After first starting the car it shifts fine. But after approximately 10 minutes or after the car reaches normal temperature, the car doesn't go into gear! It just completely disengages from the gear and just sits there and revs. It started after replacing the head-gasket. Had to tow it home and it hasn't left the driveway since. After doing research I've found that it could be a speed shaft sensor, transmission solenoid, or a couple other things. Any Information would help a lot!

Hello,

It could be a ground wire that was not connected or tighten during the head gasket replacement. Ground G101 would have been removed check it and all other wire connectors and grounds. I attached ground location and wiring diagrams showing the ground connection below. Repair ground and reset the control module by disconnecting battery cables for 10 minutes.
Let us know if this was helpful and if you need more information.
