My wife's '95 Voyager (3.0L, 4 spd auto) has started making a groaning noise when accelerating from a dead stop. If you accelerate VERY gently, it doesn't do it. If you accelerate normally, it does do it. Oh, and it doesn't seem to do it when the van is cold. The van has about 119,000 miles. The transmission was rebuilt about 5 years ago, and last had the fluid and filter changed in the early spring.
Other than that noise, the transmission seems fine. The fluid looks and smells good, and it shifts smoothly and quickly.
I took it to the dealer here today. I got the "they all do that". Funny, I don't recall it doing this before. The mechanic said that what we're hearing is the transmission bleeding off pressure when you accelerate from a stop so that it doesn't peel the clutch material off. Is this right??? Does this make a noise you can hear???
