new Kent Moore tool for GM trans

Attention transmission/GM guys I thought that I might pass this on.



Attached you will find photos of the inside of a Chevrolet Bell Housing with new Mortorq Fasteners which were identified on this 2007 Silverado P/U. These fasteners hold the bell housing to the transmission. If your customers are looking for the tool to remove and install these it is identified below.



Matco Part Number H6DT-49037-A Driver, Mortorq Spiral Fastener,

Description

Kent-Moore DT-49037-A Driver, Mortorq Spiral Fastener

Due to high torque requirements and difficulty in removal of the transmission case to converter housing bolts without stripping the internal torx, the bolt head is being changed to the new Mortorq design. This requires use of a special 3/8" drive bit that fits the propeller-shaped recessed design of the Mortorq bolt. Once the production change is completed, the Mortorq bolt will be the only one available from GMSPO for service part replacements.

A little background on this new type of fastener:

Mortorq®
The Mortorq Spiral Drive recess developed by Phillips, is much shallower than other standard recesses on the market, and can be put into a much shallower head without affecting the strength of the screw. This assembly allows for a shallower counterbore, reducing material thickness without compromising the joint strength, because it does not affect the material thickness below the counterbore. A Mortorq recess uses full wing contact with driver bit in both drive and removal directions.

Advantages and Disadvantages of Mortorq

Aerospace designers have had to compromise on fastener performance. Previously, shallow head styles had poor torque transfer and damaged easily while robust drives required thicker material and added weight. The unique shape provides full contact of the driver over the entire recess wing resulting in extremely high torque capability without the risk of damage. Depth of the recess in the fastener head is minimized resulting in true high performance in 100 degree flush head and shear head applications. The open recess concept allows driver to recess misalignment and compensates for paint build-up without degrading torque performance. Workers can easily install and remove panel and structure fasteners at odd angles without high muscle stress or fear of damage to surrounding surfaces. Larger driver cross-sections and curved surfaces provide extended tool life and resistance to tensile fatigue fracture when used with high load pulse tools.

I has those as I was work some of chevy vehicles at old job.. But now it is sitting in box.. Sometime it is better to have it than don't have it..

More tools to buy and I hate that.GM needs to go back to the one piece case and I hate the two piece case with a deep passion.One is the torque converter bolts can be a real PITA to get to with the two piece case.2006 and down have T50 Torx plus fastners holding the bellhousing on.I would pitch them in the garbage in put the T50 torx plus fasteners back in.
