400 kickdown - The 1947 - Present Chevrolet & GMC Truck Message Board Network

If I understand you correctly, if I use the kit, 2nd gear will kick in at a later RPM. The kickdown will also be enabled at a later RPM. So, right now, my kickdown is inop at over 2000RPM in normal cruising. The kit should let me increase this RPM range. This will have to wait until I change my rearend. I will talk to Summitt or B&M when I am ready. Thanks for the help. Just reread your post, it only changes at WOT?? Not at cruising in 3rd gear, then going to WOT, because you are already in 3rd, right?? But if you are in 2nd, it will hold 2nd longer before it shifts into 3rd. Any suggestions on getting it to downshift at 2000RPM + w/o doing it manually??
