1993
Toyota
Tercel DX,4D
engine size?
5 speed manual
115000 miles
average driving city, short distances
I am asking for help because I do not know much about car repairs.
I have replaced the clutch last year August 2011 because of a problem that has now returned nine months later. Now, the repair person says to meon the phone today, it is possibly my transmission. I fear that he may not be a good diagnostician, and I end up repairing one expensive idem after the other.
PLEASE, can anyone help? What do you think is? Is it my clutch or transmission? Or possibly something else?
Last year before the clutch repair, I looked up the same symptoms online and to me it seemed like a clutch problem from what others were talking about.
To me it seemed like the pressure plate was not releasing the clutch disc, at least that is what I gathered from people talking about similar symptoms.
The mechanic then repaired the clutch and he apparently agreed. ( This was a regular car mechanic not some special clutch repair place.
But now that the clutched is fixed, supposedly( I have new clutch), the problem occurs again nine month after repair.
Now, as I said, the same mechanic thinks its the transmission at least from my description.
.
The problem occurs randomly, but frequently and more often when I start the car up, or on intersections when I have to stop, or after I maneuvered the car to turn around.
I do not understand cars much but enough. I do know, however, after driving stick shift for a long time, my car should not be driving forward when the clutch is down all the way. and I have not yet given gas. And my car does that, at least slowly.
I am very confused by what the car is doing
Suddenly, when I press my clutch and want to shift into first gear I cannot do so it does not move in the gear box.
I then have to either shift into rear gear, and after that into first gear. Or on occasion sitting on an intersection and not being able to turn to first gear, I have turned off the car, pumped the clutch, and then turned the car back on. After that I was able to shift into first gear.
Aside from having difficulty shifting into first gear, I also have difficulty at time shifting into rear gear ( difficulty means difficulty moving in gear box, just cannot get the gear in)
The worst of the problems is the car rolling forward when clutch is down.!!!!
I start the car, I press the clutch all the way down, I shift into first gear. While in first gear and I have not yet released the clutch, or given any gas, and THEN my car is rolling forward as though it already has gotten gas or as though I had released the clutch pedal.
Is my clutch not properly fixed or what is it in your opinion?

You have a problem with the hydraulic clutch system, possible the clutch master or slave. It will have to be inspected to determine where the hydraulic leak.

If the hydraulic linkage reservoir is quite low that could cause it to be intermittent but it shouldn't consume fluid. As HT just said check or have checked for a leak but it can fail without leaking - master cylinder for it, flex hose or line, or the slave cylinder.
IMO this has nothing to do with the clutch job and if it behaved in front of a mechanic could be missed without your description. This doesn't seem like trans itself and not sure why you were told that but forcing shifting when not disengaged will cause problems if ignored. If found very low fill it with proper fluid only which is usually DOT 3 brake fluid and may say so on the cap. If not sure about the item and where get it filled at least till you can get it fixed if low,

Thank you so much for the advice regarding the hydraulic clutch system.
You have helped me greatly!!!
I thought when a mechanic fixes the clutch, he does fix all parts, meaning the hydraulic parts as well.
Thanks to you, I know now that the master cylinders of the clutch are called hydraulic parts.
The mechanic must not have fixed these hydraulic parts, otherwise I would not have the problem nine months later again.
I am surprised though that my problem was gone for some time.
I have no idea, why the mechanic said the transmission might be the cause.
.
Since the problem comes and goes, the hydraulic system makes sense.
Today, I got stuck again in first gear at an intersection, I could not move forward, or disengage the clutch, and I could not get out of gear either . After turning off the car all was ok again.
I think I am going to have someone else look at the car.

We can't tell you exactly what is wrong without seeing your car. We only give you things to check. the car has to be checked now.

I like to update on my problem, for one because I have one other question, but I also hope my description of my scenario and your advice may help someone else.
First of all I found my receipt from my clutch repair in August 2011 and learned, I had everything new with my clutch, including master-cylinder and slave -cylinder.
The parts must have been after market parts because I paid something like 53 $ for the master-cylinder.
I went to a clutch and transmission place for an opinion now.
The person drove the car, and saw that the car moved forward when the clutch was still totally engaged.
He said, he thinks its my master-cylinder.
He said either the part was faulty to begin with, or the clutch was assembled somewhat incorrect and the seals of the cylinder got pushed in. He thought that it was wrong not to use Toyota parts.
He also said that there was something wrong in the clutch assembly under the hood, and that is why the clutch engaged only all the way on the floor ,and could not be adjusted within the car where the clutch pedal is.
I then went to another general auto place.
Their opinion was it is either the master-cyclinder, or some other screw, or bold in the mechanical assembly. But they did not drive the car. The latter would of course be a lot cheaper. The Toyota master cylinder is quite expensive
He also said I would only use Toyota parts in the hydraulic system nothing else.
Is it really so wrong to use generic parts, or after market parts for the hydraulic system?

I have 2 issues with what they are saying. Aftermarket masters work just fine. I use them all the time. The other thing is that hydraulic clutches are not adjustable at all so he shouldn't be looking for an adjustment if he knows what he's doing.
Did anyone determine if it had lost any fluid?

Re Aftermarket Parts: Some are fine or better and some are a disaster. China made stuff gets the prize IMO even though if requested I totally believe great stuff could be made but the demand is for insane low prices and they can do that too.............
