Anybody know anything about these gearboxes, particularly the problems
causing them to stay in 2nd and 3rd gear

Will too much oil in the box cause problems?

Any books or manuals on these gearboxes?

Cheers

Martin

What's an 'invecs 11' auto box?

It's an auto/semi-auto type of thing. Used in Mitsubishis IIRC. Move the
lever to one side and it's a semi-auto...like the ones BMW/Audi (?) use.
Brain's not working tonight :o)

Best of luck fixing the bugger...that's all I know about 'em.

Too much oil will cause overpressure problems and will blow out of the
dipstick pipe.
Also the N will flash.

Too little oil will cause overheating - flashing N and box locks into 3rd,
get you home mode.
The above will also happen if oil and filter are not changed as per service
routine.

You will have to give more details of any problems you have to be able to
give you a better answer.
It is a very complex box with alot of sensors etc.

Greatly appreciate your response

Now I have to clarify a few errors

The car is a 1993 Mitsubishi Spacewagon (about 50K miles), and the box
is an invecs however I'm not sure that it is an invecs II

I have actually been advised to get it checked by a professional (I've
been quoted 120 quid just to diagnose the problem) but before I do that
I would like to see what I can do.

I recently bought the car and found that it goes into 4th when very hot
after hill climbing.

The fluid level in the box was far too high so I drained some out, and
the car picks up better in 2nd but doesn't appear to use 1st or go into
4th. Actually I checked again this morning and the fluid level is still
high. I can't belive that this would still casue problems are these
boxes that sensitive to oil level?

You mentioned changing the oil filter, can you do that on these boxes I
didn't realise there was one.

In which case I'm better off changing the oil and filter before doing
anything else.

Thanks for your response

Martin

Don't suppose the handbook says what it's meant to do in 'winter' mode,
if it has one? Locking out gears is common in these. Might give a clue.

And the gaining in fluid-level: it hasn't got a transmission oil-
cooler built into the radiator, has it? Bad things happen when
coolant gets into the transmission-oil, or vice-versa.

1993 is InvecsII
Oil and filter change is due to start with, no matter what.
Oil must be Dexron III and use a genuine Mitsi Filter.
Bad news is the oil is about £8 a litre and you need approx 7 litres

I would take it to Ralliart, Dudley for a diagnostics check. If the oil
change doesn't help

Make sure that you only check the oil level when hot.

Sat right on top of the box.
One other thing you can try is an ECU reset. The InvecsII box learns your
driving style which means depending on how you drive it will decide when to
change gear ie. drive hard and it will change higher up the rev range.
sometimes they get confused.
Disconnect your battery for 30mins this will reset the ECU and can sometimes
improve gear changes.
I would take it to Ralliart, Dudley for a diagnostics check. If the oil
change/ecu reset doesn't help.

It's things like this that stop me buying an auto. They might be generally
reliable but when they *do* go wrong...SHEESH!

I wonder how much a new Mitsubishi auto box costs?

Well, a manual will usually have one or two clutches before an auto gives
trouble. And may have lost some or all of its synchromesh.

Like anything, it *should* be repairable. If tekkies with the skills can
be found.

Very true.
The Invecs box needs as much care if not more than the engine with regard to
oil changes.
As you happen to mention clutches, the InvecsII has seven clutches inside.

> > I wonder how much a new Mitsubishi auto box costs?

Well s/hand they are approx Ł1500 and anywhere between Ł500 & Ł1000 to fit.

Not really worth repairing the main box.
Sometimes some of the sensors get replaced but that normally is it.

Thanks to all you guys for the comments and advice

I'm going to change the oil and filter as Jester recommends.

You are quite right it is the first place to start

Nothing in the manual about winter driving but it does say that when there
are problems with the box it will 'fix' (read lock) in 2nd and 3rd

I don't think there is much wrong with it, but then I'm not too familiar
with auto boxes and one mechanic I spoke to recommended replacing it. At
over 800 quid for a beat up secondhand one, forget it!

I might get the ecu checked out because they are a common source of
problems.

Anyway, cheers for the responses

Martin
