I would like my truck to shift a little bit later than it does. And, the TV cable is adjusted right. There is no slack in it but it still shifts early. Under light throttle it shifts at tround 1100-1150 rpms. I would like for it to hold until at least 1500-1600 rpms. So, I came across this: http://www.sonnax.com/part_summary.php?id=4786&pl=1.

Anyone actually installed one of these? Did it work like the description says and were you happy with the results? How difficult was the install? I am also open to suggestions. I don't really have the extra cash right now for a fully built valve body from one of the big vendors. I can pick this kit up at a local dealer for $40. Thanks!

 

the sonnax stuff is all top shelf and they also have a real good tech department
if you are mechanically inclined buy the shift kit and install it yourself there is a company called a and reds transmission and they are regular guys I bought a deep trans pan with the cooling fins from them and I want to say they are having a special on them right now the go to guy is rob in parts he will guide you with wht you need to do I believe all the hot rod valve body guys are doing is installing shift /reprogramming kits you boost line pressure fix the drain back issue and they give you a new manual valve in some of them talk to rob for the best one he is honest tell him Tim from connecticut told you to call for him
