I just thought before I start trying to find the problem myself and screw it up.  The autostick was running good a week a go when I parked it.  I was working on backup lights, but I believe I left it in reverse gear.  I went to start car, it would not start.  I took it out of gear and it start fine.

When to put it into gear (reverse) ,it started grinding and did not go into gear.  This is the same for all gears. 

It appears it does not poll the servo on the clutch lever.  I had polled the wire plugs loose on all the sencers when working on backup lights.    Could this because by the contact in shifter?

Check ATF fluid. OK
Check wiring it appear OK

Any help?  I'm still green at the gills on this autostick deal.

Thanks Glenn

So far, you are fine.  The car (if properly wired) should NOT start when in gear.  The nuetral safety switch prevents a start up in gear.

OK.  The first thing you need to know before trying to fix this problem is this............shifting in an AutoStick is an electrical function which is aided by a vacuum system.  Your problem will be either electrical (much more likely since you have been working on the electrical system) or vacuum related. 

QuoteIt appears it does not poll the servo on the clutch lever.

Again, this would probably be electrical.  If it were a vacuum problem you would likely notice something happening.  Some movement in the servo and arm; some hissing from escaping vacuum; something that would tell you there was not enough vacuum to do the job.  That there was no movement says that the electrical signal was never received at the control valve solenoid.

I'm guessing here that you are referring to the ATF temperature sensors in the bell housing area.  That alone should have no effect on shifting.  And it would seem that your nuetral safety switch is wired correctly.  So the problem is not likely to be in this area.

QuoteCould this because by the contact in shifter?

Very possible.

Glenn, I would suggest that you go through the AS electrical wiring from the shift lever points to the control valve solenoid and make sure everything is connected and that the connections are nice and bright and shiny.  But before you do this there are a few spots which have been known to give folks some trouble, so here they are..................

1.  The in-line fuse holder to the control valve solenoid.  It is usually mounted on the fan housing (along with the in-line fuse holder for the back-up lights) just above the coil.  Make sure that the 8 amp fuse inside is functional.

2.  The spade connectors for the control valve solenoid.  The black wire is hot, the brown is a ground.  Both should be securely attached and not grounding out on the body.

3.  The in-line connector found under the rear seat - driver side.  This connector connects the blue wire from the shift lever to the black wire leading back to the nuetral safety switch and on to the control valve solenoid.

4.  The blue wire coming out of the base of the shift lever.  This wire has been known to lose its insulation where it exits the shift lever and ground out.

Mike,

Good call!!!

I have got it working again.  The wire from the coil to the control valve solinoid appears to be the problem child.  I wiggled the wires (black and ground) to clean connection, also on the coil.  I will replace the wire from the coil to control valve because wiring cover is bad.  Plus wire where it meets the spades is starting to fray.

I remembered I removed the defogger wire from the fuse panel so I reconnected it.  But the defogger is a separate circuit,  so I disconnected again.  In the body change over the heated backlite was lost.

Thanks again for the help.
