My 95 is doing the same thing. After a lil research, i found out it is the End Clutch.

It is only $89, and takes you 30-45 min to do it yourself, i plan on doing it here soon when i get the money. Ive read that kit will also prevent it from happening again in the future. Im pretty sure if you take it to a Transmission shop, they will prob tell you that its shot, need to replace/rebuild and charge you $4000. Also, replace your tranny fluid/filter while your at it, thats what i plan to do.
