Rebuilt the 2004R in my 1989 Olds Custom Cruiser. When I shift into reverse I get a buzzing or rattle kind of sound from the trans. When I pull the TV cable all the way out in park I get the same sound. I put a pressure gauge on it today and did some driving around. Pressures seem to be about where they should be. Pressure readings are smooth when driving with the exception of in reverse. When in reverse the pressure fluctuates wildly. I get the same wild pressure fluctuations with it in park if I pull out the TV cable while running. Seems like maybe a pressure regulation or valvebody issue?? Any hints on where to look first are much appreciated. Thanks, Chris
One last detail, the car did sit quit a bit for the last 6 months. Just started driving it again about a week ago.
