1990 Sr5 Shifting Issue

[pyro1453]

I recently had a tranny put in it has around 30grand on it and it also has a new clutch. I ajusted the pedal and still it seems to be hard to shift in to first/reverse and i dont see what else it could be.I cannot find any leaks in the master or slave cylinder, any ideas or things to try would be very appreciated.
