my wife has a 92 sedan. i swapped out the d15b7 and automatic tranny for a jdm d15b and auto tranny from hmotors. i have replaced every hose under the hood with gates hoses. brand new radiator, headgasket, and waterpump. i replaced the thermostat 6 times and now im running it without a thermostat. it runs great until you drive up a steep hill. it starts to overheat. im thinking its a problem with the tranny. it has honda atf in it and it is topped off. it shifts so smooth and gives me no problems. does anyone have any idea why the car would get hot going up steep hills?

Have you thoroughly bled the cooling system? Otherwise, the head gasket job may have gone wrong.

----------------

Bleeding the cooling system may take 20-30 minutes:

1) Park the car on an inclined driveway with the front end higher than the rear.

2) Push the dash heater lever/**** to MAX heat.

3) Follow the directions in the diagram below (hint: the bleed bolt is located where the upper radiator hose connects to the engine):

i bled the coolant correctly. why do you say headgasket? i hope thats not what it is lol i dont want to do that again. how would the headgasket make it overheat going up steep hills?

The increased engine load may worsen a small leak in the head gasket. You may want to do a cylinder leak down test and also pressure test the cooling system.
