My Taurus 1997 with DOHC 3.0 L 24V has its tranny rebuilt but now the tranny can´t shift rom 1st gear no matter the speed I accelerate. Reverse is OK. I replaced TRS and TPS with no results. Speedometer is working fine, so it doesn´t seem to be a VSS issue. ATF is new and in right level. Any ideas to help me out with this problem? Tks.
