Bongo Fury

Hi all my 96 bongo has just started to perform strangely regards the auto box if I am driving say at 50- 60mph and the box is in over drive if i start to accelerate operating the pedal very gently the engine seems to over rev up to approx 4000 rpm as if on a manual car when the clutch was slipping then it will start to grab on to 4th gear it never done this before I went on a 300 mile round trip yesterday the fluid was changed approx 2000 miles ago and is at the correct level.
Has anyone else had a similar problem and if so what was the cure.
Cheers all.

If I was you, I would get it checked out by an auto box specialist asap - If it goes totally it will cost you alot.
£1,700 approx for a reconditioned box and labour

No one any info then thanks to those who took the time to read it any way.

DONT LIKE THE THOUGHTS OF HAVING A £1,700 REPAIR BILL

You're a bit impatient bongopatrol........

Firstly - it doesn't have an overdrive - it's a torque convertor lockup and it sounds to me that it's faulty or the sensor which activates it is.

Does the "HOLD" light flash????

Hi dandywarhol sorry if you think I am a little impatient the problem is I am very concerned as i am heading away for a week next weekend and feel it best to get it sorted before I go.

The hold light is not flashing .

When driving the lockup does operate then when I go to accelerate it just over revs (ie like clutch slip) until eventually it kicks down to what I would say be 3rd gear then goes back into 4th then re engages the lockup.


Where is the sensor you refer to? so I can check connections etc.

Sorry BP I don't know about the lockup operation, I just know there's a temperature sensor in the same circuit as the glowplug relay which locks out the lockup until the coolant temperature gets to a predetermined level.
There's also a fact sheet on the gearbox and it's sensors in the member's area

I'm a bit confused about your expressiopn 'overdrive'

The gearbox should be normally be operated without prssing the hold function.

If you drive without the hold function it will automatically use the highest gear it is comfortable with.....you'll do about 65 - 70mph at about 2500 revs. put your foot down slowly and the van will go faster and the revs will increase.

If you put your foot down hard the gearbox will go down a gear to give you more revs for overtaking etc.

If you press the hold botton the engine will change down to the next lower gear and stay there until the hold botton is disengaged (press it again).

If you are driving in 'D' with the hold light on this means that you are driving in third gear and to drive at 55 - 70mph you are going to have to rev like hell.

Hope this has helped. If you'd like to discuss it over the phone please pm me and I'll give you my number.

good luck

Hi guys thanks for the replies it turns out that the 4th gear clutches are worn and looking like its going to be expensive to fix .

Well everyone got my auto box back from Dunnings auto transmissions yesterday and I refitted it last night all is very well and my bongo is driving better than ever so I'm over the moon apart from my bank balance is a lot worse off but you know us and our Bongo's we just love them.

Great news Bongopatrol

If you take a sharp left out of your drive (or a sharp right) and follow the signs, you'll arrive at SUMMER.
