So I pulled my 1999 Civic Coupe Ex D16y8 Transmission.

1. The 1 1/2 thick plate thing with teeth spins regardless of what gear I click it into by turning the little **** with a flat head etc.. Is that normal?

2. Is there anything else I should to the transmission to check if its ok or in good condition or something? Basically a light maintaince test,

 

1:that's the flywheel unless im getting confused by your post.

2:? did you just pull the tranny for fun ?. Rear main seal.TOB,isb,

 

This Is just one problem of out of a few that I have to solve. The auto shifter would not go into reverse or park only neutral drive and 2 or watever.And I think it may be the torque converter I'm talking about. It connects to the flex plate with 8 screws.

 

ok that's probably it. lol should have said that in your OP. looks like I don't even know the basics now.

 

Its auto matic

 

Might want to give the backstory on how your transmission came to be in the condition it is.
