Well, whaddya know. We usually don't find out about new products, features, etc., until there's one in for service and we have to learn real quick.

[Valsport]

Info - New Product Announcement - 4L70-E (M70) Automatic Transmission #05-07-30-026 - (Oct 7, 2005)

 

2006 Chevrolet Silverado, TrailBlazer SS

 

2006 GMC Sierra

 

with 4L70-E Automatic Transmission (RPO M70)

 

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

 

Important: The following graphic and table describe only the essential components that make up the M70 transmission model and will not identify all parts.

 

 

 

 

 

 

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