Gearbox Problems

[3ddesign]

I've fitted a new engine to my GV, now it won't change out of first gear, code says  could be bad ground. No power getting to the gearbox.

Does anyone have a schematic of the multi pin socket so we know which wire provides power ?

Thanks,

Full workshop manuals list here, the elusive copy of the RG diesel is here.

Thanks for the manuals, would be lost without them.

Now we seem to have a bad earth from the left most relay on the front chassis crossbeam. If we run a wire from it to the battery negative we extinguish the engine lift on the instrument panel, but the relay clicks rapidly.

Have we missed something ? Is this the relay for the transmission ? The wires on this relay do seem lighter than the others which makes us wonder. Also the PCM relay in the fuse box doesn't seem to be connected to this relay ?

Any help appreciated,

 

Thanks

Could you provide the Fault codes currently present on your dash?

 

I've attached an image - On the left is the relay I assume you're referring to ( "front chassis crossbeam") 

                                     - Then on the right is the location for the transmission control relays position ( which i presume you're possibly referring to as the "PCM relay" ?)

I think we're getting close. The relays on the front crossbeam threw us because they seemed to connect to the relay in the fuse box.

 

for some reason in my car the relay #1 is labelled fuel lift pump, but we'll assume it's wrong for the time being.

 

Will post later if we get sorted, thanks

[3ddesign]

Finally sorted.

 

Was the fuse wire from the battery to the transmission relay.

 

Thanks for your help in getting me the manuals etc, much appreciated, Mark.

turns out the new engine blew the head gasket after a dozen miles !

 

Being replaced by the breaker but still have to fit it all over again.

 

One question,

 

Are the injectors on the 2.8 CRD tied to the ECU of the car ? Or will the ones on the new engine work ok ?

 

Thanks

[ryden]

The injectors aren't bespoke/programmed to each cars ecu, if that's what you're implying? 

[mikebh8]

If the engine is "identical" with the one on the car, it should work with no extra work.

[3ddesign]

Yeah that is what I meant, should ok, engine exact same only this one has AC compressor ( which someone welded solid on my own engine ) fitting new timing belt water pump etc since we're going to all this bother.

 

I really would like to think we'll be ok after this.

 

On that note , where do I fill the AC from ? I'm sure I saw two locations that look like fill valves ?

[mikebh8]

At this stage is not enough just to fill the system, it needs vacuumed and then refilled.

You want to do it yourself? Here is what you need:

While there, I'll check the oil in the compressor, if it was removed and place upsidedown, more likely came out, plus a replacement doesn't do any harm.

 

A vacuum pump which vacuums to a minimum of 29.9 minHg, I made one from a fridge compressor.

 

A precise kitchen scale.

 

And obviously the gas according to your car, most likely is r134a( find out how much).

If there are no leaks and the vacuum stays constant for at least half an hour, you can charge the system. According to compressor's specs, you will have to keep the bottle upright or upsidedown.

 

Complete how to videos on YouTube.

 

If is one car only you whish to do, you're better off taking it to a shop where sometimes the leak check is free.

However, answering your question, when you buy the refilling gauge and gas, it will only fit one side.

 

Hope it helps.

Thanks,

 

I'm hoping my luck is changing on this saga !

 

Seems the engine the breaker replaced with has had a timing belt water pump etc changed very recently. Still has the markings Goodyear 46510639F on it and virtually no wear on it or the pulleys. Is this a good quality belt ?

 

My background would be hydraulics so well used to seeing gates but not goodyear.

 

Thanks

[mikebh8]

I don't remember the brand that I used, however when my engine failed, after only few miles with the new cam belt, I kept it and used it on the "new" engine, it still works. Also, Goodyear is meant to be a good rubber brand.
