Best Audi A8 Transmission Service

Background
Changing the transmission fluid in addition to filter is likely the MOST IMPORTANT service that you lot tin ship away perform on your A8. The transmission has metallic element vesture components. Once these wear, the filter clogs upward in addition to the stone oil is degraded over time. This starves the hydraulic catch of oil, peculiarly on mutual frigidness start ups in addition to causes the catch to cavitate. This is the squealing noise that tin ship away live on heard. This tin ship away elbow grease long term harm to the transmission.

Audi states the automatic transmission fluid (ATF) is a lifetime fluid. This is non true. It is recommend to alter the fluid in addition to filter every 25,000 to 40,000 miles. This tin ship away salve over $8,000 for a rebuilt transmission.

Parts Needed

• 01L-325-429-A Filter (see banker's complaint below)
• 01L-325-443 Filter to Transmission Gasket/O-Ring
• 01L-321-371 Pan Gasket
• 01V-321-379 Fill Plug Sealing Washer
• G-052-162-A2 ATF Fluid (have 8-9 quarts on hand, you lot powerfulness utilisation a footling less), utilisation ONLY Audi fluid

NOTE: 01L-325-429 is the filter run position out for model yr 1997 A8's that came amongst a type DPZ transmission amongst a series position out of 001891 or less.

01L-325-429-A is for all 1997 A8's amongst DPZ transmissions amongst series numbers greater than 001892, DSM type transmissions in addition to DTE transmissions. The DTE transmission was supplied on afterward 97's in addition to all 98-03 A8's.

The transmission nameplate tin ship away live on constitute on the bottom of the transmission only frontwards of the pan.



Location of nameplate. Nameplate data: 1) Transmission series position out 2)Transmission series position out 3)Transmission identification (all volition live on 5HP-24) 4)Code letters



Here is the kit you lot volition need. Buy it from Wendy Hager past times emailing her. She utilisation to live on a parts director at an Audi dealer, similar a shot on her own. Very knowledgeable person!

She sells it for $23.95 summation transportation for the filter, pan gasket in addition to drain plug o-ring.
Dealer listing price: $80.64.

Special Tools Required
There are a few special tools required to consummate the job. There are ii pan torx screws inwards a higher identify the right mitt catalytic converter that volition demand to live on eased out amongst a modified torx wrench. You volition also demand a breaker bar (2' pipage to lucifer over the allen wrench) most probable to take away the create total plug, in addition to a catch to acquire the novel fluid into the transmission.

• Torx T-27 bit, it volition convey to live on reason downward
• Socketed Torx T-27
• Screwdriver type Torx T-25
• "L" shaped 17mm allen wrench
• Marine Outboard Pump amongst Copper Tube Installed detect it whatsoever marine shop equally Boat United States or West Marine for inboard/outboard motors
• Duct record to direct keep marine catch stone oil describe inwards identify during stone oil create total

With these tools, you lot volition non convey to drib the exhaust to service the transmission.



Marine outboard pump. Purchase it at whatsoever marine store. Modify it past times removing the threaded insert that screws into the outboard drive, in addition to install a copper pipe. See pictures below for modified pump. They cost nigh $5.00.



Purchase socketed in addition to flake type T-27. You'll convey to grind downward the dorsum side of the flake type to arrive brusk plenty to take away the ii torx screws inwards a higher identify the right mitt catalytic converter.

Procedure
The Bentley service manual for the A8 states the physical care for equally follows, sounds slowly enough:

1. Open drain plug in addition to allow fluid drain.
2. Remove transmission pan bolts in addition to take away pan.
3. Remove filter (screen) bolts in addition to take away erstwhile filter.
4. Install novel filter.
5. Install transmission pan.
6. Remove create total plug in addition to add together novel fluid.

Of course, the physical care for is a footling to a greater extent than complicated than that. With the aid of the friendly people on AudiWorld, I was able to produce all the work.



The victim ready for work. Note that the automobile should live on level
for this procedure. If not, you lot can't properly create total the transmission. Put the automobile upward on 4 jack stands if you lot don't convey your ain lift. See moving-picture present at exceed of this physical care for for jacking points. Use jackstands at the rocker panel jack points to back upward the car. It must live on flat to perform this procedure.



