Filling 6L80E

[gaz05]

This shows the position of the sump level plug and filler bung (on drivers side)



This is filler plug (driver side)



Removed (pull up top part then removed plug)



I used a syphon and Dextron to top up, replaced the bung. Ran car to op temp and cycled through gears, remove sump level plug on level ground and wait til flow ceases to a constant drip and reinstall sump plug. If no flow add more fluid!

Its a shame the VE oil pan doesnt look like that, would not have as many dramas........ that looks like a Corvette one.

Hope this picture is attached. This is a standard VE pan and filter, if you look at the fill level.. the top of that tube, it barely covers the filter, if you look closely those two little feet on top of the filter sit against the valve body, as you can see the valve body intrudes into the pan area leaving very little volume for oil. As soon as you accelerate hard the oil is gone, what there is of it!! Thats why overfilling them helps a bit. It really is a major problem with A6s.

This what I have done, made one out of two...25mm deeper.

[gaz05]

This is what you have to do.... deepen the pan, baffles..make them out of the other pan floor that you cut up and add 25mm to fill tube, machine a 25mm extension for the filter pick up tube.. all good, holds another couple of litres as well.

Thought I had a pic of the spacer to extend the pickup tube, cant find it at the moment, also the little right angle feet on top of the filter are about 10mm high, you have to make them 25mm taller also so it rests against the valve body like the factory arrangement, I just used the material out of the old pan to make them and you rivet them to the existing feet on top of the filter. Once you do this the box can be tuned properly, mine works like any turbo box, makes a big difference when you keep the oil up to them.. hope this helps.

The first pic shown is a corvette pan, for those having issues for DD cars I recommend that you get hold of a C6 corvette pan and pickup it will help a big deal. Also when filling the tran have it up to temp as atf has a very high expansion rate- undo the level check plug it will spill some oil as the tube is containing oil from it splashing in the pan let it settle, top it up till it spills over, cap it off then put another litre in the thing.

This is a very important fix, infact its how we got gaz's car into the tens, Difference is night and day shifts like a full manual turbo 400, but only difference is, its even better, really shows how good the A6 really is when they have oil. A good box was designed and built and a not so bright engineer put a shit pan on the VE for ground clearance. Even stock cars have problems with flaring thats just from the oil sloshing around in the pan. So sucking air is a problem. Aerated oil, is a major problem it is probably worse as it will ensure a long slow death of the tranny.

We have offered to help out those having troubles with some good info on how to tune the a6 correctly once it has oil pressure without the box to require any learning so you can flash it at the track without it flaring and relearning etc.

Overfilling the pan will not fix the issue in a race situation. Oil moves the fastest from the initial G force on the launch. It heads to the rear of the pan and thats why so many a6 cars et and half mph avg but deepend mph is good because once at speed the oil starts to level out. By then though the whole sump is aerated and its game over. It has to be done properly and I am sure if you do this mod before anyother , the a6s true potential will be shown.

Hymey, I don't run my car on the track but this is an extremely interesting post. Can you give a rough estimate of how much ground clearance is reduced by fitting the different sump?

[etrocket]

Also where can we get these sumps

Its 25mm lower, not really a problem, its no lower then the engine sump, the collectors on the pipes is the lowest point on mine. I will take a pic under the car tomorrow and post it.

I used 2 VE pans, about $130 each at your local GM parts outlet, I priced a Corvette one before I made mine... (still would have to baffle it too) $560 plus freight from the US.

Gaz - Are you able to take a photo of your pan. Can't picture what you have done. Are what trans cooler are you using

?????? I have posted pics of the standard VE pan and the modified one that is on my car earlier in this thread. I dont use a trans cooler Rocket.

This is interesting!

Would be worthwhile you guys making up a few more and I am sure people on here would grab them from you! I know I would be tempted at the right price!
