you have internal trans issues. you need a trans shop to track it down and give you a bid. it most likely will have to come out and be overhauled.

You most likley have a shattered 3-5 reverse clutch waved plate. It is the weak point on this transmission.The trans will need to be removed and torn down for an inspection.
