I just had a shift kit, servo, and aluminum accumlator piston installed. Still, once the D1 is back on I dont expect it to last very long. I dont want to get too far into it though under warranty.
Technically it is all bolt ons

I have not yet blown mine but I am also over due.

Tune isn't the greatest I'm guessing. I'm seeing almost 8* of KR at WOT, either due to the noisy valve train or false knock. I may do one more mail order tune from Wester's. Just need a mod first. I'm holding out on doing my own tunes to see how the EFILive 7.2 vs HP Tuners 2.0 matchup turns out.
I console myself on the dyno numbers due to the TC and bigger tires. I'm running 8.8 verses 10.2 in the eighth between motor swaps, so something went right.

I've owned my truck for about 30K of the 62K miles on it. I drive like a bat out of hell almost always. Never had an issue. The Radix was just installed, only made a few runs down the street but it still feels real firm. Time will tell.....

im at 87000 now with my stock transmission and i have had a shift kit in it for about 25000. got a cam and every other bolt on out there and its still doing good except for changing into 3rd its wanting to slip a little so im just running on borrowed time i guess.anybody know a cheap place to get tranny parts on the net?

I'd guess not much either. Both of my 60's started slipping going into third, then they wouldn't go in 3rd at all at WOT. Then they'd start slipping bad in 4th and 4th would go completely away. Then third gear would go quickly after that(within hours) 
If you baby it you can get lots more miles outta it but, if you continue like normal(like I did
) it'll be gone within the month I'd guess. Damn 4L60E's

BTW, driving in second gear on the highway is fun, everyone thinks you want to race them cause you stay tached up around 4000+rpm. Trucks REAL responsive up there.
