ok. i got new engine in. runs like a top. now ive been fixing leaks as i go. the top of transmision i replacved orings. no more leaks. changed out the hydraulic filter up top. the one beside the trans. still getting pretty jerky hydraulic action. reverse is worse. gotta change lower filter today. is there an easy way to bleed air from the system? also filter light is on. it goes out at first then comes on. any ideas?
