I can't find a straight answer. Are 4L60E's interchangeable between vehicles? Can I use one from a corvette in an S10, or an S10 in a silverado? Or a suburban with 4x4 in a camaro (minus the transfer case)?

 

NO!
First, 2WD and 4WD are not interchangeable as they have different output shafts and it takes an extensive disassembly to swap output shafts.
Next, you have incompatible 298mm and 300mm input shafts.
Most LS engine vehicles have the 300mm input shaft; the exception is the C5 Vette which has a 298mm input shaft.
Next, '93, '94 and '95 are odd-ball years that only work with a PCM from the same year.
Next, some '05 and all '06+ have an Input Speed Sensor (ISS); if your TCM expects ISS, you absolutely must have a trans with it as it cannot be tuned out.
However, pre '05 PCM/TCM can use a '05-'08 ISS trans because they ignore the ISS signal.
Next, '09 and later have an incompatible valve body and wiring harness connector.

In short, assuming you want to use it in a Camaro with an LS engine, you need a '98 - '08 4L60E/4L65E/4L70E from a 2WD vehicle with an LS engine, except for C5 Vette.
The best indicator of the 300mm input shaft trans is a bell-housing bolt hole in the 12 O'Clock position.

If a picture is worth a thousand words, or however many I wrote above, you need a 300mm trans which looks like this:

 

Perfect, thanks for the information. But I'm looking for a new trans for my 1998 Suburban 1500 with 4WD.

So I'm guessing I can use a 4WD trans from non-LS vehicles with the 298mm input shaft? Can I use trans from 96-08? S10's, Blazers, Tahoes, Suburbans, Yukons, etc should all work?

 

I don't know non-LS vehicles very well, but I believe the answer to both of your questions is Yes. The 4WD case will have the shorter output shaft and the bell housing will not have a bolt hole in the 12 O'Clock position.

A 298mm input shaft 4L60E for non-LS vehicles looks like this:

 

I realize this is a big bump and hugely off-topic, but I've asked all over the internet without a satisfactory response and I figured the people on this forum would know better than anywhere else.

I have a 2000 s10 (2.2, 4x2) with a bad 4l60e that I need to replace and I'm trying to replace it with the newest model possible since it's easier to find newer transmissions with fewer miles. I already found a 2008, would a 2008 4l60e fit in my truck or are the electronics different?

Someone earlier in the thread mentioned that a 2008 would work behind a 2000 LS1 so I was hoping the same would be true for an S10.

 

All the same as what you read above applies for input shafts, etc

as for electronics the 2008 will have an input speed sensor in the pump...you won't use it...it's fine to leave it unused. Won't hurt a thing.
in 03 the EPC changed from GM. the pressure vs amperage tables in the PCM changed also...In my opinion it wasn't any significant change where it would cause any damage, but you could always replace the EPC with an early model and use an adapter plug if you want to be extra sure.

 

 

Did you even read the thread above?

Make sure you have the right bellhousing and input shaft before you buy one.

 

Instead of switching the EPC could I instead just have the PCM reflashed to reflect the new changes to the EPC?

 

Yes you could. it's really minor difference, but the tables are different.

 

The trailblazer and envoy I6 are the only non LS vehicles with a 300mm input shaft. So the '98 blazer trans won't work. A 5.3 trans will but you have to put your bellhousing on it.

 

 

It won't bolt right up. The converter pilot is too short, bellhousing is different.

 

 

Do people really need a spoon fed "yes" or "no" for every single question they ask?

mrvedit did great work compiling the differences above in this thread and others. you CAN MAKE any 60e work with any engine and any ecu control.
people always say that 95 was a 1 year trans and nothing interchanges with it...they are correct that you can't just bolt up a 97 trans and go down the road...but I can modify it to make it work.
You can swap input shafts, use crank spacers and different flexplates, etc and make just about anything work if you want to.

245 input shaft bolted up to a 5.3...yep...you can make it work if you really want to.

read the stickies also. They usually have the answer you need.

https://ls1tech.com/forums/automatic...s1-4l60-e.html

the 4.3 should have the 298 input shaft. That means you will need to use a different flexplate and converter with an LS series engine.

If you read the 2 threads I linked...it will tell you that it's probably better worth your time to just get the proper trans rather than deal with mis-matched parts and swapping

 

 

There are two main styles of 4L60E:
* The "LS" style with the 300mm input shaft and deeper (removable) bell housing; the converter has a longer pilot. Nearly all LS engines that came with a 4L60E have the "LS" style. (The C5 Corvette is the exception).
* The "LT" style with the (differently shaped) 298mm input shaft. All pre '99 4L60E are LT style. Nearly all non-LS engine vehicles that came with a 4L60E are LT style. (Jays_SSZ28 mentioned a few exceptions.)

There is also a 245mm input shaft version, but I think it was only on older 6-cylinder vehicles.

Even when the trans is bolted to an engine, you can tell its an LS-style 4L60E by the bolt in the top 12 O'Clock position.
Note: There is no way to tell a 4L60E from a 4L65E from a 4L70E by looking at the outside.

As mentioned, unless you want to become a trans expert, it is best to replace a 4L60E with the same "LS" or "LT" style as what is being replaced.

 

 

Does anyone know if a 4L60e transmission from a 2002 k1500 4x4 will work in my 2003 gmc envoy 4L60e .. I’m having issues , it does do anything ...

 

no mention of the engine in front of either trans
no mention if either is 2wd or 4wd
This thread went from being very helpful to just sad. brand new users (fukucachme has 3 posts) reviving dead threads just to be spoon fed info they can't search for themselves.


If the truck is v8 and the envoy is i6 then it will work, you will just need to swap bellhousings.
if one is 2wd and the other is 4wd then you'll need a total teardown to change the output shaft...in which case you should just fix the trans that isn't working
