I know nothing about transmissions so if anyone who does could help me diagnose and solve my problem, it will be much appreciated. I have an 05 with 50,000miles and when driving hard, 1st to 2nd is slow and hard. When driving normal it goes into gear perfectly but when driving WOT its hard to shift. It comes out of 1st fine, then stops just before its into 2nd gear for a second. Is it the syncro, or something else?

Thanks in advance, DK

Driver error, shift smoothly. No need for a ricer style slam shift when driving hard.

lol its no driver error get the hell outta here with that crap. It grinds at high revs, doesnt like to go in if i sit there for 2 seconds between the shift and put it in slowly its goes in perfectly... its the syncros...

Try changing the fluid.

Not driver error... hah only 50k miles I dont really think much should be wrong with the transmission. correct? I'll try changing the fluid.

Fluid was already said, if that doesnt help, do you have the 60k mile warranty? Nissan gave me new trans flywheel and clutch on my 08 with 21k miles on it. Git while the gittn is good... or

a- its a 5 year or 60k warranty, so times up.
b- nissan fluid has the proper viscosity to help this.. adding torco or royal purple will give you more problems.. i am going back to nissan formula for my new transmission.
And yes OP.. its common. It sucks.. our transmissions are notchy as hell.

I ALWAYS forget this since my Z is 08. Good job remembering!

Yes it is, and it is caused by..............driver error.

try a set of solid motor or trans mounts. cures it on most vehicles. i have 08 that did the same thing on hard launches/high rpm

Sounds like syncros, very common problem with early model Zs with the non-CD009 transmission. Try replacing the fluid with OE fluid, if that doesn't solve the problem the only fix is to replace the transmission with the revised CD009.

Goodluck
