US over to europan.
Hello
Its me about the transmission. Now i really confused. One tell me i just ave to change the C-solendion and one say TCU. And when i think i understand, Then its not work? Can i RELLY use this tranny or NOT? Can i JUST cange the C-soledion? Or must i Change the TCU?? Sorry but i relly need help to understand this. My car is allmost done now, i relly like to drive it again. But i dont understand a thing about this Tranny trouble. What must i doo and what can bee done?

Re: US over to europan.
You have two options.
1.Remove the US trans and install the proper VTD transmission. 2. Experiment and fit a new solenoid C inside the US trans. This is what you have been waiting for, I hope sooner than later someone can get it to you. IF not, I have a used VTD extension housing here, I could send one over if needed but I would rather not take it apart. Tom |

Re: US over to europan.
Ok. so that is my only option if this can possible work.
To change the tranny rigt now i cant afford. So then i just have to hope for the s-solenoid then? Quote:

Re: US over to europan.
Aside from the *random speculation* about whether changing the C solenoid can enable a Euro TCU can operate a US gearbox properly, there is another issue.
I'm not sure if anyone has mentioned this yet, but the Euro TCU will not work with the US Speed Sensor 2. So you will need to fit a euro type speed sensor to the US gearbox. That has been done before, there's a long thread about it somewhere.

Re: US over to europan.
The correct solenoid valve, matching the US transmission is already in place. The next step is lo fit a matching US TCU, and make whatever associated changes are required.

Have some one the part number on this?

The solenoid MUST match the transmission in use, NOT the TCU. The same increasing/decreasing pulse length signal, is applied by both TCU. The "phasing" is NOT reversed. This IS the very REASON for the different solenoids in respect of the two transmissions. Reversing the action of the solenoids corrects an otherwise incorrect signal, thus preventing the need for any mechanical alteration. I have explained all this umpteen times. You have accepted my corrections of your previous statements regarding the difference in solenoids. (Without any apology.) But even though at the time, I pointed out in exact detail, the reason for the change in solenoid, obviously you were unable to comprehend.

Re: US over to europan.
This would be an interesting experiment if it were being done by an SVX expert at their own expense. But we have several respected experts here all giving conflicting advice, arguing over the details and possibly pushing forward their own agendas. This helps nobody.
As far as I can tell, Alex doesn't have a full understanding of the gearbox internals, nor the proposals being discussed, nor of the many, sometimes heated, discussions that have taken place in the past. He just wants to get his car fixed. I really don't want to get involved in another flame war and I certainly don't want to take sides since I respect all the parties involved. Swapping the C solenoid and using a Euro TCU to drive a US transmission has never been attempted before. The computer program in the TCU that controls the gearbox was not designed for this and there is a good chance it will not work properly. If Alex is lucky then it may be drivable, but I strongly suspect that in some situations, the 4WD is not going to work as designed. Putting a US transmission into a European car has been done before. A uk owner did it some years ago. He fitted a US transmission, US rear diff, and US TCU. Some wiring changes were needed, but it worked. After driving the car for a while, he decided that the performance of the US trans was inferior to the European one and he sold the car and bought another. The modified car was bought by someone in Germany. I think this is a safer option than what is being proposed above. The parts are all designed to work together, the only changes are to the car's wiring loom for the VSS2 and atmospheric pressure sensor. But it's not a massive change. The wiring diagrams are already on the website. Plus, it's been done before, and proven to work. The absolute best option IMHO is to sell the US parts and obtain the correct Euro parts. Anything else will be substandard compared to the equipment originally fitted to this car. That's the last I'm going to say on the matter. I really wish Alex good luck in fixing his car and I hope it doesn't end up costing too much.

I agree it would be best to fit a US TCU but where is going to find someone who will be capable of doing the needed wiring changes and do it right? I personally would put it back to a VTD trans because they work much better than the US variant. All I am trying to do is get it so he has a car to drive and not worry about breaking the internals because of his binding issues. Tom |
