I am looking at putting a supercharger on my '06 5.4 and I was wondering if anybody has had problems with their transmission not holding up under the extra power? I see a lot of Q&A about engine performance and how much boost it can handle, but I am afraid that the tranny will give up long before the engine.
i have a 06 also got about 1000miles on it. no problem thing runs better than before but if there is a weak link in the powertran the blower will find it how many miles do you have?
I only have 20k on the truck but I put a edge programmer on it at about 5k and I do drive it pretty hard. I just don't want to be setting on the side of the road kick myself in the rear a couple months after the install.
no i had a edge for like 10 k miles just hit 20k your truck is still pretty fresh. i would do it. its not like you got 50k on it or anything. o yea by the way i was at a gas station yesterday and a guy with the exact same truck as me color wheel and all told me thats what it looks like after 212,000 miles and al he did was a alternater so far. just something to think about.
I had 130,000 miles when I put my new engine in, I made it 15k miles running the u know what out of it... lost 2nd gear. now my tranny is bullet proof.
I installed mine at 50K and I am now at 89K and mine is still holding out ok.
I am how ever putting 489tq to the wheels so I dont expect mine to last much longer and I also tow a 6000lb boat. You should be fine installing a SC on your truck

I am suprised that it lasted 40k with that much power. How much money have you put into the engine to make those type numbers?
I have put in more than I wanted to. I had a injector go bad and caused me to run lean and I detonated in cylinder #4, after the motor was pulled we could of just replaced the plug and be on our way . So while it was apart I went ahead and added forged internals to crank out some real power. I have around 7K in the motor.
