Why isn't my tranny going into gear after replacement?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If you've replaced the transmission and it's still not going into gear, but the grinding noise is gone, the issue might not have been the transmission itself. It could be a problem with the torque converter, the linkage, or the transmission control module (TCM). If the torque converter wasn’t seated properly when installed, or if it’s not engaging with the transmission input shaft, the vehicle won't move, even though the grinding noise stopped. Also, double-check the shift linkage to ensure it's correctly aligned. A misaligned or improperly connected linkage can prevent the transmission from shifting into gear, even though everything else looks good. Finally, a TCM or electronic issue could be preventing the transmission from engaging, so checking for any stored trouble codes might help.
