VS AUTO problem> oils goes black after oild changes.it wont engage in mornings start
my auto in the vs from cold start doesnt engage till after a minute or so of idling .other than that it works perfectly
. the only problem i have is because it doesnt engage at cold start the tranny oil goes black. so i have to keep constantly changing the oils and the filter on a monthly basis please help needed to fix this
VR Buicks > You ;)
That sounds terrible, what are the error codes indicating?
ummmm that does not seem to good
might be needing to get a rebulid done on transmission
sounds like it could be blocked somewhere and just cooking it if its goin black that quick

Not dissin' your abilities as a home mechanic in any way here, but do you completely flush your trans and radiator trans cooler tank with your service?
Just that even if you change the filter and fluid, dirty, burnt old fluid will still be in the trans and cooler tank, which u need to flush out before your service is completed, otherwise it will just dilute the new fresh fluid, turning it a dark murky red, or brown-ish tan colour, depending on condition, instead staying a nice clear-ish red.
But If you have been flushing properly, then it's either time for a trans rebuild, or just replace it with a reco'd unit.
In any case, 'black' auto fluid is definitely a sign your trans internals could be in dire critical condition.
EDIT: Do you know the history of the trans? If it has been used a lot to tow caravans, car trailers and the like?
These auto's really don't like this kind of heavy towing work, and will overheat and burn the fluid very quickly, if not kept cool with a separate trans cooler.

the auto had probllems when towing one day it went into limp mode and eventually could only take off in 3rd gear and 4th so the 1st and second went
so wehn i got home i had to fix the 2solanoids which selects the gears that fixed it self up so all gears work but at initial start in the mornings when the car hasnt been driven for a while i.e a few hrs the car wont engage any gears till car pumps oil through i am guessing i did all the oils changes right and it stays a red color for a short time coz the morning starts as this only happened after that faithfull day and i had to drive it like 30kms home after wards like thtwithout the trailer though

I don't know a real lot about these later model transmissions, but it's sounding like the clutch bands inside have basically been chewed away to the point they are barely working.
It could be that it's the material from these disintegrating that's turning the oil black, this could also be clogging up a lot of finer parts of the valve body, making it difficult for the fluid to flow through the areas it's supposed to, and why it seems so hard to get it moving when it's cold.
Best advice I think would be to visit a few transmission specialists, tell them the symptoms, and get some quotes.

i seem to think its like a pumping of oil around the tranny that is causing it to go black
did the problem start after a fluid change? if so..
did you use the correct fluid?
Gotta use Dexron 111 trans fluid.
yes used the right oil etc it just doesnt pump the oil around on cold start to get the gears to engage and shift for about 30secs then once it engages it all works fine even with the dark oil in it. if i can fix the cold start bit everythign will work i think
The problem with your transmission is that the 3-4 friction clucth are burnt, so even how many times you change the oil it will turn black, this happen when you drive the car in limp mode for that long even not towing. and also overheat the tranny oil will make the piston seal became hard, and it cannot built oil pressure thats why it wont engage in the morning or when its cold, when it warm enough this seal became smooth or expand again and back to proper sealing again.
i hav also changed 3solenoids in the tranny not sure which ones they were but i hav another old tranny tht was working from it i got the parts
so where is the part or do u hav a diagram or any idea of some part of a manual i could find for it so i can change that part as i am fairly handly with cars etc any information would be \great help

You would basically need a full transmission rebuild kit, it's not a small job, best left to professionals really.

Real cars are steel cars.
Check the flow through the cooler, especially if fitting a reco trans, as they have a habit of becoming partly blocked causing the trans to overheat.
With the line out of the cooler disconnected you should have a good steady flow of oil. A workshop manual shoud give you the flow rate.

i had the same problem with it not engauging at cold start, wait a min or 2 then away she went, i found that the filter had fallen out of the valve body resulting in the fluid not been able to pump and it was just sucking air, trans fluild expands with heat so after a min or 2 at cold start the fluid was able to then do its job, drop the pan and make sure the filter has not fallen out, good luck

and while you have the dirty filter out, cut it open and check for metal filings etc.

Filter falls out when filter seal goes hard. Some people replace the filter without replacing the seal.
The seal is the only thing that holds in the filter.

I have a similar problem, i have 1st and 2nd, but when it goes to 3rd, nothing, may as well be neutral, do u think this could be solanoids?
