Hold Light: Code 62

Post by **Ian** » Mon Sep 17, 2007 7:54 pm

Member Brian is stuck in Germany. Hold light flashing, gearbox defaulting to safe mode. Local diagnostic check indicates Code 62, "Over-running clutch solenoid". Is this expensive? And what does it mean exactly?

I had this but I didn't pay to get it changed.

It caused the car to revert to "get you home mode" after 20 min of driving and took ages to reset.

To cure it I had the solonid pack replaced may have just needed the 1 doing but the people changed them all.

Best to call on the expertise of an auto gearbox specialist

Is there any follow-up information on Code 62 or what happened on the original post?

I can't risk going any great distance any longer in case I lose top gear and the 'Hold' flashing at me (code 62). Could anyone point out where this particular solenoid is so that I can monitor it for malfunction or bad connection?

I'm very reluctant to give it to a specialist knowing that it will probably cost several hundred quid - could mean the impending end of the Bongo days!

I would order an exploded view of the gearbox but I've forgotten where I got one before - was it a N.Z. pay per page site?

isn't this a bit of an over reaction. Surely if Ian hadn't heard of this it's not a common problem. Maybe AA or RAC membership would give you peace of mind?

Stringman - not really an over-reaction - I think it's also happened to several members of the forum as well. It has happened to me about 6 times over the past year and I've had to drive home carefully for anything up to 50 miles.

Other members have overcome the problem temporarily by switching off and letting it cool down but it takes an age. Breakdown cover isn't much use as it's not really 'broken down'.

I use the Bongo as a second vehicle workhorse but I would occasionally like to overnight in it - if you drive 40-50 miles and the 'hold' light flashes and top gear is lost, what can you do other than, wait a bit, turn round and go home? I know it'll just happen again. Leave it overnight and it might not happen again for a month, or - just an hour later!

Doug - fully appreciate your concern. The only (cold) consolation I can offer is that our last car, a Spacewagon, cost nearly £8k and yet within a year its ECU went and it cost us £600 for a new one. I hated that but had to accept it had happened and move on. It never gave us any other trouble. All cars 'suck' sometimes - when they go wrong a modern car can sting your wallet. The real issue is knowing whether - having spent the dosh - the problem will be fixed. On that score, you'd think an auto-box specialist would be better to deal with than your everyday garage in that they will either be able to say what the problem is and give an estimate of cost to fix it, or they will be obliged to say "don't know this autobox so can't advise". Replacing the solenoid pack (if that's what it turns out to be) doesn't sound like more than a few hundred £ at worst and then you should have a good Bongo again. Without that it's either unsellable or a bargain for the person who then takes it to the specialist.

Don't know if the above helps but...

Good luck either way

The solenoid is on the valve block in the autobox sump Doug BUT......and it's a long shot.........remove/refit all the electrical connector plugs going down to the 'box and do the same with the multiplug which is also in the coolant sender circuit - it's the wires from the coolant sensor on the right side of the engine, under the driver's seat. It could be as simple as a dry/poor connection giving the autobox control unit a spurious signal.

The autobox/torque convertor lockup function (which you're calling top gear) is controlled by coolant temperature - it disables the "lockup" until the 'box oil is up to operating temperature.

I found this by a bit of chance and lateral thinking on Bumbly1's bongo when he had a HOLD light flashing.

Good luck........

I was wonderng about connections too Dandy but didn't feel confident enough to get his hopes up. Gotta be worth a try though before looking at more expensive options

In reply to Dandywarhol, if the solenoid is where you say it is (tagged BM13 on the rear end of the sump on the driver side) it is inside the sump and probably not repairable/replaceable without major headaches - probably a transmission specialist job.

As far as the coolant sensor goes, it has always been consistent from cold and the gears go into "top" after the first mile or so with the temp indicator at the same position.

I've applied WD40 to all the connectors and tried to plug/unplug to clean the contacts but I'm now defeated by the cold weather - any more will have to wait until the next time it happens.

Would appreciate any other thoughts or information on the subject.

This isn't the temp gauge sender doug - it's part no. 18 - 840C with 2 wires attached.

It's the sensor for both the torque convertor lockup (top gear) and the glowplug timer.

The solenoid in the gearbox sump would mean taking down the valve block I think - unless you've been in there before it would be worth letting a specialist to do it.

I'd still checkout the sensor wiring for continuity and the sensor values - they should be 2.3 - 2.6 ohms @20 degC and0.29 - 0.34 ohms @80 degC.
The sensor connects to the ECU terminal 2A

I have just posted a thread on here for the same problem Doug...sorry to hear you havent sussed out the 62 code out either....

After reading through your thread, Im going to get the other half to have a look on Friday....and clean up any connectors that he can get to without taking it to bits, as we are not mechanically minded....

I surpose the big question is????..........
Has anyone had this solonoid problem sorted at a garage and if so how much is it gonna cost me?

Doug · Post by **Doug** » Thu Jan 31, 2008 11:40 am

Many thanks for the replies - I'll do a few more checks as Dandywarhol suggests when the weather improves and wait and see what happens. The problem doesn't arise quite so often as I tend not to use the Bongo for anything other than short trips nowadays because I can't rely on it because of that very problem.

In reply to Bongo-Bubble, I read on a previous thread that someone had the solenoid pack (6) replaced for somewhere in the region of £400 - I would have thought it would be a good bit more than that in my area, hence my reason for putting up with it for so long.
