So after having my built trans tore down finally it came out with a busted input drum. So what is the usual upgrade to the stock one? That trans lasted 6 months and it was done. So for it looks like a kit on the factory one or break down and order the sonnax drum thats suppose to be a lot better. Will be going back in the truck in my sig with a 3200 stall.

So

circle d kit $150
sonnax kit $50
or sonnax drum $500

 

I broke that on my old truck aswell, My builder guranteed his transmission would hold for my power levels and it didnt, he replaced it with a billet one free of charge, cant remember the name but it last 2 years up until I sold it, believe its still going strong
