4runner_Jeff

Greetings all, I have a 1990 4wd 4runner, 3VZE, with a 5spd... and 295, 000 miles on it (new heads at 274, 000 due to a burnt exhaust valve on #6).
Recently (past week) I have been having some shifting issues that came to a head today... On Monday I drove it on the highway for a while and when I made my way to city traffic the shifting became clunky.... seemed like things might not be lining up.... and on one occassion I could not get it into any gear and at todays culmination the clutch pedal sank to the floor with no rebound.... pumped it a bit and it came back....getting home was an adventure..
On Monday afternoon I checked the clutch master cylinder reservior and it was lower than it should be...below "E".... but still a bit of fluid in the bottom of the reservoir (little plastic orb. looking thing was not floating)... topped it off but noticed that the fluid that was in there was pretty dark.
It is good to go if it is in gear (no slippage)... which would lead me to think that the clutch itself is ok... but that there is something going on with the master or the slave cylinder?
Let me know what you think.... would rather not get into a clutch change-out if I can avoid it.

It sounds to me like your slave cylinder is shot. If its wet around your slave cylinder that that is definitely your problem.

Look at the MC, is there fluid on the firewall, on the outside or inside of truck?

My master cylinder went out and the pedal went to the floor and stayed there. SO i replaced it and problem solved. Now i need to replace the slave, this weekend hopefully.

I orderd both from marlincrawler.com OEM part and pretty cheap IMO.
