never heard of these soft spots on the rotor you speak of, rotors are not heat treated, surface hardenend hence they should be the same hardness all the way through.

smoothTitan · 10-29-2004, 07:43 PM

lol you have alot of time on your hands, dont you.

its pretty sad that somebody would actually go back through and read the posts that someone else has made. i can say that i have never resarched someone elses posts inorder to get or try to get the upper hand.

i think i can ask a few questions about grilles for my truck. far from an obsession.

so you are saying that anyone on here who asked asked a couple questions about products for their trucks has an obsession. thats pretty funny.
