Low output speed sensor rpm, above 15 mph. The sensor is probably bad, it screws into the left side of the transmission extension housing. It is cheap and easy to change.

I have a 1998 dodge caravan 3.3L fault codes p0500 p0700 p0720 p0715, how do I repair and replace sensors to pass smog test


Follow the links for each fault code.
http://www.obd-codes.com/p0500
P0700 Transmission Control System Malfunction
P0720 Output Speed Sensor Circuit Malfunction
P0715 sets when there is an error in the transmission's input speed sensor signal. On the front of the trans there is an input and output speed sensor that the trans controller looks at for shifting control.

While the code could have set because of a wiring or connection problem, it's almost surely the sensor. Input speed sensor failures are not uncommon.

The input speed sensor is mounted right on the front of the trans directly under where the cooler lines attach. It threads directly in and has a 1" hex for a socket for removal. If the wiring and connection look visibly ok then I would recommend replacing the sensor

My 1994 GMC Suburban wont shift out of first.....but will shift to second manually but wont go any higher........?


Sounds like a vehicle speed sensor, it governs shifting based on engine RPM vs Transmission RPM among other things. Located usually on the rear tailshaft or rear transfer case on the majority of 4L60E automatics.

2001 Dodge Grand Caravan 3.3 Motor 4 Speed Transaxle 41TE The codes that come up are P0700 Trans Control Sys Malfunction P0720 Output Speed Sensor Circuit Malfunction P0732 Gear 2 Ratio Incorrect When...


Replace the transaxle or see if it can be rebuilt. Those transaxles have incorporated electronic solenoids that can fail causing the codes to appear as you described. One thing you might check prior to getting it rebuilt or replaced is have the computer checked and check all of your wiring connections. Anytime you have a wiring connector on the exterior of the vehicle you can get corrosion issues it may be simply cleaning the connectors, placing dielectric grease on them and reattaching. Before cleaning any connectors always disconnect the negative battery terminal.

1995 sunfire wont shift gear


There were two different automatic transmissions in the Sunfire that year,the 3 speed trans designated the 3T40,and the 4 speed trans designated the 4T40.If your car has the 4 speed trans,there will be a circle around the "D" on your gear selector indicator.The 3 speed trans will not have a circle around the "D".The 3 speed trans works off of a cable called the TV or Throttle Valve cable.This cable should be checked where it engages the throttle body around the area where the throttle cable attaches to the throttle body,on the engine.If the cable becomes disconnected for whatever reason,the trans will not shift out of 1st gear in most cases.If the car has the 4 speed trans,this model trans is totally electronic,and the vehicle should have the codes pulled out.For every trouble code,there is a diagnostic route to follow to repair the malfunction.

Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.
