stamar, thank you for the advice, I plan on doing it.

I am buying some engine oil filter magnets this week too, Ill stick a couple on the tranny pan as well.

nice actually link me to those. I am about to do this job myself on my toyota.

I was going to say especially on the pan dropping change, use a huge magnet.

I totally forgot to say that but you already know the deal.

My maintenance guy told me that, on the same car i did this on that hadnt had a trans change in 100k miles.

alright so what your saying is do partial flushes and work my way to the full flush? BTW still nub I'm learning my fluids still whats dx 6?

okk dexron 6 is gms newest trans fluiid.

Like when your trans came out I think it took dexron ii

ok heres the real kicker, dexron 2 isnt called dexron 2 anymore its called multi vehicle formula

dexron 3 is supposed to be backward compatible with dexron 2 but it is much thicker. so ( for toyotas) its the wrong stuff and gums stuff up and also doesnt last long. Its the mass produced crap version for all cars or dexron 2.

( zf might be the same might not look that up on your own)

so dexron 4 was kinda rare.... i never saw dexron 5 for sale.

but then dexron 6 came out like gangbusters.

they are all backwards compatible but dexron 6 also:

Is semi synthetic ( enough to be called synthetic fluid) it also has trans additive to it like that trans tune stuff

why Im so stoked on it is price if you get the walmart stuff its 4.27 a quart.

because its newer on the market theres not a long list of personal use but ill give you 2

Ive used it twice on toyota aisin auto trans and it magically transformed them.

but because its made for more modern vehicles I dont recomend putting all 10 quarts in right away because its too detergent. once you start putting it in commit to draining 3 seperate times.

need to get the gunk out that its freeing.

I have heard people just putting 10 quarts in on toyota trans and having no problems at all I just dont recomend doing that I dont do that.

Sounds just like the glove compartments on every e34 I have ever owned.

[5Toes]

WOW. Just went through my e34's glovebox and found lots of goodies!

a 1991 BMW dealership map
service manual
my radio code book
"DiamondTel" phone manual
Owner's Manual to car
Original BMW radio instructions

and a few other bits... all in pristine shape! Some of the plastic covers though have absorbed ink from papers that were on top of them :(

thats what I thought theres a drain bolt.


k heres what to do exactly for a neglected trans.


Drain and fill. drive shrt distance 30-100 miles. like 2.5 qt

drop pan replace filter and gasket. this gets like 4 qt

drain and fill again next oil change 2.5 or do a full passive flush. if you alrady took out 6.5 qts in the last 3k miles youre good to get it all 10 qt. With dx 6 that should be 100k miles

[AustinK425]

Dude I'm down to kick it hah Get to meet the infamous 5toes in person! Yeah that loose gunk thing is supposed to run down into the pan and muck up the fluid again, then youre supposed to flush it again in 15k supposedly. Dunno about that 15k thing but good place to start.

Fucking Christ now there's the E34 'bcuz 24v' kid vs. the Travel camper Derp showdown.

If you want to auto-x that car just shut up and do it. Anyone who talks about how much they want to do an autoX/track day is the person who never will.

If you're hell bent on spending money on your car for things like coilovers and shit then just start replacing wear parts first. Chances are by the time you're done with that stuff you'll have identically made yourself a nice car and will have realized that you don't want or need that other shit.

Lastly, if you're not going to listen to all the reasonable advice you've been given, just shut up, fuck your car up and post pics of what you come up with. Stop telling us what you think you're going to do and just do something.

I wont flush the tranny, I hear that loosens up the gunk and is bad for it.

I might just drain it and replace filter and refill with the good stuff

Im positive I said to change it a few times. I dont do a full flush with a really dirty trans because it can bring up too much dirt to suspend. I bet with dexron 6 this is even worse.

either change it a few times, and then do a full passive flush

or change it a few times and call it good.

If it is so dirty that it is messed up changing 1/3 the fluid in a filter change is just a first step. You should notice slight improvement.

do it 2 more times.

If the zf trans doesnt have a drain plug, you shoul get one of those cheap rred vacuum pumps and put the black tube intoo the red tube annd syphon a couple quarts out through the tranny dipstick.

do it once ( 1/3 clean 2/3 dirty) twice ( 1/3 clean taken from 2/3 dirty system apx half clean) three times ( 1/3 clean in 1/2 clean system apx 2/3 clean)

2/3 to 75% clean is now clean enough.

1/3 clean on a filthy system is not clean enough, its just step one.

what they call a filter in this type of transmission is just a grate that is stopping larger metal flakes from going back up after they come down.

Its cool to get rid of all the sludge on the pan and the filter at the same time, dont get me wrong. However, imo this grating never wears out and if you emptied out enough sludge and put enough new fluid it, it would be clean as new.
2 car generations ahead they stopped using these types of filters and just put in a reusable grate.

ooooooooooo thats what its good for the slip from a stop. or slip from 2nd to 3rd.

cant diagnose from a distance though I think its worth it.

[5Toes]

Ill try it.

Mine slips when cold a bit, but doesnt slam into shifts, and doesnt slip coming from a stop.
