Who cares about break in? Those of us who would like to keep the trans bolted to the back of the 5.9 for the next 100k

Just as a side note, a 3850 FB DD can be on a daily driver. I was worried about using one until I tried it. I think it is easier to drive than the FE it replaced. Heck my wife used the truck for a month or two (taking kids to school, etc) while the Excursion was tore apart.

Wow, I get back and all of the sudden there's 20 posts. Thanks for all the input, sadly I will have to break it in for while I guess I'll find a quick way to put 1k on it....road trip!

I wasn't clear about what I meant also. I can wait to do a boosted launch, but with the stock clutch I couldn't go WOT even with the Comp off, just the new injectors did it. I should be fine if I leave the box off and no launches, but I can goose it right?

i drove mine for about 300miles normally, even had some 5th and 6th gear blasts at WOT but nothing with power shifts, or slipping launches.
the next time i filled the truck up on my way home i did a 3500rpm 3rd gear launch and it never missed a beat, and to this day doesnt slip. I even had a really bad pull this year where i rode it too long with the sled behind me, and for about 3 weeks it was hard to get into gear...and now it drives and holds just fine again.
whenever is starts getting too jumpy i just do a small 3rd gear launch to get it warm...and its smooth as butter for another few weeks or so before it gets grabby again

When I install new brake pads, I've always got them hot first time out to get them seated to the new rotors. If I don't they always pulsate when towing heavy. I've always done the same on clutches too. When I had my clutch put in at ADT, I drove it around for 500 miles & noticed that it was super jumpy while pulling out from a stop, never got better. I pulled one sled & noticed that it wasn't grabby like before & smoother to engage. These things need to get hot to break in. I understand if you guys don't want to do this to a $1700 clutch & I didn't either, but after seeing how much better it got after some launches....I would launch it. Just my nonsense.

My first clutch was from Kenny's pullin parts. It was a 3800 ceramic button dual disk. Even with SBC hydro upgrade, wouldnt go into gear worth a hoot. Kenny told me to hook and get it broke in and seated. Didnt believe it at first, but worked like a charm. I did rebuild after little over a year, but i did it voluntarilly. Numerous sled pulls and 3rd gear burnouts will tend to tear things up. Bye the way, when i pull, rev to 3500 r's, start slipping clutch and when boost hits anything over 40lbs, dump clutch and drop the hammer.
