    Finished J-mod on `04

    No kit required. Just follow those instructions. You just enlarge a few holes in the separator plate, remove a couple springs in the accumulators. The J-mod is a procedure developed by one of the engineers responsible for the design of the transmission. It works well and will not cause damage...

    Finished J-mod on `04

    Click on the link above that I posted. Best simplified instructions that I could find. Later models like yours don't need as many modifications as earlier models because some of the changes were already made by Ford. It's not a kit. Just modifications made to the valve body and accumulators.

    Car Sputters After Gas Station Fill

    Try fueling up without filling. Add to maybe 3/4 tank. If it doesn't act up, somehow the evap system is drawing in fuel when the tank is full. If it still acts up, there's likely dirt in the tank that's churned up when you fuel up, and it's being drawn into the fuel pump pickup. After the car...

    I need more speed!

    Could be even as simple as a plugged fuel filter. But sounds like you're hitting a speed limiter.

    I need more speed!

    I read a similar post somewhere else. Turned out the car was a rental unit originally, and had a speed limiter that couldn't be overriden.

    Tuner Help *Diablo Tuner*

    If you're loading the factory horsepower tune, (87 octane) you can't modify it, unless you've got the latest revision. But it you update your predator, you won't be able to dissable the rear o2 sensors.

    If emissions testing isn't an issue, an off road x-pipe is definatley a good power mod.

    Stang drifts to the right

    Did they do a 4 wheel alignment? Even though the rear isn't adjustable, it can be out of alignment and cause dog tracking. Something in the rear could be loose or bent and it will cause the car to pull or drift to one side.

    Problems with starting

    Make sure also that your tank has gas in it. Your gauge could be wrong and you could be running out of gas.

    Oil Change Problem

    There should be a seal on the drain plug. If you're a little over full don't worry. I almost always over fill my vehicles for over 30 years without issues. If your cars on an angle when changing oil, you might leave a little bit of old oil in the pan, but if you change oil at regular intervals...

    Good NA setup??

    If you're going to do all that engine work, plus nos I'd recommend rods and pistons as well. Every guy i know with a PI 4.6 that has run nos has burnt pistons or blown the intake to bits with a backfire. What a waste of work and money that would be. I know there are others that have run nos...

    Pilot Bearing Ruined! Need help!!

    As a last resort. The outer ring is hardened and brittle. You can use a hammer and chisel to break it and then just pull the pieces out. Don't wail on it and be careful not to damage the crankshaft.

    Pinging on SCT tunes

    Did you clean the inside contact areas on the battery clamps? The contact areas on the battery posts and the clamps should be shiny, to make sure you get good contact. You might want to try a different gas station. After changing to a different supplier, it might take a while before you see any...

    4R70W question

    Mine does it, but it's only noticeable when holding first manually, and light to medium throttle. Don't worry about it.

    Pinging on SCT tunes

    12.45 volts is not a fully charged battery by any means. You're tuner is not likely why your car won't start. Your battery could be bad, or you might just have poor battery connections for that matter. if it won't crank, and you pats light isn't flashing, your tune has nothing to do with it...

    Low Beam Headlights Stopped working?

    You wouldn't believe how often it's just that both bulbs are burnt out. It's easy not to notice one bulb burnt out. Seriously, try a new bulb.

    Drive Cycle Issues

    Code p0455 is a large leak in the evap system. New cap might be defective or the cap was never leaking in the first place. It's possible the cat effiency test might not run if a leak in the evap system is detected. Unfortunately testing for evap system leaks is not something easy to do for the...

    Shift override?

    I think he's talking about the shift interlock. I don't think there is an override button but the console trim around the shifter does pull of really easy and I'd bet the lock mechanism could be accessed from there.

    Drive Cycle Issues

    Generally the evap system self tests run only after a cold start, and the fuel level must be correct as well, around 1/2 a tank. The cat self test, usually runs during steady speed cruise. Hope that helps.
