D2 auto temp.

Now & again the auto box temp light comes on, mainly going up big long steep hills. It goes out after a little while on the flat. I had the fluid changed not long ago.

Any ideas?

Low fluid level, due to not being set correctly with engine running, maybe? If that is the case, sort it quick or you'll fry the clutches and need a full rebuild! Sounds like not enough oil in box, so what's there is working harder..... Maybe's they checked the level with the engine not running....... doh!

Procedure:- Level ground start engine and allow to idle undo filler/level blanking plug (front face of g/box sump pan) select all gears in turn with foot on brake back to "P" add oil through hole until it is up to the level of the hole (dripping) refit blank plug switch off.

DO NOT switch off with blank removed, or remove blank without engine running, you'll get oil everywhere!!! This is due to the fact that approx.

2.5ltrs will drain from torque convertor back to sump when stationary (ery - sp?). Correct oil is DexronII, or Dexron III, NOT ATF. Badger.

I'll check it out asap, cheers matey. If it's OK, any other likely causes?

ATF *is* generally Dexron...

Tim, Dexron is a type of ATF. ATF comes in various types, all of which are mixable in the same gearbox except Type D(II or III) which is Dexron. A ZF box will run fairly happily on anything up to type G, but only if it's assembled using that as a seal lubricant and filled with nothing else from day one. ZF recommend types DII and III, so that's what I recommend for them. I know from other's bitter experience that putting "normal" ATF in an auto that has Dexron in it can cause sudden clutch failure in the middle of a hillrally....... Badger.

It's always possible that the temp sensor has picked the same time as the oil change to go on strike.... very unlikely but not impossible. Also a very, very slim possibility that an exceedingly crap grade of oil has been used and it can't transfer heat at a sufficient rate, but that's a serious long-shot and extremely unlikely. My best guess is fluid level - less fluid = harder time for what's there = more heat. Badger.

On or around Mon, 18 Jun 2007 16:23:08 +0100, "Badger" enlightened us thusly:

stationary is standing still. The other kind is what Staples sell.

could also be if he's been off-roading the transmission oil-cooler is crudded up?

Hehe, I couldn't be arsed reaching for the dickshunery that's on a shelf 1 foot to my right....

Very strange it happened straight after an oil change though, that's what made me think maybe the level had been set incorrectly. Badger.

I remember it by - stationery is what is sold by a stationer.

Heh. Been there, done that. Offroading one day, pulling a caravan home the next, smell of frying clutch bands etc.

I aint got any to fill it up if it is low ffs! I must have chucked my pack. I'll take it to work, let it cool & do it at work tomorrow. Or, i might just go on my bike & f*ck it until i get home, sorry, you have to wait a bit longer....

I checked the cooler, thats the front smaller rad of the three rad looking devices, i presume?

Oil cooler, intercooler & rad?

Ya bugger! i just had to have a look. It is low, seems odd when you have the engine running above you & a plug out like that!

I'll get a couple of litres tomorrow.

Here's mud in yer eye Brian, ta matey.

This was on a Disco 1 where the trans oil cooler had been mounted below the radiator to allow for a JF intercooler above. On the D2 it's part of the radiator/intercooler assembly, so it's unlikely to be blocked unless you've been wading in mud up to the door handles.

Mind you, this is Nige we're talking about ...

Yep, every part of you says "I'm gonna get wet, here".

So come on then, how much did it take then? Badger.
