Well, here's a lesson for you kids:
Make sure you don't mess up the parking pawl when you reinstall the extension housing.
Amber noticed today that 'Park' doesn't keep the car from moving. Oops. I'm glad she uses the parking brake.
I know exactly what happened. When I was wrestling with the extension housing, trying to get it back on, I hit the spring for the pawl. I thought I put it back in the right place, but apparently I didn't.
Whoops
I'll have to take it all back apart again when I get back from Minneapolis.
I'm going to go look at the manual and make sure it's not dangerous to drive, in the meantime. I don't think without that spring it can accidentally engage park while the car's in motion, at least.
But I am more than a little worried that the noises she heard were the reduction gears chewing up the spring.
