About 2 months ago my c4 stop shifting into 2nd gear so i pull the line off the.modulator and transmission fulid was coming out, so i.said ok the modulator is bad so i put it off until today i ordered a green stripe one and put it in.and same results, the line is not bad that goes to it to the intake but i noticed on the old modulator the screw in the middle is adjusted futher than the new one..does my problem sound like i need to adjust it or something else...and i did fill the transmission back up fulid
