I am thinking about replacing my c 4-dana 20 with a c 6-np 205 combo. The only worry I have is, how much power I will lose. Right now I love the power of my jeep, it has a 89 5.0 ho fuel injected mustang motor. If I lose a lot of power is there anything I can do to the transmission to gain back some power. I have heard I will lose about 40-60 horse power.
