I love that there is another thread on here with people arguing just the opposite, that it can live I'd done right. Buncha haters!

 

Interesting read.
Those 6L80e transmission still need more time for someone to re engineer them and fix their flaws.
The 4L65E version took years before it was even possible.
Then again it may be wrong.
You just don't know.

 

Read this. I bought a lvl 3 rebuild kit from Jake's it cost me $1265 with his recalibration kit plus $300 for my core and it's proven to at least 1000 HP not just rated.

The only place on the face of this Earth I would trust to spend $$ on an automatic 4l60e/700R4 style transmission from is

That said, if he says the trans will handle 750FWHP then it will and that is also how I know the true, practical limit of that transmission, period.

 

That's pretty much what I have now.
I need more power handling for boost

 

Sorry for the late reply. It is on my C5z, and yes all comforts remain intact and un altered.
