Transmission problem
1989 Toyota Pickup 4 cyl Four Wheel Drive

I recently started having a problem shifting my manual transmission. It became more and more difficult as time went on, and I remember hearing a wierd click or snap noise just as it first happened. I tried replacing the clutch master cylinder, and after installing and bleeding the system, now it won't shift at all. Could it be the clutch slave cylinder? Or have I mad a mistake somewhere in the master cylinder replacement process? Anything el;se I may have overlooked? The transmission was replaced about 4 years ago with a factory new, not rebuilt unit, and has about 30,000 miles on it.

Thanks

HI there,

Check that there is no fluid under the rubber boot of the slave cyl, if so replace it, there is no adjustment on these clutches, do you have good pedal pressure and is there any free play in the pedal before it takes up pressure, (there should be about 5mm free play) where dose the drive take up when you release the clutch?

I seem to have a lot of play in the pedal before pressure is up. The fluid level never dropped, so I am assuming there is no leak.( I could be wrong.) Ther is some fluid around the slave cylinder, but there is some oil all over the transmission and engine. I'll clean it up and recheck. Maybe I didn't bleed it enough, either.

Thanks again, Rick

Just peel back the boot and if there is fluid there replace the slave and re bleed.

Ok, I have replaced the slave and master cylinders for the clutch. The system has been bled. It shifted ok for a while, still a little hard to get into first and second gear. After a while it became increasingly difficult to shift again. Then the clutch seemed to be slipping, but then grabbed abruptly. Could it be that the clutch is coming apart inside, and the new parts have help to accelerate the damage? Or could it be the clutch fork broken? The clutch has about 25 to 28000 miles on it. Anything else I could be overlooking? Thanks for the help.

Hi there,

If you have good pedal pressure and t clutch feels as if it is slipping I would be replacing the clutch, but first I would be making sure that the transmission oil is ok, the hydraulic system is very basic so if that is new and you have good pressure and throw, with poor clutch operation I would be replacing the clutch.

I understand the slippage means that the clutch is bad, but would that account for the difficulty in shifting that is still a problem? I've had slipping clutches before, but never had the shifting problem. Please advise.

Thanx, Rick

If you have a problem with the pressure plat and it is not fully releasing the clutch plate this can cause the hard shift, combined with the worn clutch plate this can cause the slipping, have you tried to change the transmission oil yet? Just to prove a point that the syncro are not hanging up due to poor oil quality? If you do this and you still have this problem I would be replacing the clutch Assembly, make sure that you machine the fly wheel as if you don't you can have shudder problems, also replace the thrust bearing and spigot or pilot bearing as well.
