rebuilt transaxle, trans works perfect until driven or warmed up near 15 to 20 min. has a squack when making a 2-3 shift w/hot. also w/ hot engagment from park to od (makes same noise) w/ park to rev (makes same noise). i have itback apart on bench w/no finds on problem area.sounds like a internal fluid leak but no suspect area. hoping someone else has been here. thanks
