Need help!! Having issues with 2003 Discovery II no modifications. After driving and vehicle placed into park, it will not go back into reverse or drive. Have to wait approximately 15-20 minutes and then it will work again. Shifts fine and runs fine when works, just have to wait before retrying. Recently changed xyz switch, transmission fluid and filter but still having same issue. Ideas?

 

Did you replace the XYZ with a new or used unit? My buddy had the same problem and the used XYZ that was supposed to be good was not.

 

yes xyz was new I finally was able to get a person at auto-parts store to give me the codes that finally came up I will post them later today thanks for the help.

 

will it not go into reverse or dive because the shifter solenoid will not let the shifter lever move? or is the lever moving but the transmission is not responding.

 

The lever moves but the transmission is not responding.codes are as follows p0160 p1884 p0734 p0138 p0139 p1171 p1174 where do I need to start?

 

Looking at your 'P' codes you have a bunch of oxygen sensor faults, I suspect you have the wrong sensors fitted or communication is poor. For certain Amigo you have mixture adaption issues.

The transmission fault is p0738 Torque converter module (TCM) engine speed output circuit low. The p0734 is 4th gear incorrect speed ratio.
Time to get someone into the transmission to diagnose the internals.

Can sound expensive!
