My 2001 pontiac sunfire will not shift into overdrive. The previous owners replaced the transmission, and it still will not shift into overdrive. It tops out around 50 mph at 4k-5k rpm. If anyone can help me diagnose this problem i would greatly appreciate it.

So my '99 Sunfire was leaking tranny fluid and coolant. We checked to see if I blew a head gasket but there was no coolant in the oil. We changed the radiator and now my check engine light is on and if shifts really hard. There is also tranny #2 in the car. Anyone have any advice on what I should do/change??
