Thinking of lifting my truck and swapping the 6l80 for a 4l80. At some point the truck will see 800whp probably very soon. Only want 2-3" lift but need to know what brand kit or what parts will be needed to hanle 800whp. This is a daily driver.

Also searching for a how to thread or a parts list for the 6l80/4l80 swap. I would like to have a very accurate cost estimation so I can decide on swapping or getting a buil 6l80. I know guys have done the swap just cant find any detailed info on it.

09 crew cab 4x4. Thanks for any advice rebuilt engine going in soon and would like to do everything all at once.

Any recommendations on who to buy a built 4l80 from? Im leaning towards Jakes but open to suggestions. Also anybody have a complete parts list of everything needed to make the swap?

U will need a 4l80e yoke, tuning, crossmember mod, transcooler line extended for rear. For a 6l80e u will most likely have to get some type of conversion box for the harness. the 6l80e tcm is built into the trans. If u cant get a conversion harness u will need a harness from same yr truck with 60e trans and a e38 ecm. Retune and segment swap for 80e trans.
