Rob sunk his in water for 5 MINUTES. Klye's was swimming for 30 minutes and the OP sank his in water for 6 or 7 HOURS! He got it deep enough to get the tcm wet so he got it deep enough for water ingress into the transmission
Just to make things a little clearer, here's my situation:
I was in the water just long enough to jump out the window, pull the strap off the hood, hook it up to the rear, and get the guy behind me to yank me out. The water never even equalized in the cabin, but it did cover the TCM and the amp. The speakers started making all kinds of bad noises until I unplugged it. And I unplugged the TCM.
I cleaned the TCM and it was fine.
I've been through deep water many times. The problem appears to only happen if you stop moving.
Here is what the fluid looked like after the transmission failed. This is a few 1000 km after it had been flushed thoroughly (5 gallon pale of ATF). That's clutch material clouding it, not water. I had just started to think it was going to be ok, when I was left stranded.
Inside the filter.
I hoped the trans losing drive was due to a clogged filter. So I changed the filter and ran another 20L through it. No dice. The trans worked, but it didn't feel good and I knew it was just a matter of time. Not wanting to be left stranded again, I solved the problem once and for all.
manufactures have tested their stuff under their own controlled environment and then printed the findings or told us techs what they have, but 10yrs down the road or 10's of 1,000's of miles later only the user knows the results.
Yes. I was an OEM engineer, we used to say "9 women can't make a baby in 1 month". You can only accelerate testing so much. There is no way to really test a system with 10-20 years of use within a 4 year product development cycle.
That being said, the factory only tests to 24" of water anyway.
How/why does Crystal think the MAF was bad? Never heard of a MAF causing limp mode. You can (and I have) driven with the MAF completely unplugged. You almost wouldn't know it.
I would expect, if no water got in the trans,and you replace the TCM, everything else will be fine. The trans connector is a really good design. But check it. Mine was factory-clean inside after all it had been through.
even with a tea spoon of water in it as that trans would go bad just idling.
Not true. I drove all the way home before I could flush it. Ran fine. Didn't even know anything was wrong. After flushing, it still went 1000's of miles before failing.
Like i said wd40 saved some of my ecm.s.
Maybe there was a better alternative but at the time it is want i had.
I now carry the electrical contact cleaner full-time. It's way better. Brake cleaner works too. That's what I used on the amp. Amp still works to this day.
Since when does disconnecting a battery reset any of the computers on a D2?
Sure doesn't! I left my battery disconnected for a month, and when I plugged it back in, my 4 Amigos were still partying!
so "you will be surprised how resilient they can be"
It's all in the timing. Power must be removed from the device IMMEDIATELY. Then, it must be cleaned ASAP. Fresh water can work in a pinch, but it MUST be blown out thoroughly with compressed air before you hook it up again.
I actually left mine sit on my black hood in the sun for an hour to dry out before I got back to camp. Maybe that helped.
