i think when i still had my crx hf tranny(with a bad bearing) and im going 70 mph on the highway my rpms in fifth gear were about 1k rpms or so.

ever since i changed out my tranny im getting 3k rpms in 5th gear going 70 mph.

so did i get a ex/si tranny instead of an hf?

 

si

 

ya, i get 60mph (100km/h) @ 3,000rpm. Due to slight variances in tire size, speedometer accuracy, id say you got an Si tranny for sure.

what's the code on your tranny? i need to know for one i just picked up.

 

from what i read i got the smaller bearing tranny and that would signify a dx, hf. but im getting 3000rpm at 70 mph...so thats confusing me. im running 185/65 or 60/13

 

I have 300 ~65 in my dx

 

from your tire size, it would appear to be a DX

 

but my civic ex runs at the same rpm and its only an inch bigger on the rim size. shouldnt make that much of a difference would it?

Rim size doesn't matter, it's overall diameter including tire. 13 inch with 65 is just as wide as 14 with 55, adleast I think (crosses fingers that he can still talk to tire talk).

 

EDIT: **** i lied man, i must have left them in my apartment at school Sry


If you want new bushings I think i have a set sitting in my basement
PM me and i'll let them go real cheap

 

Hmm, 3k at 70 is about the same as my automatic. It must be the same as an Si, I think I'll just leave it!

Tire sizes do not affect speedometer/tachometer reading ratios. They only affect actual ground speed vs. indicated speed.

i am gonna have to agree. IIRC the HF axle wont even fit right into an Si trans

Yes it will. All '88-91 USDM axles are the same on the transmission end. The difference is at the hub end.

ah! thank you for the correction

 

is there any way to tell besides "what your rpms are at a given speed" and taking the transmission apart (the code on the tranny it self)?

some of the older trannies dont have numbers on them, or they had stickers which, by now are mostly worn off.

well, if it did still have a sticker, which mine does, and it starts with "SL3", what tranny is that?

SL3 is usually a 91 DX transmission - the SL3 tag is on the top of the case - not on front like other L3s

Sounds like a DX/LX tranny to me.
