I thought I had a pretty good grasp on ATF

[tehbry]

So I've read the ATF change for the B6 A4 quite a few times and I thought I had a pretty good grasp on it. You refill the trans while reading 32-34 C through vag and when it will no longer except more fluid while at that temperature range its full. So today I wanted to add 6oz of Auto RX to my trans to do some cleaning before I do my next ATF change. I went out and raised the car on ramps and stands and let the car cool for 2-3 hours because It was cranked and ran for a few minutes. I pull out the fill plug on the trans and fluid starts POURING out. I left the car alone for 2 more hours and tried again, same thing. At this point I decided to bust vagcom out and check the fluid temperature and it was only reading 23 C.

I was thinking that if the fluid temp was nowhere near 32-34 then NO FLUID would pour out of the fill plug. I'm guessing this means the shop that installed my torque converter added too much fluid?

Don't take this as gospel as I have a real transmission on mine but normally auto's are checked while the engine is running. At least my wife's BMW is.

[tehbry]

lol you have a real trans huh? You must be real proud of yourself

[tehbry]

Though I admit you may have a point in that I did not have the car running

Hey just so you know for next time when the trans is hot the fluid level will be at it's lowest. In not sure for the exact reason, but this is why they tell you to check at 32 because you can never get the correct amount of fluid in when it's cold.

Oh

Grr I hate not being able to edit on my phone. I meant to say: oh ok, so if I were to remove the fill plug after my 20 minute drive home there will be less fluid in the pan so none should spill out while I'm trying to add the Auto RX? See I was thinking if I removed the fill plug with the fluid pretty much as cold as possible would mean with the fluid thick it wouldn't drain out. So if I need to add the Auto RX with the fluid hot, should I do it with the car running?

You need to remove the FILL plug with the engine on (ie trans pump circulating). If you remove it with the engine off (trans fluid not circulating) then the level in the pan will exceed the fill line and leak out. Also, when you do your flush and start adding new fluid, once you get it full (fluid begins to drop out the fill port with the engine on) make sure you install the fill plugBEFORE you turn the engine off. If you turn the engine off before re-installing the fill plug a ton of your new fluid will gush out.

I hope you added more fluid or have not driven since accidentally draining fluid out....

[ADCS]

This is all covered in the factory fluid flush procedure so I suggest you read that before attempting again as there is more to it then just draining and re-filling...

You need to fill the fluid, cycle through gears, fill fluid, cycle through gears, etc.

Oh and ONLY use Audi fluid or ZF lifeguard fluid. Unless you want to do a trans swap in the near future.

Ok so do it with the engine hot and running. I only drained about 1/16th of a quart so I'm not concerned with the ride to work and back, the car drive fine. I collected the fluid and will re-add with the Auto RX.

[tehbry]

Wait actually im not sure if I should do it while below or above 34 C while running. Wouldn't removing the fill plug with the temp past 34 C cause the fluid to drain out the full plug?

[DiertyEuroSpec]

NO

Thanks, going to use that for a fluid change after I run the Auto RX for awhile. I noticed one of my trans pans bolts are stripped so not sure what I'm going to do about that but I'll figure something out. I believe they sell special sockets to remove stripped bolts.

Cut a slit in it and use a flat screw driver or a hammer and chisel to remove it
