2005 Yukon Denali motor and Tran swap 2007 Yukon Denali

[Cv610]

I have a 2005 Yukon Denali. I was going to buy a 07 Yukon Denali needs a motor and trans. Will my motor and trans fit in the 07 Yukon Denali without issue ?

I can't advise about your engine swap, but I moved this thread from the 2021+ section. Your thread covers two different body styles so I picked this one.

Welcome to the Forum from NH.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

Your question deals with the compatibility (or not) between the NBS platform and the NNBS platform. I'm not an expert in this, so I'll leave it to other members of this Forum to answer your question with some authority. My 'guess' is that they are not compatible and would require some work to force compatibility.

have a 2005 Yukon Denali.

Which came with a 6.0L, and a 4L60E.

was going to buy a 07 Yukon Denali, that needs a motor and trans.
Will my motor and trans fit in the '07 Yukon Denali without issue?

Physically, yes, duh.
Every GM 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L is the exact same size externally (well known fact since '99).
6L80E is a lil bit larger than a 4L60E, so switching to a smaller trans should be easy.
PHYSICALLY. In terms of pcm vs ecm / tcm ...
If the '07 Denali came with a 6L80E, good luck making the 4L60E work with a tcm that expects a 6L80E.
I'm sure it's doable, likely involves using a wiring harness from a NON-Denali GMT900 vehicle?

If the '07 Denali came with a 4L60E, congratulations, you lucked out.

Some of the sensors on the gen 3(99-06) are in different locations than the gen 4. The 2 different years use different reluctor wheels on the crankshaft so youll need some type of signal converter and a extended wiring harness

Do some internet searching of the show “Trucks” S3 Abandoned Chevy Silverado Project: On the Road Again.

They pulled a NBS LS 5.3 & 4L60 out of a Burb to install in an OBS Chevy pick up

They used an Edelbrock ProFlow 4 TCU set up mate the later TCU into the earlier truck. Watch the first 2-3 episodes so you can get grounded on what’s needed and available for swaps between the OBS, NBS & NNBS chassis.
