Does anyone know if the 4l60e's in the 4.3, 4.8, and 5.3 are different or are they the same? Thanks, Michael.

 

VERY DIFFERENT!!! The 4.3 still used the old style input shaft and 298mm converter. 4.8/5.3/6.0 engines used the "LS1" style input shaft and 300mm Converter (which makes the stator shaft different as well).

 

Another question for you. Can the LS1 4l60e handle the LQ9 6.0L?

 

You would be suprised what a 4L60-E can handle. Most of the failures I see are NOT "Torque" induced. Sometimes its an inherent flaw (i.e. Reaction Sunshell) and sometimes its just a parts failure, not caused from too much power.

 

wow! So you dont need to step up to the 4l80 then. However, it would be correct to say that the LQ9 would be pushing the 4l60 right?

Also, I plan on getting the 4.8L engine. Do you know if the 5.3 and 4.8 use the same 4l60? I ultimately down the road plan on dropping in the LQ9. Thanks, Michael.
