Troubleshooting 2000 maxima rough engine and transmission performance

SOURCE: my 2000 maxima transmission is leaking slip[ing

frist thing to do is vcheck the trans fluid level. you do this wh4en the car is running. If it is very low it can make the transsmision slip. That would eb the frist thing. next you should also get the code pulled for your car. I might guess and say it is a p0720 code. let me know if I am right and motor mounts are no bad. you will have to disconnect the wires that go to them they have brown connectors and a bunch of clips you will have to disconnect. after that you can take out the long bolt that goes throught the middle of the mount and then take the cross memeber down . you will need a jack to be able to do this job. once you get the crossmemeber down it will have the mounts still on them you chnage them and then put it back in reverse order.
