Water in my transmission

[JackCollo]

Hi guys
I've unfortunately been the victim of water attacking my transmission. I've got a 2000 GUII AUTO ZD30 and I rang a transmission shop and got quoted $4000 for a complete rebuild including fitment.

Can anybody give me any advice for the roller coaster that this is.
I am truely gutted about this happening
Have drained the water out of the trans and it's sitting on the street

Ouch , checked to see if you can get a second hand box .

Yep, what he said....... quite a few being parted out, and I hate to say it but the best places to look are on the many many patrol facebook pages

[JackCollo]

Yeah I've had a few friends who were unfortunate enough to get dicked over from the second hand box as well.

Not sure if I'd rather get one rebuilt or have a gamble with a second hand box

[GQtdauto]

Do you know where the water came from Jack , was it from the radiator or did you have some submarine action .

[JackCollo]

It is the radiator I know that much for sure.

[GQtdauto]

That's it , I'm putting in a dedicated cooler for mine .

[JackCollo]

Yeah what's annoying is they already have one so just get someone to block of the entry into the radiator and redirect it to the seperate oil cooler

[GQtdauto]

Mines a GQ , so only have the radiator but the tran oil coolers are cheap as chips , going to fit a temp gauge as well so I better get on with it .
My radiator is only a couple of years old .

[JackCollo]

Yeah not a bad idea

have you tried wholesale automatics ???

[JackCollo]

Are they any good?

[threedogs]

They sell toughened up Autos for all applications
LS1 conversions etc, wouldnt hurt to tell them
what your after They will have one in stock maybe
on a change over basis Im not sure.

I had no drama dealing with them getting parts sent from them in Melb to Syd.

You will probably be looking around the 4g fitted anywhere you go :(

[JackCollo]

Yeah unfortunately it's a price I'm gonna have to pay but I really don't wanna cheap out and have a second hand trans come back and bite me in the ass

[JackCollo]

Will more water cause more damage because it was properly full of water not just a little bit.

Note that it has all been drained out

[GQtdauto]

Think you would have to completely disassemble box and clean all components but did you drive it how far etc may come into it , if answer is no you may save it by removing and thoroughly cleaning but not an expert.

[NissanGQ4.2]

Did you have any symptoms of the box failing before finding the water?

[JackCollo]

No I drove it into my driveway and flushed the radiator out. Bled the system of air bubbles and then when I went to reverse out of the driveway it wasn't staying in gear and wouldn't drive forwards or backwards

Then pulled the tranny dipstick to see a beige coloured liquid that isn't tranny fluid and after that I dropped what ever the fuck it was out of the box so now it's sitting with nothing in it

[JackCollo]

I was told that maybe I could try to flush the crap out with atf. And see if it will still drive and if it doesn't just to leave it be.
Any thoughts

[garett]

yes sometimes it works again by flushing it with atf. its worth a try but i wouldn't take it far from civilisation for a while. sometimes there fine but sometimes it just works for a little while if it works at all.
done it with a couple falcon 4 speeds 50 50 if it works

[JackCollo]

about to upload a photo of what drained of the trans and you can all tell me how fucked i am

I'm going to try and flush out the water tonight with new tranny fluid and trans flush.
Then fill up again and cross my fingers

I drowned a MB Gaelenaden wagen over the roof many years ago. The auto filled with water as did the rest of the vehicle. i managed to winch it out of the hole using a warn low mount and after a lot of effort, drove it home. I took it down to a local automatic specialist and had them do exactly as you are suggesting. The auto trans fluid was the colour of pink ice cream. The auto had just started to slip at this stage.
Anyway, after a $400 bill from memory, the new fluid went in and no difference. the water reacted with the organic friction linings and it was a total rebuild - took it to MB and they refused to rebuild - only factory new. I went to an aftermarket reputable automatic reconditioner and it was never the same - vacuum advance on the auto just would not work, all new 'everything' - cost close to 10K. Lesson for me apart from being a dick and not testing the depth of the water crossing, was to not try and reco a transmission. I am sure many 'brown dog' transmissions have been overhauled with success, however i wonder about the finesse of the finished product. Mine was never the same and a disappointment, so I guess, just be aware you might be heading down a path or disappointment. The insurance wrote the vehicle off, which turned out to be a godsend as the dealers were out to extract every cent from a service - like driving down the road and throwing 'hundreds out the window'. So happy I bought the patrol after that.

I have some good news. I filled the car up with trans fluid and liqumoly auto trans flush. And I was shifting through the gears and it jumped into gear in reverse and drive and I got a bit excited and gave it a bit of throttle and it drove forward. After filling it up I drove it around the block a few times and it didn't slip once just a bit rough but slowly getting better.

Will drain the fluid and flush from it in the morning.

[JackCollo]

Just a quick update. Had the transmission professionally flushed this morning and topped up with fresh fluid and drove like a dream.
Just like it did before.
Won't do anything to hard just yet and will nurse it back to its routine of trailer towing in due time.

Thanks everyone for your help
