Does the tranny of an LX sedan 89 is the same as an SI or it's more as an DX ? What are the gear ratio of this 89 LX tranny ?

 

The dx and lx transmissions are the same. They are not as aggressively geared as the Si transmission is.

 

Do you know how much i can get for an 89 lx tranny (top shape) with clutch and flywhell ?

 

Trans shouldn't be more than 250 bucks for a quality one and that is even a lot. The L3 transmissions are quite plentiful since alot of people are doing b series swaps. Are you looking for a new clutch and flywheel? A new clutch can range from 150 for a low end clutch all the way up to 500 bucks. A new flywheel ie clutchmasters, act, etc are around 300-400 bucks.
