4l60e replacement a friend just replaced his 4l60e in a trailblazer. he needs to know if their is any computer 'pairing' or syncing to be done with the replacement trans. he is using his valve body and internal harness t as the plugs were destroyed in the junkyard trans. the trans came out of a 07. his is a 04.
thanks.

done a little reading and i bet he doesnt need to do anything. he called and asked. i dont know a thing about chevy trans. i assume its like ford, where it has solenoids for gears and lockup. and a controlled pressure relief for modulation. he did follow the internetz and youtube for swapping parts to include grease to hold check valves.
please let me know if i advised him wrong. this is his second trans swap. he assumed that he needed a toon for a trans swap. i told him NO.
thanks again.

No tunning needed but there may be some parts interchangeability problems with the 04 valve body on the 07 trans. If it's installed already, try it, it may work. If not installed, I would do some research on swapping valve bodies. I am no expert on parts interchangeability.

The VIN Input Process and a Shift-Adapt Procedure should be Performed.
Also, regarding Swapping between different 4L60E/ 65E/ 70E/ 75E Family Model-Years:
Also, regarding Swapping between different 4L60E/ 65E/ 70E/ 75E Family Model-Years:
The 4L60E "Electronics" differ, and are Model-Year Dependent (and in some cases Sub-Model Dependent)...
As well as physical/ Mechanical changes/ differences over the 1993 through 2013+ Production run.
The Breakdown is as follows:
4L60E productions runs for model year interchangeability are:
-1993 only
-1994 only
-1995 only
-1996 - 2000
-2001 - 2006
-2007 - 2008
-2009 - 2013/ 2014
Note: 4x4 4l60e units are not a direct swap with 2 wheel drive units...
Also different Engine Families use different:
-Bell-Housings.
-Flex-Plates.
-Flex-Plate to Crankshaft Flange Spacers.
-Torque-Converters.
-Pumps/ Stator Supports.
-Input-Shafts/ Turbine-Shafts.
Electronics differ...
The PCM, External Wiring, Internal Wiring (including Electrical Connectors) and Internal Components, all change/ differ.
All of which makes Swapping from different Applications more complicated than it needs to be.
That being said, making those Swaps are possible, and have been done TONs of times.
However, I would not bother with that type of swap.
The 4L60E/ 4L65E/ 4L70E/ 4L75E Transmission Family, is the MOST PRODUCED 4-Speed Automatic Over-Drive (RWD) Transmission EVER, in the WORLD!
So there are plenty out there, that are a Perfect Match for your Original Transmission.
Good Luck!

2007 Internal Harness has an Electrical Connector with 2 Terminals that are NOT going to MATE with a 2004 External Harness.
See my Electrical Connector Thread, Post #6 in the Hyper-Link below:

I told you People (meaning Members)...
I know that My Electrical Connector THREAD is HUGE and MASSIVELY BORING...
But it is DAMN helpful!
