Sheridan Motor

My jeep has not been shifting right since February of this year (2014). It grinds and does not want to go into 2nd or reverse most of the time. It also clunks coming out of 2nd into first. We took it to the dealership and they ordered the wrong part (on backorder for 6 months), finally ordered the correct parts - stating our syncro's were going out, and replaced the syncros in Sept. The jeep is still having the same issues, but now the dealership is not recognizing it as an 'issue'. They say it drives and shifts fine, yet other technicians (outside of the dealership) clearly state the transmission is not working correctly. Sheridan motors has told us (John Koltiska - owner) that they will not be able to help us further and to take it to another dealer if we want resolution. We just want our jeep to shift properly...but instead we have just been close to tears of frustration. Do not purchase your vehicle from them or work with this business unless you want a constant headache.
