forgive if this is the wrong place:
If I purchase the LB7 Duramax Diesel ECM - Stream S-LB7. LBZ Duramax Diesel ECM - Stream S-LBZ and LLY Duramax Diesel ECM - Stream S-LLY, do I get the capability of tuning the transmissions also, or are they divorced so I have to pay for the trans streams separately?
Thanks!
