high clutch temps , every time i get into it hard
 

I'm getting a high clutch temp every time I hit the accelerator hard. I have all my gears , car seems to shift at a higher rpm than normal and hesitates between shifts sometimes. Due for a fluid change . I'm going to do that next week. But don't know if it's as simple as that. Any ideas ? 30000 miles , 700hp , ssp 800 transmission upgrade??know it has harden 1st gear , aluminum oil pan , trans and diff coolers, replace sensors about 1 year ago@20000 miles
