i have a 5sp and have never owned an auto,ive decided to trade up to a longbox dually from my shortbox,i have found a beatiful dually with very low miles but its an auto,will an stock auto hold a comp or a smarty?i have both on my 5sp and i want to keep them.also has anyone done a auto to manual swap?is it as hard as im thinking it would be?pedals,hydraylics,driveshafts etcetc.thanx

I considered the swap too but since theres not to many wrecked CTDs in our area parts are very expensive. It looked like the conversion would cost the same as building a trick auto so... as to your question will a stock auto hold a smarty or a comp, I never had a smarty but the comp you can get away with for awhile if you use your head to control the fuel.

Basically the stock auto will hold about 40-50hp over stock for a while. A shift kit or valve body will help increase pressures and help a lot. But if you're really working it, you will need an upgraded trans.

Autos are like women... All basically the same but some are hign maintenance

Now that I've offended some.... Factory trannies vary greatly in strength and durability. Most will hold an EZ or a Smarty... with reasonable driving habits.

With just a Valve Body replacement ($400-500) you can have a great driving truck that should handle up to 375 hp!

what valve bosy does one have to buy? and where?

what do i need to hold up to 450 hp? is a valve bosy and torque converter enough?

If you get a built trans. by one of the 4-5 venders you can read about here , then I think and have read that the autos are stonger than man.

I've got a biult Goerends and it's holding the mods in my sig just fine.

Mines held 500hp + for quite a while with a tripple disk TC and a valve body. I dont tender foot it either.

I've been holding 398hp for a few months with just a VB but it started slipping on me in OD the other day.
