from what i understand the guy (jerry) origionally designed a pretty good auto tranny, however, ford thought it was too agressive and tamed it down a bit by sizing down some of the holes, which is why our trannys feel a bit confused sometimes. The jmod puts it back to the origional specs.
total in parts it costs you like 15 bucks to do it, i havent done it, always wanted to but im hesitant to start monkeying around in there.
research the **** out of it, there are some bad instructions floating around, and more than one person jacked up thier transmission, but if you do it right apparently it makes a world of difference.

Swapping a valve body is very very simple. If you own an hanyes or chilton manual it has the direction on pulling it out i do beleive and its very simple. A tuner is the worst way to firm upo shifts as it makes the front pump work harder and will wear it down over time (been there done on that on my old F150). A valve body mod is a much better way to firm the shifts back up. There is a write up on this all over the internet aswell to show you how simple it is.

The jmod can be done for a few dollars in parts and then new fluid and filter. Its a must do for an auto car and you should add a tranny cooler to as heat kills auto trannys. Best $50 mod for an auto car is a tranny cooler.

Tranny coolers can be found on Summit, Jegs, Ebay, alot of sites. There's not really a certain one for Mustangs, just universal. http://store.summitracing.com/partde...5&autoview=sku

I don't believe the intake spacer for the split port upper will work with the Windstar upper.

If your going to be doing tranny work just do them both its easy to do a cooler, just mount it, unhook one line running out of the stock cooler from the radiator then connect it to the cooler hook the cooler line into the radiator and tighten claps, its that easy. The J-mod will take you if you have never done tranny work i would say around 3-4 hours taking your time looking at instructions etc.. over all both are easy and should be done to any auto car. Heat is the worst thing for an auto tranny minus neutral drops.
