Can the modulator seal be replaced without pulling the transmission or exhaust. I believe this is what is leaking and not my pan gasket as previously thought.

the modulator is on the drivers side. you are looking at the servos on the passenger side. the rear servo can be done in the car, the front i've only done out of the car. to do the rear servo for the 1st time, i would remove the exhaust and drop the trans mount. gives you more room. and replace both seals on the cover. small 1 in the top, i think. good luck, chuck.
