Ive been planning on switching to a reverse pattern manual vb in my th350 for a while now and im finally getting to doing it. What Ive read is they are pretty harsh between shifts at part throttle and even though my car is primarily a track car I still like to cruise it around. Ive read a few threads about guys leaving the modulator in place and it substantially helped the 1-2 shift at part throttle. Is there anything you have to do special when installing the new vb if you want to keep the modulator or just leave it in place?
