Has anyone used them and if you have used them how about some input on them.

I have pictures just need to find out how to post them.

Are you sure it's not 5? 4 is stock and 5 is aftermarket. People who have them usually get them with an extreme trans build up so it would be hard to say what they do by themselves. Are you going to be opening up the trans just to put the planets in and nothing else?

 

I found a new set of 6 Yes 6 pinion front and rear planets and just got the story on them. G.M. produced 10 sets of billet 6 pinion planets for testing and to develop the 4L65-E but the six pinion had to much spin loss for fuel economy people. The planets are a prototype part and I don't want to try untested parts so I will use 5 pinion planets in my next trans.
