emperorbrownsuga Posted July 15, 2011 Report Share Posted July 15, 2011 Basically I have the same common problem with the 3.1 head gasket blown and debating possibilites and ease of swap the whole 3.1 sub frame with a lumina LTZ or similar subframe. Anyone have an idea if both subframes have the same bolt pattern and mount locations? Yes i am aware of the wiring and ECM differences. However, would the 3.1 tranny controller work on the 3.8 tranny? thanks appreciated. Quote Link to comment Share on other sites More sharing options...
AL Posted July 15, 2011 Report Share Posted July 15, 2011 There isnt a separate trans controller, its all in the PCM Quote Link to comment Share on other sites More sharing options...

If you are going to swap you have to take it all. Quote Link to comment Share on other sites More sharing options...
kuntzie Posted July 16, 2011 Report Share Posted July 16, 2011 the subframes are the same, and IIC the 99s all had the 4t65s at that point Quote Link to comment Share on other sites More sharing options...

Yep, Just get the PCM with the wiring harness and youll be all set Quote Link to comment Share on other sites More sharing options...
