MK3 AUTO GEAR BOXES????

**Golf Loon** · 03-04-2006, 08:04 AM

Right, under the scuttle panel the gearbox loom and ecu joins the car loom with a 4? pin connector or thereabouts. If you unplug that and plug my loom, ecu and gearbox in. That should be that.

Does that sound like what you have?

Hi Golf Loon...

Will be checking that out shortly.

Whats the latest on the 'rogue' box?

Get back to U.

Hi again Golf Loon.....just another question came to mind..............

your box, loom and ECU is of a 1.8lt car.....and although the gearbox & ECU should be 'stand a lone'.....it is still connected/pluged into the engine loom and accordingly the 1.8lt and 2lt engines would have differing rev rates for the gear changes..............so would not the 1.8lt ECU be tuned to the 1.8lt engine and if one hooked it to the 2ltr engine it would be out of sync...............and maybe thats why our box has 2 additional sensors?

Kindly run that by your mate.

Hi Golf Loon..................another point that has come to light with this can of worms.............are the gear ratios in the 1.8lt box the same as in the 2lt box???

Hi Golf Loon................here is my latest up date on this can of worms after making numerous phone calls to the 'experts'...

1. Golfs have a sticker in the boot on the body panel infront of the spare wheel (inside directly behind and below the number plate) and on that sticker amongst other things it has the CODES for the type of engine and transmissions fitted to the vehicle.

2. On my daughters Golf the Engine code is: ADY and the transmission code is: CLK. I have been told that transmissions with different codes are not compatible.

3. The transmission code stamped into the top of the bell housing of your gearbox is: CFK which they tell me is not compatible with my daughters vehicle.

4. I have also been told that the gearing in a 1.8lt auto gearbox would be different to a 2 ltr auto gearbox.... all to do with engine revs and change down/up sequences.......maybe thats why the additional sensors on our box?

5. To test the transmission CODE theory I rung up a large VW wrecker in Melbourne and said I was looking for a Golf 95 model auto gearbox and the first thing they asked was ....'What transmission CODE?' and then they informed me that all auto gearboxes are not compatible.

So sadly Golf Loon looks like I will be shipping the gearbox back to U....and my daughter will be spitting chips big time as she will be up for considerable more expense.

Will send U U2U with bank details for refund.

Regards...............Doublecab.

Looks like a fait accompli. Pardon my French, but I've been watching this thread with great interest but I haven't interfered because there's been a lot for all of us to learn from the exchanges. Knowledge of this type will always be available to all (including visitors) when they do a search of this site. A pity the outcome wasn't a happy ending, but full marks to all concerned for your persistence, polite correspondence and vigourous research. It's all part of being an enthusiast and you're a credit to the forum

Well said Brackie.

Send it back to me Doublecab and I`ll gladly return monies to you.
Serves to remind me why I hate autos. Should have slung this one in the river.

I was told that they were all interchangeable by well known expert!
However, I did not know your car was a 2L when it was sent, somehow that question never came up!

CLK and CFK that is the number we needed, not the one you printed before.

A smaller capacity gearbox works well with manuals, making em rev quicker. In theory, the same is true of an auto, but in practice, who knows. Especially complicated electronic ones like this.

Sorry for the inconvenience you and your daughter have been through.

However, as Bracki says it will help people in the future attempting this sort of job.

Well said Brackie....and as I said previously ....no malice EVER intended...we all learned something about auto boxes....was hoping to the end, that there was a simple solution that would save my daughter bucks and enable a simple straight forward fitting of Golf Loons gearbox.

Sadly twas not to be............and Golf Loon is/has been up front all the way along the line, which to me means I will have no problem having any future dealings with him as I am sure there will be.....having a garage full of VW's and two daughters with VW's.

Just got a thought....maybe we should have a 'technical archive' on this site were all know VW data is cataloged and stored.........just a thought.

Hi Golf Loon.............looks like U were writing the same time I was writing but U got your post up before mine.

And yes we all learnt something......and one of them was that VW's and German engineering is like the weather..........a **** load of variations....a bit like Victorian weather.............3 seasons in one day.

As I said previously.....will have no probs conducting business/or recomending U in the future.
