I swapped out the b17a1 gsr cable trans. to put the og MINT b18a1 cable trans. back in and all the gears are very hard to shift into. The ls trans. has been sitting for over a yr. w/ minor rust where the axle goes in, so I sprayed that w/ wd40 and used Synchromesh for trans. fluid. I loosened the clutch cable and there was some relief, but it’s still not shifting like butter as it should. Any suggestions guys/gals, anything would help.
Did you get your flywheel machined? Once a machine shop screwed up my flywheel resurfacing and I couldn’t shift into gear at all, had to rev-match everything…
Instead of loosening the clutch cable, try tightening the cable. Pull up on the transmission clutch release arm (use a bit of muscle), and tighten the clutch cable adjusting nut. Sound to me like the clutch may still be engaged.
When my throwout bearing went out it stuck in gear. I’d say check the throwout bearing. Maybe it was reinstalled backwards (if that’s possible).
It is possible to install the throwout bearing backwards another thing where does the clutch start to grab at when you push the pedal? Does it grab higher up or does it grab when your foots closer to the floor.
Check your cable adjustment…id use the specified oil which is 10w 30 not that synchromesh…make sure there enough fluid…u sure all the forks and shift rails were attached correctly?
Yes it’s possible to install the throwout bearing backwards… But you’d have to be blind (or a complete idiot) to NOT notice it. Also the tabs on the bearing that are attached to the spring and release bracket would not fit.
Do not use engine oil… Although the oil weights would be the same, engine oil often contains detergents mixed in. Certain detergents and additives can actually harm the transmission in the long run. There are a few people on Honda tech who have documented the long term effects of engine oils vs. Honda MTF vs. Synchromesh, although I can’t find the thread (and who knows how reliable the information is…).
I recommend that you use OEM Honda MTF only. Several people say that GM synchromesh works and shows no adverse long term effect, but I cannot be certain since I have never used synchromesh in my transmissions before.
Our service manuals list 10w-30 as the recomended fluid, as Honda didn’t start making their own MTF until like '96. Motor oil will work, but as you mentioned, its advised to run genuine Honda MTF.
