Hello! I have a 1994 Toyota Landcruiser 80 series 1HZ diesel engine with only 111650km. It has a 5 speed manual H150F transmission. Now, the transmission is well known for its weak and defect 2nd gear synchros where you are unable to downshift.
My transmission probably needs a rebuild as it grinds on upshift unless I shove it quick but when cold it still does it. Downshift I have to double clutch.
I also have to double clutch into 3rd when cold and when hot I just need to slow down when shifting into 3rd as it will clash if quick. I can live with these two issues for now until it gets rebuild in the future.
Another issue I has was unable to shift into reverse when standstill sometimes unless I let go and press the clutch pedal again. Recently, it has gotten worse and unless I pump the pedal or step on it super quick and hard then I am able to get into reverse with no issues. 1st gear on a standstill is also not the smoothest.
Also, the clutch pedal sometimes feel easier to press and sometimes it is harder (which is normal since its unboosted) and generally weird feel but it does return fully. And I have noticed all the gear change now are not as smooth now.
There is a very slight sleep at the clutch master reservoir and accumulator but I have flush the old nasty fluid with brand new dot 3 fluid and bled it properly. Fluid level also does not go down.
Is this a sign of worn clutch master cylinder and leaking internally? I have also taken the pictures above the clutch pedal for your take on it.
I did also check the clutch flexible hose and squeeze the clutch slave cylinder boot to check for any fluid leak and there are none.

Back that old. I'd replace the master in the slave. And of course if that didn't fix it, then you're going to have to pull the tranny and replace the clutch assembly
