clutch slipping

Hi group...I have a '93 Toyota 4x4 pu that is starting to slip occasionally
in 4th gear. Is there anything I should try before just having the clutch
replaced...like changing gear oil or anything?
Thanks,
Brian

It's a manual trans, right?

Over 90k miles or tow a trailer? If so its the clutch disc --- assuming the
clutch master cylinder had flhid in it. If its empty then slave or master
cylinder could be gone --- but they affect engagement mainly.

An "Old Timers" way to check the clutch is to gently pull up to, and
nudge, a big tree. Then put your tranny in 3rd gear, rev up the engine a
bit and let out the clutch pedal. It should kill the engine muy pronto.
If it takes a while then you have a worn clutch disc or a defunct
pressure plate, or both. Gears do not slip, clutches do!

No. If the clutch is slipping on a 12-year old truck, odds are good that you
need a new clutch.

no.

your clutch is done. have it changed or change it and replace:

- pilot bearing
- throwout bearing
- crank seal trans input seal

if the oil pan leaks it can also be tackled now

The mileage doesn't matter, I've seen OEM clutches last over 150,000
miles and some fail after 30,000. It's a matter of how their driven.
The original post said nothing about engagement, just slippage when
already in gear.
