I have an 1987 300zx that has an automatic transmission that I recently changed the transmission Filter and encountered a problem with. One Bolt that I loosend and took out by hand would not go back in at all! I sub a shorter standard bolt to seal the hole to keep the fluid in place. This bolt I removed was attached to something internally I think, But would not thread back into whatever that something is. The bolt is a 10mm and different from the other 2 blots that holds the transmission filter on.

Can anyone tell me what this bolt attaches to internal, and how I re-attachet it. My cars jumping or somthing like something about to give out whenever I start to take off from a complete stop, otherwise it shifts fine while driving. Any Suggestions would be of help.

Thank you..
