Water In Bfii Zf Automatic Transmission

[walkerstreet]

Hi everyone,

My BFII XR6 Turbo's been at the dealer for over a week and a half now. They're waiting on a new automatic transmission to come from interstate.

It had started to shudder and creak, rocking the whole cabin, at ordinary speeds (anywhere from 20km/hr up to highway speeds). If you changed gears, or accelerated, you'd feel the car rock through the leg that was planted on the throttle. Sometimes there was a crunching sound.

I'm not mechanically minded, but is this what they call "driveline shunt"?

The mechanics at Ford found water in the ZF 6 speed auto transmission, which had basically stuffed the internals of the transmission. It's been put down as a manufacturing fault (the car is just over a year old) and being fixed under warranty.

A friend of mine had the exact same diagnosis for his car (at the same dealer). He has a BF Fairmont Ghia with a ZF 6speed transmission.

I've heard of driveline shunt being a problem with BF's and the new FG. Is it the ZF that's at fault? Don't get me wrong, driving with the ZF is the best thing since sliced bread. But could there be a problem with a percentage of them?

Penny for your thoughts guys?

Thanks .....

Walker.

did they sat it came from the radiator, the water that is

That is not driveline shunt.

Without a doubt your problem has been caused by the trans cooler splitting allowing water into the trans oil.

The ol engine full of auto trans and a trans full of water trick ay..... Bugger....

Have they replaced your radiator for you also?

[our06t]

it was a problem with some of them having the trans cooler picking up water if the radiator gets a leak ,thought that would have been sorted by the bf2 though

I didn't think the trans cooler for the ZF was setup in the radiator like the 4 speed auto is. Could be wrong?

Correct ... the trans cooler isnt part of the radiator with the ZF box but instead it utilizes a small compact oil to water heat exchanger at the front of the box on the left hand side. If the heat exchanger core fails coolant simply enters the box ... so despite their small size and high efficency they have one big major disadvantage unfortunately

I should replace the heat exchange with an air to oil type on my BF F6 before this happens on mine as this problem has arisen a few times on the forum now and all within the warranty period luckily

Good point, I will be taking the same approach

I think process west was developing a trans cooler for the ZF box.

Pardon my ignorance, but do you mean a separate transmission cooler ?

Anybody know if this has happened to any Typhoons.Its a worry if it moded would FORD still replace it under warranty.
