2001 Pontiac Aztek transmission problems

Tl*the contact owns a 2001 pontiac aztec. The vehicle was locked in the park position. The contact read the owner's manual and attempted to release the vehicle through the cupholder as instructed. She could not do so on the driver's side and went to the passenger side instead. She was able to release the lock and was on her way back to the driver's side when the vehicle knocked her down. According to witnesses, the vehicle made an l and struck another vehicle. The vehicle was towed and has not yet been diagnosed.

When I purchased my astek in july 2001, it was brand new since I have had it I have had brake problems , a wheel bearing has went out, my alignment was set wrong, I needed to get brand new tires, and my transmission is now out and its not under warranty due to high mileage. I will be investigating. And now it is sitting until I can afford $2000.00 for a transmission or I can get this resolved.
