Front pump seal leak

You will need to remove the transmission and then re-install it which is about 5 hours of labor. Then, once the transmission is out, you will need to replace the front pump seal and bushing. The bushing is very important because as it wears out, it usually causes the torque converter to have too much play which wears out the seal. Also check the torque converter shaft to make sure that it isn't worn out and damaged. The seal is about $20 dollars and the bushing is about $40. The labor for the bench work on the transmission is about 1 hour as it requires specialized pullers and drivers. So say $600 labor and $100 parts plus fluid so $750 is about right if there are no other complications.
