Has anyone ever seen this before

Howdy all,

I bought a 2002 VX Aclaim this week it was a repairable write off that had flood damage.
A second hand engine and gearbox was put in the car as the previous one was stuffed from the water damage.
The replacement motor had done 150k and seemed to be running perfectly and it drove that way to, So I finalised
the sale and went through all the hoops to get it re registered.
I was on my way to my regular mechanic thinking everything was fine but wanting a further check done from someone that I know
for piece of mind and a few minor things not working correctly.
The few minor things sorted and my mechanic went to check the tranny fluid when just as he touched it it exploded with hot fluid
spraying all over the place and smoke everywhere due to the extractors being hot from running.

We are both not sure what the hell happened as my mechanic said he has never in his 20+years seen this happen before and me well I am
not really that mechanically minded so it blew me away completely.
Has anyone seen this before and any ideas as to what the problem could be?

He has checked for codes etc and nothing is coming up just 0012 everything ok

looking forward to reading your thoughts

John

any thoughts guys ?

what exploded? around the dipstick or the pan
if as he undid the lock on the dipstick the oil blew out the tube i would think trans is being pressurized from water turning to steam inside pan

Sounds like your breather hose is block

The Dip stick exploded it just shot straight out and launched into the air with the fluid going everywhere.

Holden had a problem with the early 4L60E's in the VR I think it was.When the transmissions were worked hard and got hot, like when towing a heavy caravan or whatever uphill, the dipstick would blow out of the tube and trans fluid would spray out of it everywhere all over the engine which was a bad fire risk, so they recalled them and fitted the locking type dipstick, which has been fitted to the 4L60E's ever since. Maybe its overheating somehow.

Are the transmission lines run through the radiator properly? No blockages? Hard to say what's caused this.

+1 sounds like your lines are blocked somewhere / I've also heard your radiator cores can crack internally and can leak coolant into the trans lines

 

[capitalgainz]

blocked breather is your issue

+1 for blocked breather.

Had the exact same thing happen the first time a mate and I tried to check his trans fluid / do a trans service.

Scared the farken **** outta both of us
