I have 04 5AT maxima with VB problem. The car fail the Vehicle Inspection test. The fault code is PO780 shift malfunctuion and PO797 Pressure control solenoid "C" stuck on.The problem -jerking and banging ,in a stop and go traffic started last year. I took it to local tranny shop and he is asking $3500.00 to replace the VB and chek on the transmission . I think he is asking a lot . Does any one know any shop in the DFW area who can replace the VB ?..I have read a lot of horror stories with their VB's not installed properly. If any one knows a good shop who can do the job please please help a lady . I have to do it asap..Thanks
