tranny leak i think
 

i have a 1987 420 sel i had a tranny tune up done three months ago and it leak for a week i added a quart or fluid and it didnt leak for the two months i drove it for . i parked it and let it sit for a month the other day when i moved it i noticed some fluid and the same when i moved it once again two days later. what could be the cause thanks joe

if many miles,probably the front pump seal.will usually leak from the bell housing area when left sitting.

david the car has 145000 miles on it but when i moved it i only backed it up 10ft
