Automatic Transmission problems of the 1997 Chrysler LHS

Not long after buying this used vehicle with about 95,000 miles, I noticed a shudder when I got up to about 40 mph. Now after driving only 20,000 miles it won't upshift after being driven for about 30 minutes and shudders at take off. The dealership won't bill Chrysler for the $2100 tranny repair. I can't afford to be without a vehicle, and a repair bill in that amount or another car payment may put me under. This is very stressing. This is the newest used car I've owned and I thought it'd be reliable. I'll never buy a Chrysler again.

When starting vehicle with foot on the brake, and vehicle in park, vehicle went into reverse, causing a collision/injury. Cause unknown.

Transmission locked up while driving . Dealer has replaced the transmission.
