Got a used 02' T56 from Hawksthirdgen and since Ive put it in it WILL not go into 3rd or 5th gear. Let air getinto the hydraulic line so I bought new unit from him for another 160$. Same thing, no third or fifth... If a slave cylinder has a little air in the line, would that keep it from going into a couple of gears or all of them??? Maybe need to just keep bleeding the slave....
