Your logic is sound - a whine at startup is low fluid.So I did a pan drop and fluid fill, not flush two weeks ago. Fluid instantly started gushing out when I opened the fill plug with a completely cooled transmission that sat overnight. So I’m thinking it was due to being overfilled and becoming foamy once it reached operating temp and hence the pump starts to whine. Low fluid, I would have expected it at startup, clogged filter medium, same thing. So far, two weeks in with the correct fluid level and new filter, zero whine. Now I’m worried it wasn’t overfilled with trans fluid from the factory, but some other residual fluid. Will find out when the Blackstone report comes back.
Perfectly normal in a cold transmission for 2.5 to 3 quarts to come out when removing the fill plug on the side. This is the fluid that has drained out of the torque converter. Then there is about 4 quarts remaining in the pan below the fill port.So I did a pan drop and fluid fill, not flush two weeks ago.

So what is the MILAGE on the oil you sent to Blackstone? I hope you post the results.Thanks guys, went through the full procedure. I’ve done it 3 times before on my WK2 with the ZF built 8 speed. The first time I cracked that one open, nothing came out. Went through the procedure of gears, running, etc, but it was still cold (under the temp window for checking the level 80-120), so did not expect it to gush out when I cracked it open.
33,500… definitely will report back. I’m curious if it’ll show glycol too.So what is the MILAGE on the oil you sent to Blackstone? I hope you post the results.
Did the oil have a good stir before bottling the sample?33,500… definitely will report back. I’m curious if it’ll show glycol too.
