B7 A4 Tiptronic - ATF Replacement

[Tiptronichris]

I wanted to thank member fly300kts for this thread but the tread is closed:

https://www.audizine.com/forum/showthread.php/414061-B7-A4-Tiptronic-ATF-Replacement

I also wanted to share a couple tricks. See pic. Cut the end of the OUT hose Harbor Freight $9 pump on an angle. This helps the hose feed through the filler "hat". Securing the pump to something that doesn't move makes all the difference you only have two hands like myself. I used a liqueur bottle for the rear diff oil change, and a gallon milk jug for the transmission. Of course it doesn't matter what clean container is used, the important idea is to secure the "IN" hose so it can't move from the bottom of the container.

Definitely worth the trouble to change the filter and oil. Made noticeable difference on my 180k car. $600+ at the dealer would hit the bill fold. Also, I decided to just put the pan back on with the factory seal. It was still securely attached to the pan and the two "fin" seal locked great. No leaks.

Good tricks! I would just recommend that anyone doing this always change the trans pan gasket when doing this job. It would really suck to have to re-do this due to a leak developing.

When I did mine, I used a small drill pump. $15 and is much, much faster. Filled it before it reached 40°c once. Worked great.204147

1: Paper gaskets suck.
2: If the pan leaked I though hell with it. I will flush it again. Still save hundreds.
3: If you see the stock gasket its a very well engineered piece with over-molded seal on a metal substrate. There is no risk of over or under tightening.
4: With the stock gasket, the gasket gap is factory spec, oil level correct.

I was attentive about the 40C trans temp limit. On a cold drive train in park, it would take quite a bit of time with the engine running to get above 40C in my experience.

Did you have any RPM fluctuation with a cold gearbox before you changed the oil? What makes it "definetly worth it" to change the oil?

Did you have any RPM fluctuation with a cold gearbox before you changed the oil? What makes it "definetly worth it" to change the oil?I had bad "hunting" issue. And has gotten much better. Id say its 90% better. I did the filter, fluid, gasket, all ZF brand. Then did another drain/fill (3 liters) to get more fluid swapped. I still have to do the pressure reset adaptation, or whatever its called. But its much better. Plus its just good to do, lol. Did mine at like 175k miles, so it was due.

Looking to do this soon with my TIP @ 125k, thanks for the tips!

I also wanted to ask about doing the trans fluid with Redline D6 instead of OE stuff since it's slightly cheaper... Redline is known as a great brand on tons of different makes and models, and I'm wondering if anyone here has used Redline fluid instead of ZF LG6/8. On their product page it claims to meet ZF fluid specifications. There's also a shop really close to me that has this stuff in stock straight off the shelf.

If the trans was out, and totally drained, I'd prob try the aftermarket stuff. But I just went with LG8, cuz I knew 100% I wouldn't have an issue. Cost me $200 for all ZF stuff.

Link: https://www.redlineoil.com/d6-atfIf you're in the US, I've heard this place is the cheapest for genuine ZF gear. LG8 is only $23/quart: https://www.thectsc.com/catalog/8-speed-62.html
At that price, why risk it with aftermarket fluid.

FWIW I used the Mopar fluid, same fluid, because it was a lot cheaper than Audi or ZF branded stuff up here in Canada-stan.

Like JayZ, my rpm hunting/fluctuating mostly went away too......but, in my case at least, now it's coming back with the dropping seasonal temperatures. Just adding that circumstancial grain of salt on the question of whether to do the service for that reason. [emoji12] Glad I did it though, the old fluid was really dirty and there have been no adverse effects in tranny performance.

Found this video series recently, in case anyone's interested. This guy is awesome.

The cold cruise RPM flutter didn't go away after my ATF was changed twice. When you drop the pan about 40% of the ATF comes out. So it's not like a flush. I heard you shouldn't do flushes on transmissions with really old fluid. I noticed cleaner shifts with the fresh fluid. But be sure to use VIN specific OEM ATF.

I also changed the filter and the magnet was cleaned. May as well do this if you drop the pan.

[Cyrik]

I heard you shouldn't do flushes on transmissions with really old fluid.

It's a myth, some claim that after fluid has been sitting inside the trans for a long time, the fluid essentially is what holds the trans together and changing the fluid will take chunks of metal/bits of the trans with it.

Yes, it could be a risk however from what I've seen in this thread alone, people here are changing their fluid at 150K+ (first time changing it I assume) without issue.

Only time I wouldn't change the trans fluid is if you're already having MAJOR issues with your trans to begin with (I'm talking about trans codes + grinding sounds, etc. when shifting for example) and at that point you're already living on borrowed time.

