So hey guys I just started noticing a problem with my 5th gear if my rpm is over 3000 and I try to shift into or down shift into 5th big grinding sounds but if I wait till my revs hit around 1000-1500 it's smooth as butter anyone know what's going on??

 

Syncro is going bad.

 

How much am I looking at to replace?

 

Varies from shop-to-shop. Plan on $1000-$3000.

 

I can tell you what is going on. You need a new transmission.

 

You are better looking at a used tranny than fixing the synchro.

 

What about your warranty? Nissan has a 60k mile/5yr on powertrain. I'm not sure how it works but you might still have a little time depending on how old your 07 is? Doesn't hurt to try that first.

From the warranty book : "THE WARRANTY BEGINS
The warranty period begins on the date the vehicle is delivered
to the first retail buyer or put into use, whichever is earlier"

 

Truth. If you can do the swap yourself it will be closer to $700, if you have to pay a dealership it will be closer to $2000

 

First see of you have warranty if not then try changing your Trans fluid to something like Redline MT85 with a but of Lightweight shockproof. If that doesn't work find a used Trans get a friend to help you install. Btw do you know how to double clutch? (lol no not talking fast and the furious) its a good way to further verify that its the synchro

 

how many miles on the car? My 5th gear went bad, and instead of buying a used transmission (b/c used units can still have the 5th gear problem), I took the hit and bought a new one.

 

Had the same problem on my base 07 as well. It was under warranty when I took it to my dealer. Free repair bro

 

I just hit 70,000 and explain the double clutch please

 

u are fawked, sell car.

jk.

u have all the possible replies u need on the thread.. search, read, and take to shop.

thats about it man.

 

lets use going from forth to fifth to explain:
you would be in forth, clutch in, put it in neutral, clutch out, clutch in, put it in fifth, clutch out.

Our transmissions are synchronized so there is no need to double clutch on a daily bases, but if you still have a grind when you double clutch in confirms you synchro is going

 

yep ^^ otherwise ya just got air in the juice, probably from a bad or dirty master cylinder.

 

Thank you I'm going for a drive right now to see what happens I'll get back to you Guys thank you for the good help

 

Should I wait for rpms to drop or do it fast?

 

Bump

 

How much am I looking at if I have a shop change my tranny to a new one
