i tried searching, i searched under diffrences between a b16 and b18 transmissions, i searched under b16 and b18 all kinds of stuff

so i was hoping someone could point out the differences between say a itr trans and a 99 up si b16 trans

as far as i know its the lsd and i think 5 gear but im not sure

thanks alot


eric

Well they are both 5 speed if that's what you meant by that.

for B18C5 and B16A2 transmissions the only difference is the B18C5 has LSD. The gear ratios and final drive are the same.

96-97 JDM ITR transmissions are the same as above. Only the 98+ JDM ITR transmission is different with a 4.785 final drive.

 

98 abd above jdm itr tannys also have a taller 4th and ffth gear

 

Older B16 trannys had smaller differential housings (ie: you could not fit an ITR LSD into a B16A1 tranny w/o modification), but around 95 or 96 (someone will know the exact year) the differential housings were changed to that of a B18 sized housing. Could have happened when the civics went from SiR-1 to SiR-2.

Other than that, the rest of the facts have been said already.

 

LSD only difference

 

thanks guys

 

don't ITR trannys have double or carbon Syncros?

 

no they dont

No carbon, just double cone (only second gear)

yes....

b18b
b18c1
b18c
b18c5
b16a
b16b
b20b
b20z
all can use the same clutch flywheel

b18a tranny depends on the number of splines on the inputshaft

 

all are interchangeable except the 90-91 tranny's cuz the have different spline counts

First GEN JDM B16a trannies YOU MUST COUNT SPLINES!!
they mix'd and match'd that tranny!!!

 

Don't forget, some B16 trannies in the 92-95 SiR's came with an LSD as an option.
