I just got a 92 300zx twin turbo auto, I recently blew the upper radiator hose and when I placed it the car wouldn't shift when I hit the brake..... I push the little switch in front of the shifter to manually move the the shifter, but it won't engage in reverse or neutral. Any thoughts what could be causing this??? Thanks

Sounds like somethings out of adjustment, or bent. Here's a link to the service manual. XenonZ32.com

Sounds like the shift linkage is broke, bent or just came off.
