vb or shift kit?

[panteramatt]

Im looking into installing either a valve body or shift kit in my 4r100 and need your guys opinions on which one and why. Brands and prices would help too.

Are you gonna replace the TC too while you got it out?? Or are you lookin at doin a sonnax type kit?? I vote full shift kit with new converter. The Transgo Tugger kit is plain ole awesome in these trannys.

[panteramatt]

No Im not replacing the torque convertor. I bought a used dp chip that was programmes for a bts tranny so basically I gotta get the line pressure increased and am wondering if its worth the $ for a valve body or maybe the sonnax kit for $45?

i went with a john woods, putting it in next week, heard good things about his VB's

Is there a big difference between the vb and the sonnax kit?

Neither one does ANYTHING to improve the output of the front pump. I went the sonnax route, and for a while, it "covered up" what I was trying to fix.
