Does it do it when cold or hot? Also the best oil to use is full synthetic trans oil which means you must flush it cause you can't mix oils, synthetic oil withstands much higher temps but it sure as hell sounds like the clutches, does it take long to go in to reverse after being in drive? That's also an indicator of worn clutches
