TH400 combo\'s? So what are the different years and combo's for TH400's? I have a 700R4 to a NP208 and was wondering if I could hook a TH400 to the NP208? I know they matched them up on a few years, but not sure what the spline counts are. I am looking at maybe going with a TH400 to my NP208 and then a NP205 until I can afford a doubler. Unless someone want to sell me a TH400 and NP205 combo !! <font color=red>BigBurb <font color=purple>IF YOU'RE SCARED, SAY YOU'RE SCARED !!
