Thread: Automatic Fluid Lost

Probably O.K.
Happened to me as well,realised I was losing drive,pulled over quickly,had a look and saw the floorpan covered in oil.
Had pipe fixed,fluid replaced,and as good as gold.

My understanding is that it all happens so quickly when the pipe blows that drive is lost so rapidly that nothing much suffers,(as long as you don`t rev the s....t out of the motor and check quick smart)
More likely to suffer damage from a slow leak and low gearbox oil level over an extended period than a sudden dump.

Trev.

I also have had this happen TWICE
First as with you the flex line blew off at the radiator end on the way to Cobar towing our van.The fix was simple just replaced the pipe and used worm drive clamps to secure,two each end. Refill and all go .
The next time it was a different story going from Moree to Inverell also towing the van wam! no trans but the oil trail under the girl was further back on the engine in fact on top of the trans. Tow in etc etc and it turned out that the inlet pipe on top of the trans had worked its self loose and dumped her again.No tread damage to the fitting did it up again with much difficulty and a couple of bent spanners and some bark off the nuckles,filled her up and away again.
But i must say she is still the best thing i have ever bought.

As an Auto builder, I would only be more concerned about "why" these events happened, as in what caused the hoses to break/undo.

Have you had work done at servicing, eg; radiators repaired etc? In haste and heat, a lot of spanner work can be only half done, and not "nipped" up. Over-thightening can lead to similar type problems, and not just with pipe work.

And as I understand it, the ZF doesn't liked to be reved when not moving, this can burn the friction plates in the clutch. And interestingly, I dont think too many cars do tell you if theres something wrong with your trans, (??) unless you have pressure gauging set up like we do in R&D.

Anyway, something like this could be disasterous if your towing out in the never never,,,

This is fairly common with D2 autos and I believe it's the fittings that are not the best. Other causes have also been bad batches of the rubber hose.

It happens coz the build quality is CRAP......like lots of the rest of the car, dont get me wrong I love mine to bits, but it does not digress from the fact it could be built better!!!.

My pipe failed in trafiic, revved it to go, and didly squat!, looked underneath and a nice coating of auto fluid all under the wheel arch and engine bay. DOH!!...

There is ONE good thing that comes from this, and that is the gearbox pump boots ALL the oil out rather well, so when you come to refill you get 95% of a fluid change done as opposed to just draining the sump on a normal service.

I took a few piccys, and did a little write up on my site. I changed both pipes as a precaution, and if I still have the car, I will do both again around 5 years down the line.
