HELP! Another transmission drain/fill failure-Not the green tube

[bcolins]

I got five more quarts of Volkswagen ATF and two new green plastic transmission fluid level determining tubes this morning. I had already drained the prior fluid change off and saved it into the original bottles so I had an empty transmission. I installed the new green transmission fluid level determining tube or just drain tube I think VW calls it, and firmly snugged it just with an Allen key by hand. I had only pumped in about 1 1/2 L when the fluid started coming back out the drain plug opening, the Van was not yet running. I installed the metal drain plug and crush washer just finger tight,… I decided to add all 4 quarts or liters. After pumping in the four bottles each bottle had about a quarter liter in the bottom so I consolidated those and pumped that in again not getting me quite to four liters because there was still some residual in the pump hose and about 300 mL in the bottom of the bottle. So I cracked the seal on my fifth bottle, added The 300 was still in the bottom of the fourth bottle and then another 250 mL for good measure. I let the van cool down until the transmission temperature was back down to about 100°F, and started the van up and cycled it through Park, reverse, neutral, drive, three, two, one, then back up to Park then back down to one and back up to park did that three or four times holding each selected gear for about 10 seconds. And then put it back in park with engine running and went back out underneath the van and checked the pan temperature I was right at 110° I placed a clean bottle under the drain plug removed the drain plug hoping that I would just get a little dribble and then a few drips and be done but yet again as before I got a stream of transmission fluid coming down through the green tube as if the green tube was not there I quickly filled up the majority of that liter bottle and at about 3/4 of a liter draining out I decided it was time to put the metal drain plug back in. There is something wrong here and I can’t for the life of me figure it out I’ve now spent $300 on fluid I changed it a few months back 2 to 3000 miles ago and it went exactly as it should have and then earlier this week was the first instance of it doing this constantly streaming fluid as if the green straw was not in place. I’m now thinking I should just put in 4 L plus an additional 250 mL torque down the drain plug and go as I am tentatively leaving for Colorado in the morning. Hoping for some input here this evening so I can put this issue to rest and feel comfortable on my trip heading out tomorrow. The first leg of my trip tomorrow is only about 100 miles to a friends home 🏡 in an area lake to celebrate the Fourth of July and then leaving from there the following day or two later to head to Las Vegas New Mexico and then up to Angelfire and o oko then up to Paonia Colorado for a BMW motorcycle rally. Please share your thoughts with what’s going on with my transmission here if you think I’m going to grenade this thing with 4 L plus an additional 250 mL of fluid in place.

Well, fook.

Are you sure it’s draining down the tube and not leaking from it being poorly seated ? Under time pressure I would take the pan off , make sure the tube is in right, and then refill to drip again.

You easily can get 4 liters stuck in the TC and rest of trams so filling by reference is probably error prone

Just a coffee filter strain to get road Chunkies out. It isn’t a neuron , the filter will catch anything small.

Sorry I didn’t catch you this morning , had to weld two exhausts fir this week on my day off

Your paint strainer , even single use is fine. You just want to catch the road dirt that inevitably falls of the car into your oil pan when you capture the oil

I’ll pm you my number for the T4 support group, appreciate your content here

Mystery solved!!! When the transmission oil pan is drained but not removed from the engine, it is not actually fully drained,…there is still somewhere between a quart and a quart and a half in the pan. On my first drain and fill a few months back I replace the transmission filter so of course I dropped the pan and replaced the gasket and the filter etc. This time I only drained and refilled not realizing there was a quart to a quart and a half already in the pan so when I was adding The 4 L plus an additional 250 mL I actually had 5 to 5 1/2 or more liters in the transmission oil pan at that point. So this entire snafu amounted to nothing more than me not being aware that the transmission oil pan held a significant quantity of oil even when it was fully “drained” 😡

Didn’t realize you weren’t dropping the pan. Assumed it’s a given with a fluid change. Filters are cheap. Worth changing when you swap the fluid.

FFS, where can I find this tube? Doing a a full-van fluids change and mine was broken and half-assed together with some chopped off tubing. None of my usual sources seem to carry it by any name. TIA!
