well i just got a 1994 jeep grand 4x4 all time , larado for 500$ well 2 things wrong with ti one is the a/c wont work , i turn it on max the ac clutch wotn kit on i checked the low side pressure it is at 40 any ideas how to diagnose the problem also i was driving it and from a stop if you hit the gas the trans makes a sound and feels like hardly no power but when i hit 25 it drives fine well thanks again

 

If at 40 with compressor off there is not enough charge to turn on the clutch.

You may need a new governor solenoid in the trans. Sounds like it is taking off in 2nd. Pretty common issue. Google 42re governor