These are the parts you lot need: pan gasket, novel screen, in addition to super special VW/Audi transmission fluid (at $12 -15/quart, you lot should purchase 8 quarts). Remember to also purchase novel vanquish washers for the drain in addition to create total plugs (I didn't in addition to if the originals leak I volition live on real mad).



This is the transmission pan. The minor bolt is the drain, the large i is the fill. The bolts are Torx bolts, size T-27. Why Torx in addition to non Allen? Why T-27 instead of the to a greater extent than mutual T-25 or T-30? We must all brand sacrifices to the Audi Gods.

The create total plug is a 17mm Allen. Make certain you lot tin ship away take away the create total plug before you lot opened upward the drain plug. You don't desire to drain the fluid, in addition to then detect that you lot can't create total it! I tried using ii 17mm nuts welded to a bolt amongst a 17mm head. No good. The create total plug took a lot of torque to loosen. I had to purchase a 17mm L shaped allen for $9.00. I position a 2' pipage on the terminate in addition to it came right out.



Different shot of the transmission pan. Of course, zilch tin ship away live on easy. Note that ii bolts are obstructed past times the catalytic converter. You could take away the exhaust, but that would live on a existent pain. Instead, purchase a Torx T-27 flake from Sears. Grind off nigh 1/4" off the dorsum side. Lock it into a vise grips, in addition to you lot tin ship away utilisation that to loosen the ii bolts. I also recommend you lot convey a socketed T-27, in addition to a screwdriver type T-25. You tin ship away utilisation the T-25 to take away the ii obstructed bolts. The smaller tool allows you lot a amend angle into the bolt. Be careful to non harm the bolt caput likewise much.




Ground downward T-27 flake inwards vice grips. This volition allow you lot to get
the ii hidden T-27 screws out without dropping the exhaust.



One to a greater extent than shot of difficult to acquire Torx screws, they are on the right mitt side of the pan.


You demand a socketed T-27 to torque the bolts when you lot re-install them. It's also a lot faster to utilisation the socketed tool than to position the flake into a 1/4" socket. The flake volition autumn out in addition to you lot volition waste matter a lot of fourth dimension crawling around the flooring trying to detect it.

Make certain you lot tin ship away loosen the ii bolts earlier you lot drain the fluid.



Transmission fluid draining. Be prepared for nigh 6-7 quarts to drain. Note that the Audi fluid is non crimson similar every other transmission fluid. It's class of yellowish green. Mine was inwards much amend status than I anticipated. It was even hence clear, non burnt in addition to did non scent rancid or overheated.

Note the ii obstructed bolts inwards the bottom left.

I was surprised that when I removed the create total plug, a lot of fluid came pouring out. Fortunately I had the drain pan positioned. I learned that when the engine is running, a few quarts of fluid acquire sucked out of the pan into the transmission.



The fluid is drained, in addition to the pan is off! There is a adept amount of sediment inwards the bottom of the pan. The 4 minor rectangles are magnets to collect whatsoever steel particles. Mine had some sludge on them, but it appeared to live on normal wear.

The parts director didn't mean value it was necessary to alter the fluid, equally Audi describes it equally "lifetime". Considering the amount of sediment in addition to sludge present, I disagree. audipages.com recommends changing the fluid every 25,000-40,000 miles.



The filter is even hence bolted to the transmission amongst ii bolts. Remove them in addition to it comes down. Note that in that location is a prophylactic o band on the output of the filter. Note that those ii bolts are dissimilar than the trans-pan bolts (shallower head).



The filter has been removed. Here you lot tin ship away come across that it is also covered inwards sediment.



New filter in addition to erstwhile filter. Which would you lot rather convey inwards your car?



Nice construct clean plan. I used stone oil eater type stuff, in addition to then some rags. Follow amongst a launder of brake clean, in addition to goal amongst newspaper towel.



When installing novel filter, brand certain the filter to transmission gasket/o-ring is inwards place!



Clean pan, drain bolt installed, gasket placed. I utilisation a dab of vaseline to direct keep the gasket inwards seat until it tin ship away live on bolted inwards place.

Position the pan in addition to bolt it inwards amongst iii bolts. Make certain the gasket is properly positioned in addition to insert the balance of the bolts finger tight. Then utilisation a cross type designing to tighten each bolt to 7-9 ft. lbs. You won't live on able to torque the ii bolts inwards a higher identify the catalytic converter, hence only brand those snug.

