If the getrag transmission has been apart, it is possible to have one of the shift rails slide out of position during assembly and lock the transmission into 2 gears at the same time...
I normally like learning something new every day, but that day I wasn't so pleased.
On mine, the reverse rail was pushed too deep into the transmission, so I removed the backup light switch and drilled a small hole at an angle on the side to access the end of the shaft and was able to pop it forward w/o taking the transmission apart again.
