sonnax for 99 V-10

[greenscapes]

I have a 99 V-10 that I was thinking about putting in a banks transcommand, and then I got thinging about the sonnax that I have heard people putting in. What it the difference and do they make one for my V-10? Thanks for the help

The transcommand will raise the line pressure, not always a good idea. The Sonnax valve/springs will shorten the shift duration and firm up the "hit", my vote is for the later. The pan must be dropped and accumulator body removed to do so, but I feel it is a better mod.

Does anyone know if I can get a sonnax for my V-10 and does it have the same transmission as a diesel? Thanks for your help. Also for those who have installed them, how is it? I get intimidated with transmission stuff like that.

Yes the Sonnex will fit the V10 tranny (4R100). It is an easy but messy mod. Should take an hour to do. Think about adding these too:http://www.techtranstool.com/tric.html With the springs and Sonnex it will shift really firm.
