trouble shifting into 3rd 09 z
 

hey guys so i recently got my trans and diff fluid changed . i went with oem fluid from nissan. (no i didnt go redline for several reasons) anyways about 300 miles after the change..all shifts were smooth. then all the sudden today i was at a stop light, i go from 1st to 2nd then from 2nd to 3rd .. i could not get it into 3rd. it was just stuck. this happened 3 times before i got home. afterwards like 3 hours later i went back out to go get dinner...first couple of shifts were fine then it happened AGAIN. maybe i wasnt pushing the clutch all the way in. so from then on i made sure i pushed the clutch ALL THE WAY IN and then shifted to 3rd...still got stuck. im in panic mode because i just got the car it only has 21k miles on it and is not under warranty. im only 18 i dont have the money for a new trans nor the labor to put it in . worst part is sometimes i would try so hard to get it into 3rd i get it into first by accident and the RPMS go BOOMING. i need help with this problem guys please help me

who changed the fluids for you ? Take it back

i would put your car on a ramp, remove the top fill plug on the tranny (10mm hex) and stick your finger inside to see if you can feel oil in there.

if not, you're low on oil.

also check your clutch fluid level.. and the color. if it's low or like orange color, time to
change it with some fresh brake fluid.

you're 18, you got plenty of time to learn the basics of car maintenance. :D

btw, download the service manual available free on this site.
