im getin ready to do a transmission oil change on my '00 A4. i was wondering if i have to change out the filter? i went to gmpartsdirect n there was a filter w/deep sump and one w/o deep sump...so if i do decide do change the filter which one do i go with?

TIA

By the way my car has about 67K miles n i havent change the tranny fluid since i got the car (about 34K miles ago)

IMO
I would pay some body that has the machine that filters and flushes the
Tranny, not only does it get the lines, it gets the torque converter.They
say if you have this done than no you do not have to change your filter
One thing to consider is that just dropping the pan and changing the
filter does not get all the contaminated fluid out that is left in the lines
and torque converter.

Actually i would do both have the pan dropped cleaned and replace the filter,
Than have them hook the machine up that flushes the complete
tanny system. Most dealers will try to tell you the machine filtering and
flushing is all you need. I am old school and still would want my filter
changed and pan cleaned.

I was told i could get both done for around $300.00.

The corvettes only come with the deep sump pan.
I know that they don't look deep, but it is considered the deep pan.

head to your favorite Chevy dealer, and have them do both procedures, and refill with Dextron IV (Dex 4) which is what GM uses for newer models. Should be < $300.

My 2000 car, with 27k, has already had the trans ATF changed 2X.

it's really a waste of time effort and money to change the fluid on those intervals. If you destroy a transmission, a change is warranted, but otherwise you are just wasting money.

GM says that it is a 100k mile fill, and if you don't overheat your fluid by constant racing, you really could make wiser use of the money spent. It's not like the engine where you have a combustion process burning off additives and contaminating the oil.

I had 50k miles on my fluid, when I replaced my transmission, and the fluid was just as red and clean as it was coming out of the bottle.


2 cents.

Actually its recommended 5 year or 100k mile from GM.

you do not know how the car was originally driven so I would do both.
It is hared to get a good rebuilt trans without spending big bucks.

Never heard that 5 year part, are you sure you aren't making that up?

25k miles of my 50k were 'hard'. Drag racing, autocrossing, and HPDE's, not to mention mountain climbing (uphill racing).

There are much better ways to spend money, but I've said my part.

thanx for your input guys

I do not believe I am making it up. Each dealership is different, and I
swear I have read this some where that dextron should be changed every
5yr/100k. At least that was our recommended interval.

Anyway it is his money and it is well spent if it gives him piece of mind

Bought my '02 with 47,000 miles on it and about the first thing I had done is the "complete" transmission service (drop pan and filter, then complete fluid change). The others are right it will cost somewhere less that $300. The old fluid didn't really look bad and when the pan was off the tranny it looked good (what we could see) inside. Now, jump forward about 25,000 miles. The old tranny stops functioning in 3 & 4. Granted I have no idea how the car was driven the first 47,000 miles but I am easy on my vehicles (I've got a '76 Pontiac GP with 350,000 miles on the original engine/transmission/rear end and a '67 Chevy step side pick up with over 450,000 miles on it, with a rebuild of the M3 tranny about 50,000 miles ago). With a new A4 in the Vette I can tell you one thing, I'll be servicing it more often than recomended by the manual. $300 for service vs. $2,600 for a new transmission, you be the judge. Dirty or burned fluid is death to an automatic transmission.

I own a transmission rebuilding shop, the part you have been told about (flushing the transmission, skip the filter, is hogwash) Your right to do both, if you want to do the best job you can. A little about what is going on in the trade, that one should know. A (transmission flush) Is not really as good as it sounds. It's really a fluid exchange, to a degree. A shop spends $3,500+ on a fluid exchanger,the fluid is picked up by the transmission pump from the pan, pushed into the torque converter where it mixes with old fluid, then it's pushed into the pressure cooler line, where it is captured in a reservoir, as the oil is captured, the same amount of (new)oil is pumped into the return cooler line, which feeds the gear-train and falls to the pan where it mixes with old oil, get my drift. 35 Qts later you might be (close) to having all new fluid. Transmission fluid if not overheated will last 100,000 miles, additive package in fluid will not, additive package is mainly used to keep seals soft, parts clean & oil from foaming, transmission filter is usually made from Dacron, Dacron hardens in five years of use, will tighten and plug because, transmissions throw metal, this is normal for a GM transmission.
Slightly darkened transmission fluid, is not bad fluid, it is normal. transmission fluids are not created equal, best bet is to buy from a company that drills for oil, they keep the creme of the crop for themselves, the rest is set up for bid. Many thoughts on this, but, if you run your car normally, to a little hard, change oil in transmission pan & filter every 20'000/25,000 miles. If you have a burnt oder to your fluid, or it no longer resembles the color of ATF, wouldn't be a bad idea to exchange it. If you have friction material in the pan (Black dust/flakes, change the filter only, reuse your burnt fluid and cross your fingers, an overhaul is in your future. I hope not to many typo's but got to go. Hope this helps, as for the filter needed I'd have to look it up, but if I remember I'll get back to you on Monday.
