A little background; I’ve had my 83 FJ60 for about 2 months. It has 123,000mi, and what I’m assuming is an original clutch. Yesterday, I took it on a 230mi round trip cruise from Tucson to the phoenix area, and it did absolutely great. This morning I hopped in it to go to the grocery store, and the clutch was slipping a bit in 2nd and 3rd. After driving approx 1 mile, it stopped. I got back home, pulled the inspection cover and took a look. Everything seems good, I was thinking maybe there was oil or something getting on the disc from the rear main seal (It leaks a bit), but it looks fairly dry. So I check the fluid level in the clutch master. It’s low, but not alarmingly low. It’s also leaking down the inside of the firewall.
I cleaned and put the inspection cover back on, took it down to the power washer place where it ran fine and power washed underneath it. Upon leaving, it slipped a bit again then was fine. I’ve ordered a new Aisin master, but do you think this could be the culprit? It otherwise drives totally fine with no slipping when warm. Attached is a pic of the view with the inspection cover off. I know these clutches can go quite a bit longer than 123k, so I’m curious about your opinions.
