Hello i have a 99 civic auto. something is wrong with my trans when i take it out of park and slams into gear and when i put it in D4 it seems as if the trans is stuck in like 3rd gear. I have already swapped the trans for a different auto trans and I'm still having the same problem. This trans came with it own lock up and shift solenoid. Before this i have not had any problems with my trans. I was getting off the freeway and stopped at a light and went to take off and been stuck ever since . Just need some advice I'm at a complete loss especially with putting a diff trans on the car and still having the same issues.. Thank you all in advance
