08 Edge clunks very loud going into reverse

Any body experience this? When you shift into reverse there is a loud clunk(bang) going into reverse? Or another transmission issue. Sometimes starting out from a stop it will not shift up into a higher gear. To fix the problem just turn the key off then back on, then it shifts normal. Stan

Both, if the turbine speed or output sensor fails, the computer does not know how fast things are spinning on either end, it also fixes the clunk.

 

Get them replaced before they totally fail and leave you beside the road out in the middle of nowhere.

 

$700-900 if done by a mechanic.

If you have AWD, then yes the driveshaft/RDU can come into play for the clunk into reverse. Although you are more likely to need a new Transmission Range Sensor. I would check the resistance on the sensor connection to see if this might be the case. If it is, the work is almost the same as to replace a TSS/OSS sensor, so you can get the whole shebang done in one shot. Advisable to check the valve body and solenoid body assembly while you have them out as well.

 

If it clunks going into other gears also, definitely check the trans mount/dogbone, visible underneath the vehicle from behind the front wheels. These mounts do tend to go south as the miles pile on. How to Check
