Does anyone know if I will have any problems bolting a 6.2 up to a 4L70e? I know I will be looking at performance issues with it once I start upgrading and I may even go to the 6L90e swap later but for now I just need to know will it bolt up and does anyone know of any definite problems I will have?

 

YES..... change flexplate... iamkeniff did that exact swap... he posted up in your other thread

 

I believe any of the LS/LQ or whatever will bolt up to xLxxE automatic transmission
Not to sure about PCMs...

 

i did the same swap first. i used the l92 flex plate. check your converter spacing .
