Jet product
I'm looking at a Jet Power Shift Transmission tuner for my E-350 V-10 with the 4R100 transmission.I don't really feel like spending $400 on a Superchip tuner as my main complaint is with the soft shifts of the tranny.This product costs $120 and I'm tempted to try it at that price.It gives you 4 different shift settings and doesn't require any physical changes to the tranny.It connects to the wire harness and appears to be removable if I had to for service through Ford.(I have almost 4 years left on Ext warranty)I can't find any feedback on this product online so if anyone has experience with this product I would appreciate any opinion you might have.Thanks

Personally, I think controlling line-pressure electronically is not a good as doing it mechanically, like a valve body or separator plate.
But that's just my two cents.
Many folks have great luck doing it electronically via a chip.
For what it's worth, I've got an Art Carr valve body, plus a lot of engine mods (inlcuding a blower so I'm really taxing my tranny) and a custom tune. My tuner didn't put any shifting changes into my tune.
I've got 130K miles, tow a 7,000+ lb. boat regularly through the desert, and have had zero issues. But I'm certain you'll find others who do it via a chip, with similar reliability.

May I recommend you take a look at either a valve-body or a separator plate?
Here's one good place to look for info. There are also others...

.I just found out on a different thread that this Jet PowerShift product won't help in regard to my 4R100's reluctance to downshift which is my biggest issue with my drivetrain.
