My prado 2003 with 170000klm v6 4lt. 4speed auto is jamming in gear when in park. This happens usually when parked on an angle either forward or backwards and has started 6 months ago. We have found that the only way to release the stick is to hold the shift lock button down and pull the stick back. As this is a short term solutition I need to fix the problem. Any suggestions wher to look for the problem. In saying this the stick and box assy housing (plastic)as been replaced because of a failure in the stick assy so only after this did the jamming start. Hope you can help.