Filling the Transmission
This is the MOST CRITICAL run of this procedure. Now came the difficult part, filling the fluid.

You volition demand to brand a catch to catch the fluid into the transmission. The pan has a stand upward pipage for the create total line, this is how the right transmission fluid flat is determined. Purchase a marine stone oil catch (one to create total an inboard/outboard drive) from a local marine store, in addition to become to the hardware shop in addition to purchase a minor slice of copper tubing. Insert the copper tubbing into the terminate of the catch (remove the plumbing equipment that comes amongst the pump) in addition to curvature it slightly hence it tin ship away catch upward in addition to over the stand upward pipe. See pictures below.



Marine catch amongst copper subway scheme fitted to catch stone oil into the transmission.



How pan stand upward pipage plant to command level. Fluid is pumped into the transmission pan until the flat reaches the exceed of the stand upward pipe. It in addition to then overflows out of the transmission. This flat is higher when the automobile is non running versus running due to the hydraulic catch pumping fluid through the transmission.

The entire physical care for is documented below from start to goal for repose of discussion.

Good view to position the automobile upward on lifts, drain the fluid, drib the pan in addition to unbolt the filter at night.

Let is sit down overnight, it volition drain all nighttime long.

The automobile must live on at ambient (cool) temperature earlier filling the transmission! This requires the automobile to sit down overnight to completely cool off.

Install the novel filter the side past times side morn (don't forget the filter to transmission o-ring/gasket), bolt the pan up. Fill the pan amongst equally much fluid equally you lot tin ship away amongst the automobile off (until it starts flowing out of the standpipe, what I telephone phone the create total hole).

Start the car. Right away it volition start taking more, give it nigh 20-30 seconds to start pumping fluid through the tranny.

Keep filling until it overflows. Should live on 2-3 to a greater extent than quarts (initial create total nigh 4 quarts).

Have somebody run through all the gears for thirty seconds each (with the brake on), when doing reverse, the fluid volition menses out, allow it, in addition to then become through N,D,4,3,2 thirty seconds each. This is nigh 10-15 minutes into the create total after the automobile started.

Let the automobile run some other 2 minutes, in addition to then run it through all gears for thirty seconds again, produce Reverse for a shorter fourth dimension because it volition squirt out.

Keep filling hence it has a slight overflow at all times.

If you lot convey the Ross-Tech software, monitor ATF fluid temperature on grouping position out 4, nether mensuration blocks, transmission module. The temperature of the ATF fluid during this physical care for should live on 30-45 C. If the engine is operated for nigh xv minutes from ambient temperature, it volition accomplish somewhere around 45 C at the terminate of the xv minutes. This is why the automobile must live on cooled overnight. If you lot produce non convey the software, only ensure it was cooled overnight. It is non absolutely critical to mensurate ATF fluid temperature. However, you lot CANNOT produce this if the transmission is non at ambient at the get-go of the fill.

You'll demand a total of 8 quarts of ATF on hand, I would convey nine in that location inwards representative you lot tumble one...you only might.

BEFORE TURNING OFF THE CAR, position the stand upward pipage plug inwards (fill plug). Turn off car. The physical care for is complete. Test drive it for a few days, if anything does non audio correct, depository fiscal establishment check flat again. However, your transmission should live on operating significantly smoother. There is no demand to depository fiscal establishment check the flat in i lawsuit to a greater extent than if in that location is zilch incorrect amongst the transmission.

Other Transmission Fluid Changing Pictures
Here is some other transmission fluid changing success story. This automobile went into "limp home" vogue (PRND432 low-cal upward on the dash) in addition to the possessor view he needed a novel transmission. We ended upward checking the fluid level, in addition to constitute it was INCREDIBLY DIRTY! The side past times side weekend, the fluid was changed.

Below are pictures of the transmission pan magnets, come across they are completely filled amongst metallic element particles. This are genuinely real fine particles, but hold off similar something bigger, it's only the magnets doing that. Check the stone oil out, it was completely dark (new fluid is essentially clear) in addition to had metallic element particles throughout the fluid.

After changing the fluid in addition to filter, the transmission ran real smooth, in addition to the possessor had i to a greater extent than "limp home" vogue inwards the side past times side vi months (it was reset past times turning the automobile on in addition to off). The transmission is even hence operating only fine. The possessor volition perform some other fluid in addition to filter alter vi months after this change.
