There are two primary ways of telling them apart: RPO Codes – The 700R4 will be stamped with the code MD8, while the 4L60E will have the code M30 on it. If the transmission is still in the vehicle, check for the code label and you’ll find the stamp on there to tell you what transmission is actually in the car.
What is the difference between 4L60E transmission and a 700R4?
You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4.

- ALL 4L60E transmission have a 12 pin connector from the harness. They can be purple or green depending on the year
- They all are shifted by the vehicles ECM
- They all have aluminum cases
- No changes in gearing
What are some problems with 4L60E?
This is also a pretty common issue with the 4L60E. More than likely the reverse input snap ring has sheared or snapped off. It can also be caused by the sun shell breaking. The most common problem is probably going to be the low reverse clutch pack. The booster valve could also be an issue.
How can I tell if my transmission is a 700R4?
The easiest way to identify if you have a 700r4 is to raise your car and check the bolts around the transfer case.

What is 700R4 cable?
The 700R4 uses a cable that connects the throttle linkage to the transmission’s throttle valve (TV) in the valvebody. This is the governor that commands WOT up-shift speeds. It uses weights and springs just like a mechanical advance mechanism in a distributor, but employs two sets of weights for low and high speeds.
What is the advantage of a 4L60E transmission?
Shifting over to the 4L60E side, the main advantage of this transmission is that electronics eliminate the need for a TV cable and that whirling dervish of weights and springs to establish shift control. In the case of a retro-fitted 4L60E, a swapper will need the service of a separate transmission controller. Here is where both the main advantage and disadvantage of the electronic transmission reside. Separate controllers obviously add significantly to the overall transmission cost.
What is the advantage of a 700R4?
Another minor advantage for the 700R4 is that it offers an old-school speedometer cable, so upgrading an older chassis is simple.

700R4 and 4L60e Differences
- The biggest difference between these two transmissions is going to be the way that they are controlled. They identical in terms of length and where they bolt to the crossmember. The problem is that the 700R4 is controlled by the TV cable, which is basically just a basic throttle position sensor. The 4L60E, on the other hand, is controlled by comput...
Identification
- It is possible to confuse an early 4L60E with a 700R4, since they use the same transmission pan and are virtually identical on the outside. By 1996 though, GM began moving to the two piece case that they use for their transmissions to this day. So realistically, if you are looking to tell if it’s a 4L60E or 700R4 it’ll only be difficult for the extremely early ones. There are two in depth articles …
4L60e vs 700R4 Length
- Both transmissions are 27 3/4″ long overall, and both mount to the crossmember in the same location. This makes swapping them for one another physically no problem at all. Since they are the same length, you can even reuse the driveshaft. You should still try and find the transmission that was originally intended for your vehicle, since some are made to handle more power or diffe…
Swapping
- When swapping one of these transmission for each other, far and away the most difficult obstacle that you are going to face is how the transmission itself is controlled. With that in mind, from a cost perspective the 700R4 is cheaper to put in place of the 4L60E than vice versa. There’s a lot of good info about it in the LS swap transmission guide. Really, it’s better if you have a motor that a…
700R4 Versus 4L60e Strength
- These transmissions had a 25 year production life between the two of them. As far as which one is stronger from the factory, the 4L60E is stronger. They improved as time went on. So, it’s better to get a later 4L60E than an early one. The same holds true for the 700R4. Examples from the early nineties are much stronger than ones from the 80’s. If you end up buying either one from th…
Naming Confusion
- The naming of these transmission causes quite a bit of the confusion people have with these transmissions. A lot of people are confused by the 4L60 name. The 4L60 is the 700R4, just a later model. GM switched the transmission naming nomenclature to a more standardized format during the 700R4’s life. So the 4L60 means: 1. 4 forward gears 2. Longitudinal drive (rear wheel) …
