thinkin i got trans problems
 

i have a suncoast tranny and i was pullin a load of christmas trees the other day and my truck wasnt pullin like usual, my truck was screamin but not movin like usual, didnt feel like power was gettin to the ground, feels like not enough pressure on converter or i was thinkin maybe some electrical, tranny wasnt hot, didnt get over 160, fluids looks fine, but when i wasnt pullin i could get it to brake loose goin down the road around 45mph, it was fine before we put a set of stage 2 injectors and now this, just wanna know any ideas?
