Can you guys help me figure out a parts list to build the strongest 4L60E possible?
The trans is a 2006 4x4 unit, rcsb, 383ls i already have my Circle D multi disk 258mm 3400 stall converter, thanks for your help!

I would start with lookin at the sponsers

 

5 pinion planetaries, Raybestous or Red Alto Clutches, Kolene Steels, Transgo or Ratio Tek shift kit, Corvette servo or billet servo. Kevlar band, boost valves. Beast sunshell .

Just off the Top of my head.

 

How much do you have to spend?

I choose a stock 4l80e over a "built" transmission. I could not swallow being stranded by a multi thousand dollar transmission.

But if i was going with a built one i would go with FLT or performabuilt. They have the best track records here.

 

Every thing they put in FLT's level 7, im sure they also have some secret personal touches they do.

 

Lots of nice ideas here.
