they guy says the tranny was out of a 94 ex but my 1st gear goes to like 39 mph instead of 35 and when i take off i have to rev it alot higher and it shudders to take off
it says S20 on the tranny like my old one but i dono.

All the 92-95 Civic trannies are S20. The numbers afterwards on the sticker are of now use. You must look above the tranny drain plug to get info. Look under "Basic Info" on the link above.

FYI info, 7200 rpm in EX----DX----CX/VX
in first gear = 35.2----36.9----46.0 mph

The easiest way to tell if you have a CX/VX tranny is 3rd gear.......
you can do 120+ mph in 3rd gear!
