Ok, I was reading part of the GM service manual and it mentions a procedure for clutch spin down time. It is as follows:
1. Run the engine at a normal idle with the transaxle in nuetral and the clutch engaged.
2. Disengage the clutch for nine seconds
3. Shift thre tranzaxle into reverse.
4. Refer to "Clutch diagnostic chart" if grinding noise is heard.

So I guess GM designed reverse to grind in the isuzu. But that actually works, if you hold down the clutch for 9 seconds before you put it in reverse, it shouldn't grind.

i should try that, been having problems with it since day one.

also if you put it in first then go to reverse it keeps it from grinding

Yea, i know, I use fourth, it seems to work better

reverse was grinding from day one on mine. Recently took the tranny apart and saw the teeth on the reverse gear are all rounded off. How nice. Oh well, I just put it back in. I mean it still works.

goto 4th before going into reverse. there are no synchro's in rev (THANKS GM!). hitting 4th before reverse doesnt grind. unless you are rolling(dont roll!). i have been doing that since ive had the car and dont have any problems.

Why would it need synchro's? More things to break? More weight? You don't shift the tranny into reverse while you're moving.

The reason the gears look rounded is because they're cast, not machined.


O noes!

I have been having problems with my transmission as far as noise is concerned. I don't believe that it is grinding because it shifts with ease. Could this actually be something to do with the axles because it is only happening when I am in motion and I have taken some nasty bumps in the past few weeks? Thanks for any help guys (and girls)....
