I recently swamped my tranny too - it was like draining chocolate milk out of it when the pan came down - the tranny was rebuilt with Heavy duty bands and a shift kit. The also plugged the stupid breather behind the torque converter and plumbed one up on top. $2800 over all at Aamco - shifts like a mustang now - its pretty crazy! They also added a heavy duty tranny cooler.
