Just bought 2002 Intrepid 5.7L 154,000 miles Guy we bought it from said it had a radiator reservoir leak and also needed trans pressure switch (per his Dodge dealer). Drove it home and would thump (whole car would move when stopped at light). Replaced reservoir and solved overheating problem. But when replacing pressure switch, test driving when done it is stuck in 1st gear. It is reading codes p0700 and p0936. Replaced celenoid. Still stuck in 1st. And reading same code errors. Anyone please help with suggestions!!!
