SHOULD THE MODULATOR BE ADJUSTED AFTER ...
1989 Buick Lesabre
Should the modulator be adjusted after replacing like the instructions say. Now after the second shift it almost seems to down shift but it's not going out of second gear

No, it is preset. The shifting may be throttle pressure adjustment.
