Trans whine 2000 miles after trans fluid and filter change

[mooll]

i know what you're thinking. "you're fluid is low "
it's not i checked it yesterday properly cause i was worried and and it is not low, its perfectly topped off.
filter and fluid was changed twice in October '16 roughly 2000 miles ago.
i know its coming from the trans i know that and it's not any different when hot or cold. I really notice it cause i almost always manual shift from 2 to 3 to 4th gear around town at low and high rpms, and it's loudest in 4th gear, but it's the same whine.
no TQ shudder at all.
also, this has been a prob for a WHILE but it hunts for gears when coasting at idle speed. like it'll go from say idk 800 rpms to 6 then back to 8 then to 6 then 8. they are quick changes in RPM , however this only happens in D.
i've also noticed it seems like there is ever so slightly less power to trans ( not less power per se, but something just feels off compared to just even one week ago, this is a NEW issue ) AND my shifts are slow sometimes when coasting say at 25 and i want to get to 65 to merge, really gotta push that pedal down quick ( gotta push it down more than i had to before this issue, this is NOT normal , its like my trans is slower now and less responsive ) to get into a normal higher gear to accelerate say when merging and then release it back up. so almost every time NOW i have to really push the gas down farther ( when accelerating in D rapidly like when merging onto highway ) to get it to go into a higher gear/shift properly RIGHT away, but it does shift and not in a concerning way. no clunks or slips. one more thing--when manual shifting from D to 4 it really likes to grab 4 hard--it's a strong jerk--ALMOST a clunk. been this way since this trans was installed in OCT '16 but i can honestly say now that this particular part of the issue HAS gotten worse, but not much.
Am i explaining this good enough ? lmk if i can provide any more info
TIA people.

Did you use a Filtran filter? Supposedly if you don't, it will whine. And what fluid was used?

Ive only used the ZF fluid and the filtran and haven't had issues. For clunking you could also check transmission mounts for wear.

+1 on Filtran filter. If you use another brand, it is very likely that the filter is collapsing in on itself and thus causing the whine.

[Timm]

The noise is very likely the filter - but - you also have torque-converter lock-up problems. Those gear changes you feel at low revs are not gear changes - it is: the torque converter locks, the revs drop, the pressure to the clutch drops (due to the drop in revs) - the clutch opens again - repeat at around 2-second intervals. More info here:

" The other problem that slowly got worse was a regular drop in revs when cruising, especially in 5th gear at 60 MPH. The drop in revs was barely noticeable but could just be seen on the tachometer and was very regularly occurring every two seconds."

OK ppl thank you.
it is FILTRAN oem bmw filter AND o ring and i used valvoline maxlife fluid--nothing wrong with that combination.
damn im starting to think it may be the TQ , sucks i just had this trans out 2 months ago...

also timm i already have a tube or 2 of dr tranny fix shudder lube gaurd stuff in there, so it must b bad.

[Timm]

Yes, sounds like it's a goner!

[mooll]

so if fluid and filter are good then its the TC that's whining, too ?
damn tho i shoulda replaced the TC with new when i had the trans replaced 2 months ago.
it's OK/safe to drive with A bad/ going bad TC ??

[Timm]

Yes, the torque converter itself is working fine - it's just the lock-up clutch that has failed - the rest of it is bent bits of tin and fluid!

[mooll]

Are those bits on metal and such getting in my fluid ?? or staying in the TC

where can i get a new tc for a decent price ? has any one heard of DACCO ?
i have a used one but idk if that'd be worth putting in. do these fail often ? the one i have has 122k on it.

dude srsly ...?
you NEVER read the full thread. clearly you didn't even read the first post, or ANY posts and just felt like commenting your opinion, which has already been proven NOT to be the issue...
but thanks tho guy BIG help u always are when u comment on one of my threads.

out of curiosity, How did you check you fluid level? IIRC there is a special procedure to check this. Just trying to make sure it was checked properly, you can get all of these symptoms from low fluid. Don't jump down my throat like the other guy, we're just trying to help. It's important to verify that fluid level was checked properly, instead of "it's perfectly topped off" before condemning the TC.

[mooll]

i followed the correct procedure as i have done my trans filter a couple times before

[Jimmy E34]

I can't provide any helpful information apart from that I changed the filter (using Filtran filter) and correct amount of fluid and now have a transmission whine when the gearbox changes gears when it is cold too. There was no noise evident before the filter change.

DIRECTLY after ? in my case it waited about 2k miles to appear

[mooll]

^?
also yeah to make it clear the procedure was followed correctly, as i know the bmw proper way to fill or top off the trans since i have done it a few times before. there's only one correct way to do it, people. i even used a infrared thermometer to be sure it was properly filled at the right temp, and even checked the fluid when cold to be 100%

Lol that was not me jumping down his throat, it's just his ignorance is not wanted here. but if he wanted to actuALLy read the post and lend help, sure, that'd be great...

My Bad , I did not read the full tread...Sometimes theres a 10-20 pages of replies...I never read thru all that..
BTW how do u know theres bent pieces of the TC Lock convertor?

- - - Updated - - -

TC convertors are $250-400 new ..I would suggest Dr Tranny shudder fix but apparently your TC is beyond repair..Good Luck m8

[mooll]

thanks...but i mean like i said in post nbr 5-- there's already a tube or 2 of that shtuff in there now and obviously things are the way they are still with it mixed in there. i mean i haven't really condemned the converter yet , i'm thinking maybe there's a possible issue with the filter or o ring ? would be a shame if so that's a lot of work to do again so soon, especially doing it on just ramps and stands.

im looking for a good brand TC if some one could chime in on that

[mooll]

tmrw I'm gonna be replacing both the original tran lines for first time , filter/o ring and pan gasket again for the third time (thx fcp) to see if that solves the whine and other weird issues. we'll see...

[kouks]

If you still are considering a TC, go to Erickson Industries in Connecticut, google their webpage and call them. Authorized ZF rebuild facility, TC is about $250 with core turn in, and its a real ZF TC.

[mooll]

as to how / why the oem filtran filter failed in such short time(2k miles)... idk. never heard of this before. anyway, i put the new cooler lines on and the new filter/oring and there's no whine rn but the "bucking" is still there.
i hope i don't have to crawl under this thing again at least until spring lol
