As far as what I've looked into, your platforms are straight forward and easy swaps. As I recall ( I didn't do in depth research as those platforms are pretty much 6L80 ready) the key components are the TCM harness, transmission tailhousing and new driveshaft yoke. I believe I've seen a few threads of people converting over GMT900's already.

 

Any word on the Kit?

 

I can understand it would be awesome behind some < 500 rwhp trucks but there isnt much aftermarket for these yet. id be willing to bet a built 65 would last longer but that is all speculation .

a built 4l80e will be a better choice until the aftermarket steps up to support more hp through the 80. a 6 speed would kick *** though. but the high hp guys will still be stuck with the 4 speed for now.

 

Subscribed, this could be perfect for my future setup.

 

im interested, if my transmission goes out again id be willing to spend the money for this swap

 

Definately interested...

 

Sorry for lack of update. We had a brief moment of success. Then our prototype module was shorting out so we lost some time having new ones made then once we put it in we had a module fail in the transmission. One of the issues of buying a used transmission over a year ago and not testing it until it's installed. It's back at the dealer and I've 'strongly' encouraged them to have it done by this weekend.

 

I'm in for this. I think thats what is lacking in my truck. I chose the older gmt 800 because I'm in love with quadraster, but the 4l65 hides the power this truck has.

 

 

any news?
