Hi
Try to change fluid in gearbox and bleed.
After that do adaptation again. If it still fails that means TCM is dead.

I have make bleed, and after that car start but F still flashing again and P1735 is again present and no gear selection.

it seems you have open wire in transmission control module TCM ... but you need good soldering skill ... check that first , if you see open wire solder it ... erase codes and reset the module .

I dont think it was wiring problem. As I said before this error P1735 appared when I try to make Learn Point Adaption. Before that car start and work fine but during reverse R engaged I heard a noise, so i decided to bleed and to make a gear learning for better performance. But after that I have this error P1735 and car not crank and no gear engaged.

On p1735 you have 2 burned mosfets on the pcb. Open the case and you will see buk7614 blown.
Another problem might be the clutch wheel is thin and addaptation cannot touch the correct points.

Thanks for your help. I havent mosfet burned because as I said before calibration car work, anyway I have open ECU and test every mosfet and they are not burned. But about clutch wheel maybe you have right, maybe this is the reason for this error.

I want to ask if this problem can solved with eprom recalibration or not any experience

Read again...

What to repair in dump? Maybe write adaptation points by hand?
Change the clutch and adapt it!

Problem solved. For all members, error P1735 the only solution is to learn gear by diagnostic. I do that with Delphi Diagnostic China, it done perfectly. So I solve my problem.

TCM Programmierung Opel DIMITRI.jpgVery simple. You can do it with Vaux-com or OP-COm. Just make automatic learn and follow instructions on screen. I have learn it from a guy from youtube.
