anybody have any input on John Wood's valve body for a stock E4OD? mainly looking to tighten up the shifts and get a little better performance out of the trans along with some custom tunes. thanks!
I would recommend it. I have one in my e40d and it used to kind of slide into overdrive but now I have no more of that along with fast firm shifting. It’s definitely worth the money in my book. I also use the stock and an added trans cooler because I haul heavy rvs every day.
thats exactly why i am interested. im tired of the typical looong e4od shifts. i really like how the JW or even BTS vb changes the shifts to nice, short, firm shifts
