ok so I'm running stock ECU in truck but I would like to know what I need to install to allow the 13 pin transmission to be able to work in my 2007 Chevy suburban with out having the vehicle trigger the p0717 code. Man whoever can help me accomplish this I'll venmo/cash app whoever 100 for gas or whatever. . Everyone that is trying to help me in my area literally think they know everything and it's so frustrating so I'm willing to help someone that will really help me . Out of respect. Just to let y'all know I'm mechanically inclined but I have never encountered a procedure along these line. So please and thank you if you can inform me the steps from A-Z . Breaking it down will really help me out and allow my family to have a vehicle. If anything I'll take this rebuilt transmission out and see if someone will trade this 13 pin 4l60-e rebuilt transmission for a rebuilt 15 pin 4l65-e which is the original transmission that was in vehicle. Please and thank you

6-speed you probably just need a valve-body and your original Techem or a new Techem and programming. I'm not really up on the 6L80 units.
4-speed
You don't really, there are to many changes to the 2009 plus units to go there.
If you were to try I believe you need at a minimum...
2009 & UP Valve Body, separator plate, wire harness, Internal mode switch and possibly a case. more than likely the parts needed to change it over will cost more than a core.

I Don't Think so!
However, for a 2003 4L60E Transmission replacement...
2001 - 2006 Cores are indeed what you are looking for.

New here and just started reviewing the thread. I realize it started out way back but see it has been updated by some knowledgeable transmission people. Hopefully someone can help. I have posed this question to lots of people with no clear answer. I have a 2012 Silverado 2wd, 4.8L and 4L60E 160k miles. RPO code is just M30. I know I could get it rebuilt but I think it was already an Aamco or something rebuild. It was making a nasty ticking sound. Will pull when cold. Been told it could be torque converter or front pump. I'm a salvage rebuilder and not going to keep this truck. I would like to just buy a lower mileage truck for the transmission and part the rest out.
My question.......... I see the 2009-2013 interchange. This is where I need help. What can it be from? I know 2wd but 4.3,4.8 only, 5.3 or??? Car part interchange shows two codes and 2CBD and 2LPD. My thought was the C would be for C series trucks? The L series states something about a TCM. Can anyone give me a definitive answer on what I should look for? Thanks.

Could you give me some help elaborating the 2009-2013 4L60E interchange? I have a 2012 Silverado 2wd, 4.8L and trying to figure out what used will work. 4.3 or 5.3? Mine has the D321 shift pattern. Will the DM pattern be compatible? Thanks

We Can't Help You without more Information!
You Talked about Possible Transmissions from a 4.3L Engine and a 5.3L Engine...
What years are these?
Are they Four-Wheel Drive?
There is a 4.3L Gen-I 90-Degree V6 Chevrolet Engine, and there also is a 4.3L Gen-V 90-Degree V6 Chevrolet Engine
There is a 5.3L Gen-III/ Gen-IV SBC Engine, and there is also a 5.3L Gen-V SBC Engine.
We should not have to WORK SO HARD/ TRY SO HARD to Help you.
Don't be LAZY and Obtain and Provide us with a Complete/ Full Set of Details/ Information.
Not to mention that Our Search Engine could have provided you with Access to Thousands of Posts with helpful Information!
It's actually insane how much Information is available there!
Let us Know the Details, and we will try to help you.
I will NOT make another Post where I do the Leg-Work for you, unless you first try and do it for yourself.

We understand that you have a 2012 Two-Wheel Drive 4L70E with a Bell-Housing for a 4.8L Gen-IV SBC Engine.

Trust me I have done a ton of leg work already!
I'm damn sure not lazy.......... It''s apparently not a 4L70e as per the vin. All I'm asking is what will work for an interchange in the truck. I've done tons of research to try and find out what will work. Car-part.com shows for interchange two different codes 2CBD or 2LPD. I would love to know the difference! Only info per the vin from the dealer is that it's a 4L60e. So???

just checking fitment I've made some notes above regarding the ELECTRONIC differences.
1993/1994 swap no problem
1995 one year only
1996-2006 electronically all the same
2007-2008 Added Input shaft speed sensor. These can be backward-swapped to 1996. The ISS will just be "ignored"
2009+ has ISS but eliminated the 3-2 solenoid. These can not be swapped backwards. 2007-2008 CAN be swapped up into the 2009+ because the 3-2 will just be "ignored"
All these notes do not account for input shaft/pump/stator changes.
Case changes for Neutral safety switch
2wd vs 4wd
etc
These notes are JUST for the electronic differences
With all of these noted...I can make any year core work with any year pcm. You just need to know what vb/pump changes/modifications need to be made. But...for any novice, you're better off finding a proper year compatible unit

Thanks. So if I’m in the correct year band you have above, they will connect up correctly? Does it matter if truck vs car, electrically?
Safe to assume 4L65e year bands above are similar?
For example, I’m wanting to go from an AWD 02 Escalade 65e trans to a RWD one and might have found a GTO 65e a few years newer in good shape. Hoping it bolts and plugs in, and all is well.

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.

1996 k1500 Ok so i have a 1996 k1500. 4x4 with a 5.7 and a 4l60.
i jist got my hands on a 2012 chevy exspress awd with a 5.3l and 4l60. If i understand this thread correctly i should be able to pull the transmission from the van and bolt it to th 5.7l.
My troubles will come in the form of electronics. So the question is can i use the factory harness from the truck and retune the computer. Or do i need the ls harness or a aftermarket controller to make function.
If i need a diffrent harnes. Recommendations on. Aftermarket vs stock ls harness. Also if you guys have reccomendations on tuners the have exsperiance in this i can buy a tune file off of.
eventually i plan on putting the 5.3 in place of the 5.7 but i dont have the time to build it till next winter on dont feel like doing it twice.
thanjs

A 2012 4L70E and a Vehicle that was Built as a "1996 k1500. 4x4 with a 5.7 and a 4l60e" are NOT compatible.
First the Transmission requires a Different External Wiring Harness, TCM and ECM (and Wiring Harness) that the Vehicle does not have.
Second a Gen-1 SBC 5.7L and a Gen-3/ 4 SBC 5.3L are not the exact same Engine Family and the Transmissions are NOT directly interchangeable
(Flex-Plate, Spacer, Torque-Converter are all different).
Please, do not waste your time doing all that just to install a USED Transmission that will probably not work, or die very quickly anyway.

Can someone please Lock out this Thread as ONLY people with incompatible swaps Post here who do not read what has already been posted.
Thank you.
