WTB HF 5 speed transmission 84-87

Looking for a good functioning 1984-87 CRX HF 5-speed transmission or just a 5th gear seat from this model transmission. Located in central Pennsylvania, willing to pay shipping if further than reasonable driving distance.

i believe there is one in local junkyard
its definitely an hf...not sure if its pre-'88 or not
$50 to pull it plus purchase price and i'll meet you half way from columbus.
i've shipped many trannies and i know its $90 with packaging.
so meeting will save you for sure from mid-PA
agree and i'll go find out the year for sure

A Word of advice; The difference between a full Hf tranny and just an Si/Dx w/ HF 5th is staggering. HF tranny is incredibly tall (say 2k RPM at 60) the others with HF 5th is 2.8-3k at 60. The HF 5th only drops the 5th gear RPM 1-200 max. I've done it and was disappointed. Hold out for a full Hf if you want the super highway mileage. my .02, Mak

what he's referring to specifically is the difference in final drive
the si has a 4.25 final drive
the hf has a 3.25

there are other options if you are looking for a little mechanical advantage
right now i'm running a final drive out of a 96+ hx which has roughly a 3.77 FD
the 92-95 d15b7/b8 motored dx/lx models have a 4.058 FD

Will that 92-95 FD fit in a 84-87 tranny?

Actually, the "high-altitude" HF model is the one with the 3.25 final. The 49-state / or "low-altitude" HF is the one that actually has a 2.95 final drive. Pretty sick. The 2.95 is a super-sick tall-geared trans. This is why early EPA estimates show there being two HF's - one that gets 43/49, and one that gets 49/52. Yes, it's the 2.95 tranny that yields the 52MPG.

proof?
my understanding is that the 2.95 is an automatic transmission
i dont usually ever refer to automatic trans because they get less gas mileage
save the few who do not know how to properly drive economically with a stick
i get all my tranny info from mistabone (aka:transzex)
if you have never heard of him...then you dont know honda trannies at all

actually now that i think about it...the 2.95 might have been from the EW crx
the transmission is not compatible with 88+ d.series motors as far as i know

either way its one of the two scenarios last i remember...either auto or not compatible

well i guess you are right
only came in the 88 HF
and my bad, the HF only came in manual...no autos ever...
i guess its not swappable into a hydraulic z6/y8 tranny so i couldn't use it
which is why i wrote it off...
