A local shop built it. When my stock trans went I welded the clutches and didn’t have another vehicle. Mike said he couldn’t get me a trans for 3-4 months and I couldn’t have that much down time. It’s a gmax 6-3 kit raybestos clutches. Tim Hecker who’s a big duramax sled puller taught my builder how to build them. It has never given me any issues so far, I’ve got about 35-40k miles on the build and no billet. I’m sure it’s gonna have to come out for a refresh and billet at some point.
I seen what your talking about though but it looked to me like converter lockup? I need to get a switch, the tuning and lockup isnt as consistent as I would like.
