Well I'm trying to chance down an issue with my trans not shifting into reverse when the car is running. It just grinds. I was told that my 2.5 car had the Isuzu trans switched with a Getrag. 1st how can you physically tell what trans is which? Now the issue I think I am facing is a mismatch of parts between the 2 transmissions. What is different between the hydraulic systems. I think my car has a Isuzu slave cylinder on a Getrag. Plus when ya push the clutch in the slave flex's down. Could that be what is causing my issue. I can get pictures and or video if that will help.

The Isuzu has both cables coming in from the top.
The Getrag has the shift cable coming in from the top, but the select cable comes up from the bottom front corner.

Actually, the Isuzu slave has been used as a bandaid to fix clutch release issues on Getrags, since it has a little bit longer travel.
If your slave cylinder or bracket is flexing, something is wrong.

The only difference in the Hyd. system between a Getrag & an Isuzu is that the Getrag slave cylinder has a larger bore diameter. That's why the Isuzu Slave with it's smaller bore has more travel.

As siad by Raydar, some times the Isuzu slave is used with the Getrag as a bandaid fix.

However if your problem is Hyd. related & if your trans is an Isuzu & if your slave is a Getrag slave then you could have the symptoms you describe.

If you are running the Isuzu slave, measure the slave cylinder's stroke. If you are getting less than 1" your problem is hydraulic or bent components.

If it is less that 1" then try to pump the clutch pedal and then see what happens with your slave's stroke. If pumping the pedal increases the stroke, you have air in the system. If not, look for bent components under the dash.

Ive already changed the pedal and bled the system. I'll measure it today and see. This might be a stupid question but where to where do a measure the slaves throw.

Ok well I made a little spacer to put between the slave and the bracket it pushes to give it more throw and it still grinds. I can get it into reverse if I go real fast put it will grind and 1st is very hard to get into 2nd is a little difficult and the rest aren't too bad.

I'm going to change the fluid tomorrow

If tat don't work I'm not sure what to do.

I just bought a NAPA slave cylinder and a quart of dot 3 for $30.00. My slave had died from corrosion and was leaking air and doing like yours was.
With the new slave and flushing the old fluid out, my clutch acts like mechanical linkage! The clutch releases at the top third of travel!
BTW, pumping the clutch pedal does not compress the air and move the clutch further.
