Orig TCM was an JG unit . which was broken by a mechanic trying to remove it . i replaced it with a HT and match the software with 4F1910155G_HT_20. the gearbox was then sent for repairs . after repairs the clutch seem not to engauge in both drive and reverse . there is no fault code generated also . i then tries a second HT tcm with the same result . Eventually another gearbox was bought for the car from . i placed the tcm in the replacement transmission and i get the same thing . the engine revs but no engaugement of clutches in reverse or drive . i cannot do any sort of adaptation also .. I realy need some advice on how to proceed with this . currently i am awaiting the orig tcm to read it with pcmflash .

Can you please help me with TCM file for Audi A6 2.7 4f5910157h file to write with pcm flash, my unit was changed and I don't have original TCM hence having error P1841
You need 4F2927155D for Hardware 01J927156HT as SGO file.
Your 01J927156JK is not compatible to use it on this car. Even for PCM flashing.
I can help you only on public forums. My support is always for free! I do not reply to PM's !

Hello Gearbox expert. Hope you can help me with a problem.
I have the following.
4F2910155P HW: 01J927156JG can you please convert this to HW: 01J927156HT
Good afternoon. I have a problem with my SEAT EXEO 2.0 TDI CR. The VL300 01J927156HT CVT control unit has failed. I found the exact same part number (01J927156HT), but with different software from Audi. Could you help me with a dump that would work with the immobilizer disabled? The firmware number is 8E4910156P__0020.sgo
