EPC control I have a 2001 Tahoe 5.3 and matching year 2001 4L60E transmission LS swapping to a 1989 K5 Blazer.
I want to convert the dual plug throttle body that came on it (2001/2002 DBW style ) to the 2003+ single plug throttle body.
I have the stock 2001 Tahoe 411 ECM RED/BLUE.
The 4L60E has been completely rebuilt. It obviously uses the 99-2002 EPC control.
Will swapping to the newer single plug DBW throttle body, harness and ECM cause shifting issues since the 2003+ ECM is looking for the 2003+ trans? Would I need to purchase all new 2003 EPC setup?
Is this programmable in HP Tuners?
Thank you to anyone that can help.

They are different, Manufacturer & Connector....But functionally the same.
The early Holley made EPC is actually a better piece than the later Borg Warner EPC.
Yes, All other solenoids are compatible.
