modding an automatic?

Alright, Ive heard good and bad things about the auto's in the powerstrokes, and mine is an auto and Im worried if I mod this truck too much itll break. Should I be worried? the truck has 173K miles and the previous owner said it was recently serviced, but he didnt go into details about it.

and all the guy use the truck for was to do stuff on his farm. Should I? I was just planning on getting a air intake, chip/tuner, and exhaust and gauges. should I do just these or go further and not worry about the tranny?

One of the most popular tranny mods is the Sonnax valve and Tricumulator springs. They work together to make the tranny shift firmer and quicker with less slippage. It takes away the mushy, soft, can't hardly feel it shift, stock shifts and makes it shift real nice. I have the valve and springs in my tranny and am pleased with how they make it shift.

Freak, the torque converters in the earlier PSDs are pretty weak. See if the previous owner had it replaced or not, with that many miles the original converter is probably on borrowed time.

I was thinking that the TC was slipping a bit when Id put my foot in it, other then that it does ok. would a chip/tuner help any?

how much are those valves and springs and how hard of an install are they?

A chip will only make your converter worse, might as well bite the bullet and get an aftermarket converter, especially if you plan on many mods. Never done the Sonnax valve and spring but I hear it's a fairly simple mod. Dieselinnovations.com sells the kit and has the instructions on the site.

The valve and springs are a simple install. Noticable difference in shifts, worth the money and time invested. They give great instructions, easy to follow and well detailed.
Just might want to let the transmission fluid cool a little bit before you try and change it. I was driving it for a while, pulled it in the shop, drained it and went to work on it. It makes it a little more difficult when the oil is burning you as it drips off the transmission.

haha, I hate doing stuff like that on hot cars. Once I pulled my GT into the base hobby shop to swap radiators. I didnt give it any cool down time, just went right to work on it. Well when I loosened the radiator hose clamp, it was under so much pressure the hose shot off the radiator and fluid went EVERYWHERE

Also, would mods like exhaust and air intake hurt the truck? stupid question I know, but this is my DD and my mustang was my DD and I modded it and now it sits on the street not running! lol I need this truck to run every time I start it, but at the same time the mod bug is bitting me in the *** and I want to mod it a little

I wouldn't think exhaust and an air intake would hurt the daily performance of the truck in anyway, it should help it, it'll breath a lot better, both air in and kicking exhaust out.

You should be fine with an intake and exhaust. I'd want to be real careful going with a big chip on your rig though. The trans. is the weak link in these trucks and if you think your converter is already slipping....well what more can I say.
