Opinions on trans build.

Dana knows his stuff. He builds a lot for the Impala SS crowd (4L60e behind 4200lb modded cars that RUN), as well as others. He uses Trans-Go kits with specific instructions, among other things. I'd trust his input.

Yeah that's a kit ...

after talking to the builder, the sonnax is better then the average shift kit, instead of just changing springs, it modifies the valves..or something..lol its been a couple hours since i talked to him and have forgotten.

we talked for nearly an hour when ordering all the parts....I couldnt remember what was what. just that the parts sent will make the truck very happy.

Got the trans out and apart over the weekend. 3-4 clutchs and low/rev clutches were on their way out. Everything else looked good. We got 90% of it back together, but didn't have time to do the valve body or pump upgrades, but should be finished this week. Trans didn't look like it was rebuilt previously, but couldn't say for certain either way.


Also what are you guys doing about the gaskets for the extention housing, couldn't find replacements, gasket sealant?

GM 1358899 Original Equipment OEM Seal

I think I have that one, what about the one from extention to transfer case?
