OK. . .so this is more annoying than anything else, but my shifter button doesn't stay in the shfter handle anymore. It's been popping out from time to time for about the last 100k miles, but lately it falls out just driving down the road. It looks like there is a small tab that broke off that used to hold it in. Any ideas on how to get it to stay in or where to get a new one?

junk yards very cheap

you will see "u" shape pin on the handle take it out, pull the handle up, disconnect connector for the ets, and shifter button and see where the problem is. Or simply just replace with the one from junk yard
