Transmission cooler
J-mod (For the 99 and newer 4R70Ws go to www.crownvic.net, click tech
articles and click4R70W late model transmission upgrade)
3.73 gears and higher

I like the SCT Xcal 2, check around in your area to see what tuner different shops are using.

So what would be the difference in the J mod as opposed to firming up the shifts with a tuner such as the Xcal2? is there a difference? can you do both or is one better than the other, anyone with experience from one or the other or both i would like to hear from?

obviously a tranny cooler is required if doing one of these. or i would hope that that would be an item on your shopping list when messing with an auto tranny.

Four things no automatic transmission should be without:

1. Shift kit such as the J-mod to firm up shifts
2. High stall torque converter 2600-3200 RPM
3. Transmission cooler
4. 4.10 gears

as was said above, as well as use Amsoil Mercon V fluid. also get the E150 pan. its a deeper sump and has a drain plug in it. heres the part number F8UZ-7A194-AA

also consider putting in an inline trans filter. when you do drop the pan, put in a new screen filter.

read the transmission articles at www.tccoa.com it will answer all of your questions

like everyone said, best thing is to go for a 2800+ stall converter, tranny cooler, J-mod and 4.10s.

With a tuner, you can undo the mod. And you can keep adjusting the shift firmness as many times as you want until you find the settings you like. With the jmod, you're done. Unless you crack the transmission open again and almost do the jmod all over again.

well if it's going to be a while for the J-mod then the tuner will do just fine because you can adjust until you find the setting you like

The Xcal2 has more adjustable settings for automatics than the Predator.

If it was me, I would do in this order:

1) J-mod and Tranny Cooler, flushed and refilled with Mercon V
2) Torque Converter
3) Handheld flasher unit

I did 3, then 1 without the jmod, then 2. Doing #3 first set me up when I got 4.10s and an offroad midpipe. I didn't need a SpeedCal or MIL Eliminators.

You forgot gears.....

cantslowdown...

If it's going to be a while until you get the Jmods, do this:

Trans cooler
Programmer and 4.10's (assumingyou're going to stay N/A)

Then you can do the T/C and the JMod once the tranny is all opened. No sense opening it up twice and filling fluid twice.
