Vehicle is a 2001 Dodge Durango 4.7L 4x4.
When you first erase the codes they come right back with, P0736 Reverse incorrect gear ratio, P0734 Incorrect 4th Gear Ratio and P0720 Output Speed Sensor Circuit Malfunction. But after you start driving it adds P1794 Speed Sensor Ground Error, P0715 Input/Turbine Speed Sensor Circuit Malfunction and P0733 Incorrect 3rd Gear Ratio. As far as noticing anything while driving, as soon as you start off it shifts into second too quick and feels like there is lack of power at lower speeds due to tranny not downshifting. RPMs stay around 2k-3k at all times. I pulled the VSS from the tranny and ohm'ed it out, it came out to about 600, i read its supposed to be between 300-1200. Personally I think the P1794 Speed Sensor Ground Error is the main problem with the P0720 Output Speed Sensor Circuit Malfunction and that is triggering the other codes. But I would like your suggestions on what to check next, how to do it and what you think about this issue. All help is greatly appreaciated. Thank you in advance.
