95 R33 GTR - odd shifting problems

[kengeroo]

having some unusual behaviour in vehicle.

About 3 out of 10 times up-shifting into 4th gear results in some grinding, same thing with down-shifting into second.

Absolutley no problems with the other gears up or down...

Clutch is bled...

..any ideas???

thx..

bad synchros? check gear oil?

[kengeroo]

if it was a worst case scenario...syncros..
a tranny rebuild or replacement from ebay/etc..
what to do ??

[derk]

try flushing it with some new fluid first

[kengeroo]

....fluid in tranny was low !!!... ordered some RED line GL-4 ,, hopefully this will clear it up...
stick with Red Line ?? or goto something else??

[Zacho]

Redline MT90. That stuff is magical.

[GTRADDICT]

I feel a tranny fluid debate soon MT90 vs Shockproof. I would flush the tranny first. If that doesn't work you'll have to start looking for an other r33 rb26 (clutch is different then r32 Pull vs Push). I honestly don't know how it would cost to rebuild the tranny...
Good luck!

P.S. Write whatever you do with results! Always good to know

eeks

...so hypothetically speaking let's say that yes I did a tranny fluid change...

...and on the magnetic drain plug there was the expected bits of metal...
but also there were 2 strange looking clip like thingies...

I don't think they are part of any gearing or anything....

....any ideas what they are ???

...should I be afraid ? very afraid ???

..and no the nickel didn't come of the tranny...

[derk]

usually... transmissions do not come with spare parts inside.. so id be very afraid.

probably has something to do with the intermittent grind you're having

thx... okay next question,,, best place to get the thing rebuilt,,, went to ztunes they mentioned the tranny shop next to them is able to rebuild it.. Anyone had any expereince with them or know a good shop to do this ???

These clips braking and falling off seems common. What are they anyways? I quickly looked at the thread and they didn't say.

[mitch32]

I don't know what it is but don't be worried, it won't mess up the engine. Also you can get gtr trannies with the transfer case for 250-400$ at a JDM shop. MT-90 and Redline Heavy Shock Proof cured my tranny grind.

Did some more fine detective work and it seems other vehicles have the same problem
