Yes, the case is the same, the only different is some beefier parts inside and the NEW (07+ i believe) 60/65/70 have an additional speed sensor.

Yes however the 70E is not stronger than the 60e, The notation 70e simply means it has and input speed sensor where the 60/65e does not . When a 70e is placed in a 60/65e vehicle there is no wiring for the input speed sensor so its ignored , however you cannot replace the 70e with the 60e because those trucks require the speed sensor. You can of course swap the pump /input shaft and harness to do it but what would be the point

A 4L70 is a 4L65e with an input speed sensor. So yes a 4L70 is stonger then a 60, it has 5 pinion planets, hardened input and output shafts, and 7 3-4 clutches.

A 70E does not mean it has an input sensor. Where do you guys get this? The 60/65/70E all have the input sensor now. The 70E is a 65E with a different output shaft. You won't find a 70E behind a 5.3L or 4.8L, but you will find a 4L60E with an input speed sensor.

From bulletin: 05-07-30-026

General Motors Powertrain required a version of a current production rear wheel drive transmission capable of handling higher torque and horsepower without going to a larger size transmission. As a result, the 4L70-E was created. Very much like the 4L65-E, the 4L70-E shares many of the same components and adding premium materials and additional manufacturing processes, the 4L70-E is capable of handling up to 400 horsepower and 430 foot-pounds of torque. It is also capable of increasing shift speeds up to 6000 rpm.

The 4L70-E will be first introduced in some 2006 mid-size sport utilities and full-size pickups. The 4L70-E will be identified as RPO M70. The M70 will use the large 300 mm (101K or 112K) torque converter. Some M70 models will be the first 4L60 series transmissions to receive the new input speed sensor (ISS) .

Below are the 2006 4L70-E applications and models:

• Sport Utility 4L70-E models with ISS: SKD/TKD

• Full-Size Pickup 4L70-E models: CMD, CWD & KMD



The following identifies the 4L70-E (M70) components and the components it shares with the 4L65-E (M32) transmission.

When we ask our core suppliers for one we have to ask for a 70e or we don't get and input speed sensor . I am aware that GM does make the 60e with the input speed sensor however. But calling it a 70e avoids lots of confusion.

We have torn down units with the 70 on them and found both 4 and 5 pin planets in stock units (Actually had our tear down guy bring that to my attention since I had told him all 70e were 5 pin I will say I have only seen two like that to date however) . Personally though I never thought the 65e was much stronger than the 60e to start with, The main failure we have seen over the past three years in trucks has been the breaking of the input drum or shaft and the stripping of the center splines in the rear planet and in these areas nothing was upgraded in the 65e over the 60e.
If GM was really out to upgrade the unit they would address those issues, I have seen no more failures with the 4 pin than the five so from my perspective it was not a significant upgrade, Have never really seen any substantial number of failures with the 4 pins as long as they had lube. And without that both planets will fail in short order.

I can see your point, but to actually call it a 70E because they don't know the difference just isn't right. It confuses others wanting the correct info. No offense meant, just trying to help get correct info out there. I'd be checking the codes on the trans from your supplier to see if they are really giving you what you ask for.


The 65E and 70E all should have 5 pinion planetaries. If they don't then you probably got an incorrect core. The 65E and 70E has held up to fairly big power in stock form with just a shift kit and converter change. The biggest improvement with the 5 pinion GM (not cheap aftermarket replacements) is the metal. They are a much higher quality than that 4 pinion version. The true GM one's are high quality and very, very rarely fail. The clutch sets in the 65E and 70E hold up much better than the 60E. I've never replaced a broken input shaft on the 65E and 70E due to them being hardened, but have replaced many broken drums where the shaft presses in. The 60E's I've replaced them for broken shafts and drums. I've also never replaced a sunshell in a 65E or 70E yet. The beast sunshell is very nice and I've never seen one of them break, but the 65E/70E one seems to be very strong also. The output shaft on the 65E is is hardened, but the 70E version is hardened with a different process and is even stronger. I have the info from another bulletin somewhere.
