trans leak

My 01 voyager was involved in a minor fender bender on the front end still driveable. concrete pole was hit by van just inside dr side headlight. The van has developed a trans leak right below the dr side of the radiator,ac condenser,trans cooler. All 3 were shoved back about 2-3 iinches and bumper re-enforcement was bent back and flattened out. My question is how do I get to the location to fix the leak. Everywhere I look there seems to be no room. I know I need to replace bumper re-enforment and filler pad and headlight.
