Back in June I yanked out the pcs solenoid for the trans go vacuum modulator (found it cheap on ebay). Has worked like a charm until recently. It has developed a shudder from 1st to 2nd gear. Factory diagnostic says its a line pressure issue(too low?). Gears disengage (like going into neutral) when backing off heavy throttle then light throttle. Anyone else have these issues?
