Transmission place that doesn't give a shift

Location: Ontario, brampton
Industry: Automotive
Annoyed By: AAMCO

I had ,y minivan serviced by AAMCO in brampton, they rebuilt it and charged me $3909. 6 mths later I'm getting a hard shift from 2-3 gear.
First they said I need a tune up, then they said it's electrical problems. Having got a second opinion from another location then they said 'oh it a mechanical problem "
and they were willing to charge me $1900 to fix the problem before he's even opened up the transmission.
NICE!!!!!!!
