Will a built 04 Lb7 tranny fit in my 05 LLY

[Duramax King]

Hey guys like the title says will a built 04 Lb7 transmission fit into my 2005 LLY and will I run into any problems with this setup down the road?

Yes and No. Yes it will bolt in but it may need the valvebody changed. In 2004 they release the transmission without the "G" solenoid then during production that year they added the "G" solenoid in . So if the built transmission has the "G" solenoid on it your set.
