My 2005 envoy started, went into reverse, went into drive and before I got out of the driveway it stopped the gear shift won't move and it won't start again. The lock light came on the dash.

Sounds like the car is just slipping out of gear. Keep your hand on the shifter when you back up next time. See if you can feel the shifter move when the car comes out of gear. If the shifter moves up when it happens keep pressure on the shifter holding it back like you dont want it to move forward. And of course if the shifter moves back when it comes out of gear, put forward pressure on the shifter so it doesnt slip out. This might work for now but but i know i wouldnt want to spen 700 for that ****. Let me know how it goes.

I had this problem a few months ago. I was able to drive the car home by taking a screwdriver and overiding the gear. Read your manual and if your car is equiped with an overide it will give you instructions. A little covered hole is to the left of the shift when in park. It is small circle and you must pry out the cover before using a screwdriver head to push the overide. I had to do this to put the car into reverse and then again to put it into drive. The solution: Nissan Auto Service replaced the crankshaft position sensor. Fortunately the car was still under the Extended Warranty at 68,000+ miles and this solved the problem. At 72,000 I had the rear right motor mount replaced. Too early for this. Now I am needing a new AC Compressor (79,000 miles) and it sounds like I'm on the vurge of problems with my catalyc converter. I have found a link that shows that many other Altima owners like me are having these very same problems at low miles. Check out: http://www.consumeraffairs.com/automotive/nissan_altima.html . Sounds like some recalls need to be done.

Good luck!

Hi all,
I have a 2002 Renault Megane 1.6 Convertible and experienced exactly the same fault. Needed a team effort but we found a very easy quick fix to this problem. If you take the plastic cover off from under the gear shifter, you will notice a release button covered by a rubber cover. Pressing this release button allows the gear shifter to move from its locked/jammed position. (This is not the fix but it helps with the fix).
If you are fortunate enough to have a 2nd person available, have them poke their head under the bonnet to watch the Gearbox cable move....while you are shifting the gear shifter inside the vehicle. Your partner will see that a cable with a plastic locking device (right hand side of the engine cover) has popped off the shifter for the transmission. Move the shifter until you can physically put the plastic locking device back on the shifter mechanism and your all good to go. No need for that new gearbox that you might have been quoted on!! An easy fix that I am surprised no mechanically minded professional/body in the world has volunteered the solution to. I wonder why????

Good luck!

Sounds like a linkage/cable to me. Disconnect the linkage at the transmission and move the shift actuator by hand to see if there is the same things happening. Don't try to do this with the engine running unless someone is holding the brake inside the car.
