I dont want to cause an alarm,
but i'd drain the fluid immediately and put Honda WP-1 in there.
How many quarts does the tranny hold. If more than 3 quarts then 8 ounces mixed in isn't really a big deal as far as possible solvent damage however if the tranny had alot of build up,and the mmo cleans it up it all goes into the fluid. If there isn't a filter then it may be wise to flush the tranny and put clean fluid in it.
If the unit has significant deposits the mmo may loosen something and cause a serious problem.
And flushing all the fluid if its never been done before could open a whole new world of hurt.
Transmissions are kinda mystical. I've seen trucks that never got the fluid changed and 300000kms later someone decides to do a flush then suddenly the tranny fails. And then there's some that fail even when maintained properly.
I've got a friend who is a tranny expert. This guy is something else.
Anyways he said to me that if the tranny fluid hasn't been changed by 100000kms he said dont change it,at least not all at once. No more than 25% of total fluid capacity tops,then drive 1000kms and do it again. Repeat until the fluid in the tranny looks new again and not burnt or darkened.
He says most of the trannies he rebuilds are from people doing a full flush,usually from a shop selling the flush special type deal on high mile transmissions that have never seen a fluid replacement.
The new fluid loosens up layers of varnish that plug up those small valve bodies or whatever and cause damage.
He says on trannies that have been properly maintained this is a non issue because the insides won't have any deposits that can potentially cause problems but neglected ones need to be done with fluid swaps and only a few litres at a time,so that the deposits are cleaned slowly and the fluid can dissolve them rendering them harmless. I'm sure it was never more than 25% of the total fluid capacity be removed and replaced at one time,then ample miles,then repeat.
This method never introduces too much new fluid that could potentially try to attack deposits.
He has a great rep and I respect his opinion.q It also makes sense. Especially if there isn't a filter. Even if there is a filter who says a chunk doesn't come loose in the middle of the system somewhere plugging something and it never eats to the filter.
Now if your tranny has been properly maintained with prior fluid drains then I doubt the mmo will cause any harm because there will be very limited deposits to begin with right,but if its a neglected unit then slow and steady with fluid transfers and forget the flush type products.
I've used many solvent type flushes before and even used kerosene,diesel and acetone(not at the same time) in various engines.
I was never really concerned because nothing I had was vvt or mds equipped,which means the oil passages aren't pinholes and en if something did come loose it would dissolve fairly fast because of volume and pressure. An automatic transmission has thousands of tiny fluid passages and if flow is impeded somewhere in that system you could lose gears.
I gotta ask. Was there some kind of problem you were trying to address with the mmo or.............
