Ok so I have the turbo 350 trans,bnm shifter,so my mechanic said this is 3 speed and I didn't know the p/o had it setup so I could only go park ,neutral, reverse ,drive I didn't know there was 3 more gears, if he was apparently racing this car wouldn't he want to use them to shift at higher rpms I'm confused?

 

When you put the transmission in drive it will automatically go through all 3 gears.

Also why is this in the cooling section and not the transmission section?

 

The gear selection for a TH350 (turbo 350) goes as follows: P-R-N-D-2-1

When in D (3rd), as stated before it will shift through all gears starting in 1st, etc. It uses a vacuum system to shift gears.

I've never heard of someone preventing it from being able to be shifted into the lower gears though. Does it literally not pull down past D (3rd)?

yeah, wrong section. Mods will move it hopefully

 

The thread says transmission so I posted but I took these underneath so they mite b upside down is that the right alum.chrome box and shouldn't there be a cover for the flywheel?

 

I'm not sure what you mean by "the right alum. chrome box"

There doesn't have to be a cover for the flywheel, that part is called a dust cover. They can be purchased though if you want one. I personally don't have one.

 

I was jw is that shiny metal box in the pic a trans cover

 

Are you asking about the oil pan?

 

In the first pic you posted the shiny metal box is the oil pan on your engine. The transmission pan is the more square-flat box behind the flexplate (it's not called a flywheel on automatics, forgot to correct that in the first post)
