Well, my first indications of tranny damage... 3rd gear grinds hard when shifted from above 4000 rpm(that means 2nd to 3rd shift)... Also, the shifter started to get heavy to shift any gear..... This happens when the car is driven for a long time..

Q.. Is there any chance my tranny oil, which is synthethic, has to do with any of this. I ask this cuz it started doing it when i changed the tranny oil

 

Which tranny oil? I have heard that synchros don't like synthetic tranny fluid unless it's specifically designed for sychros (like BG Synchroshift or GM's Sychromesh)

 

your car should still be under warrenty, take it in and find out whats up, its prob. what otter said, some tranny's dont like synthetic.

 

Not if he takes it in and they drain an unapproved fluid out of it.


If you put in something like Mobil1 synthetic gear lube, it will grind. Try changing it to BG Synchroshift or GM or Pennzoil Synchromesh. Drive around a bit on that stuff to flush out the traces of the synthetic in there, and the shifting should get better.

Listen to this man, he knows what hes talking about.

How did you know it is THAT oil the one I changed to? Already had a problem with it?

Thanks for reminding me about the oil

 

good advice i didnt think about the dealer trying to pin it on him, i should know better

 

Had a problem with it in a previous car, have heard of others having problems with it in their Lancers.

 

I have issues as well (Using Mobil1,) and as soon as the @ss holes I work for quit forcing us to work weekends as well as our regular 50+hrs mon to fri I will change it out. At least I will have the money to buy the good stuff.

 

^Mobil 1 synthetic tranny fluid is not all that great of a product. I ran into the same problem in the past and switched to Royal Purple's Sychromax and never turned back. Try using RP's Sychromax or GM's Sychromesh, I think you will be pleased.

 

tuyo no es auto?

 

No, PR Mivec is not an auto... I stay true to the original fiebru recipe

Just when the car's clutch is in its last legs this happens....that and my tires cant take the power anymore

BTW Got me some Royal Purple today, lets see if it calms my worries

 

se me fue el avion lol
my bad

 

bought some royal purple, waiting for it to ship. I will let everyone know that I agree with what everyone says about Royal Purple all the time when I change it

 

^^Yo dan, what part of charlotte do you live in?

 

Does anyone try / use Redline MT90 ? 300ZX are notorious for tranny 4rth gear grinds and synchro issues. These stuff and Royal Purple seems to cure most issues.
