61K is REALLY early for it to go.
I have heard of them going from a lot of low-speed pedal use going over obstacles like rocks and such.
Even from using it in other areas like sand and slow trails with a lot of pedal riding time "using the clutch"
Is this the case?
Pushing the pedal all the way down - shifting and quickly / fully releasing (normal shifting) should not lead to failure.
But carrying a lot of weight and working the clutch A LOT will cause faster wear and get it hot.
Heat causes glazing and it will have symptoms of a slip just like wear will.
Grease and oil can also cause it to slip. Have you looked for an oil leak?
I have seen these trucks go 300K on a normally used and operated OEM clutch.
Even 100K is super early,..................... unless it was pedal ridden and was glazed or worn from a lot of pedal slow-release also. known as riding of the clutch
But my opinion would be to get someone that has done Tacoma clutches before, most likely a dealer.
Two reasons,... EXPERIANCE and WARRANTY.
FYI - the clutch pressure plate could also be part of the problem; this is usually caused by holding the clutch down a lot.
Like sitting at red lights or waiting in line at a drive thru.
-
If relacing one part,... replace ALL
clutch - pressure plates - throw out bearing and fork - resurface or replace the flywheel also.
61K ???? This is too early IMO,... something is wrong, or it had a hard life.
