for 4L80E and 4L60E.. i like the overdrive and rather not go to 3 speed or less. auto/electronics gotta stay.. have 408 camaro ss. may do 475-500 to the tires and maybe 150-200 shot of nitrous.. 4L60E is what i have now. just wanted future references. thanks.

 

look at one of the sponsors, FLT.

 

Go with a level 4 4l80e from FLT, not the cheapest but it will handle over 1000 hp and still have od.