I still call this a myth in the auto industry. I'm going to change my virgin 14 year old fluid here soon, so I'll let everyone know how it goes.

[Cyrik]

But be sure to use VIN specific OEM ATF.

ZF Lifeguard 8 is compatible with ZF 6/6+ and applies to all Tiptronic transmissions for the B7.

[beefski]

Amsoil also makes applicable trans fluid. Available online

Cuz new fluid could make it worse. Cuz if its slipping, the clutch material floating around in the fluid, could be helping it grab. But if no slipping issue, new fluid is only a plus,

This myth is something that has been on my mind a lot with my car. (at 175k factory fluid from what I can tell) But between this tread and the DYI It looks like I'll be changing my fluid some time in the next few months. This is my 1st auto trans in an Audi, so still a lot to learn for me.

I have also been researching the vin specific fluid, Not saying this is wrong at all, but what tells one its compatible? Straight from ZF? A good Audi shop? triable knowledge? Maybe I missed something in the DIY?

This makes me feel even more inclined to change my fluid as I have 0 slip, as far as I can tell. Now that I've been DD the car for some time, I have noticed a small bump from 4-3 and 2-3 but its not every time.


Lots of good info here.

07-08 will always have the newer software, requiring LG8. If you have an 05.5-06, then good to check your software(vcds, obdeleven) to see what you need. Earlier software using LG6, if updated, LG8. I bought everything ZF brand from FCP for about $200. Then a few weeks later bought a few more liters of fluid, did a drain and fill, and sent back what came out for full refund. Wanted to get more fluid swapped. I used justvunder 5 liters the first time(bought 6) with pan drop and filter. Second time I just drained and filled , and only took 3 liters. Was even on sale at the time on FCP for $18/liter. Unfortunately, just looked and its $23 now. But still worth getting there if ya think ya may wanna swap it again. Good luck.

(1) On my door sticker, it indicates the car was built in 06, and sold at the end of the year as an 07 Soo LG8? I'll check the vin.

(2) You sent them the used fluid and they gave you a full refund?

Yea FCP is great
They'll Lifetime warranty basically everything short of aerosol spray cans and additives.

Yes sir, FCP is tip top!
I got a lot of parts from them for my B5, and it was always a good experience, unlike ECS. But I did not think they would refund used trans fluid. But that's cool.

Yes I meant to re-iterate this, haven't gotten around to clarifying/rephrasing what I said about all B7 Tips taking LG8.

Most B7's running around AFAIK have the updated software at this point, but I totally could be wrong about this.

If you're not sure about the VIN split for what type of fluid your car takes, open your hood and look at the valve cover. Is it black? use Lifeguard 8. Is it silver/metal? use Lifeguard 6 unless your trans software has been updated (in which case like Jayz said use LG8) (all BWT engines with a TIP are newer software)

Soooooooo essentially free fluid at the end of the day... Interesting...

I knew you could return used oil and shit to FCP but it's not typically worth it since shipping costs are a thing. I'll DEFINITELY look into this now... 😈

[emoji48]Well shipping isn't bad for me, I'm in PA. Cost me $20 for oil change. Of like last week, lol change and CF replacement, same cost. And yes, second round of fluid was free(cost of shipping). Ordered 4 liters, but only got 3 out from simple drain. So got refund for 3($60).

I'm driving a 3.2, not sure if the valve cover is a tell tail sign for me?

The engine code (BKH) will defiantly not line up, but thanks for the info.

Mine probably is based off your date and what jayz saying. My car was built in October 06, but I'll confirm and have something for temp monitoring.

I just wanted a month to make the correct response. The "haunting" "hunting" is all but gone. Very well time/money spent saving the tranny/sanity. I used Redline BTW.

Hi, I recently bought the fill pump from Harbor Freight, I was wondering how much fluid did you loose asking because ATF fluid is expensive. Should I buy one more quart than what it calls for ?

Hi, I recently bought the fill pump from Harbor Freight, I was wondering how much fluid did you loose asking because ATF fluid is expensive. Should I buy one more quart than what it calls for ?Mine took about 4.5 liters, I didn't spill much cuz I used a drill pump. Much faster, so got it filled in 1 shot, before it got to temp. So 6 liters is a safe bet, in case your job gets a bit messy. The drill pump was also much easier, just pull the trigger, lol.

Another question about the required amount of fluid... A friend of mine has a shop and they have a flushing machine (vaccum?), will this remove more fluid then a pump like those mentioned above? Totoal capacity of the gearbox is 9L?
