Replaced my trans mission now the car runs rough, how do I go about programming my cars vin onto the new transmission? TIA

Programming the VIN into the trans will not make the car run any better.

You have to be more descriptive...are you seeing a CEL? Getting any codes? Mods? Did you change any other parts out when swapping the trans, etc.

Before trans was replaced car was running fine it has no mods

Are all your connectors plugged back in? Did you do the replacement or a shop did it? The trans won't cause the issues you are describing. Sounds like something is unplugged or wires got pinched.

You will have to ref lash the new transmissision,they have different parameters,and shiftpionts,it's worth i,it may not shift right ,runing your new trans.

Thought the same, supposedly everything is plugged in, a shop did the swap.

I did try to flash it with the vin using winfkp, did the alpina b3 flash

Appears electrical-related if you're 100% sure everything is plugged in correctly and the car was running fine before the transmission was replaced. Damaged harness, blown fuse(s) or relays, or (hopefully not) a damaged DME. Perhaps the shop shorted out something and blew one of the large 30A fuses in the DME circuit. I'd start by checking every fuse in the DME box and then the fuse panels in the trunk and behind the glove box.

So, you did the swap and then immediately flashed Alpina before driving it? Did the new trans ever drive correctly before flashing?

You keep adding details to the story that should have been mentioned in the OP.

That's the only thing I could think of as wondering conformation,if you did swap trans,is programming nessasery being that even tho,the trans is behind a 335or 535, it would still have to be vin programmed,wouldn't it? I don't think it's a direct bolt in. Did you notice any changes before flash?

Car was running fine before the swap, I eventually took it to the dealer they checked the timing and it was fine, now they saying that the ecu needs to be replaced, I replaced the relay by the ecu and fuses were fine, the code for relay didn't came back but car ran the same...

I got the ecu today from the dealer and 2 of the mosfets are bad, the ones for Cyl 2 and 3, the weird part is that I'm only getting codes for both camshaft sensor, cps and for the throttle no codes for misfire or 30bb..

Swap was done and when the car was started that's when problems emerged, I did the flash and it was still the same..
