Transmission clunks when shifting, already had it replaced twice

Did you check the coupling between the drive shaft and the tranny for wear? (universal joint) Have someone in the car and lay on ground nearby so you can see the universal joint when they put it in gear. DO NOT lay under car when they put it in gear!

A/c workd but wont change different speeds and wont shut off even when you turn off truck you have to pull fuse and put in to run

this sounds like a bad fan speed resistor may have shorted and works only on one speed with or without the key on. there maybe a code in the BCM module that may help find the problem.
