Stopped at a tint shop yesterday to check out the 3M Crystalline tint for my Z. It's expensive, but I think saving the interior and the heat rejection will make it worth the money so I'll stop today and leave a deposit for the install.

How was the install on the undertray and does it really make the oil change as easy as claimed?
I've been considering one of these since I got my Z.

Ohh I paid 10.25 a quart saw on amazon they had a special so I bought 5. And yea alum tray haha make my life easier

Took it back to the dealership for some work. Last week did all the fluids hoping it would fix my transmission issue.

Still grinding going from any lower gear (2/3) to a higher gear (5/6). Going up the tree has no issues, just skipping 2 gears rapidly causes a harsh grind on the transmission (guessing syncros, but I'm not a professional). Grrrr... at 30300 miles now, expected to be over 36K in ~3 months. Didn't get a Juke, got a rental Sentra as the courtesy cars were all out.

:icon08:

A lot of transmissions have problems with gear skipping... I kind of feel like it's normal, so if I skip a gear, I just put it into the interim gears on the way up, without actually letting out the clutch.. know what I mean?

So for a 2 to 5 shift...

Clutch in
Shifter to 3rd, shifter to 4th shifter to 5th
clutch out


That said, hopefully they can get it working like you want it to!

Edit: Here's a tip, give the transmission's input shaft longer to spin down before trying to put it into the higher gear. That'll take the strain off of the synchros.

I installed the ZSpeed undertray -- it was a piece of cake to install:

Looks good! I've been wanting these but can't get over the gap they leave on one side.

What do you mean?

If you look at the blade, it doesn't run the entire length of the side skirt. Depending on where you place it, the gap can be either on the front end or back end.

I would understand that if the syncros across all the gears were a single set, but having dual syncros on gears 4-6, that's supposed to eliminate any engine speed/transmission speed offset to allow the gear to slide in, and not grind. I'm not in the habit of changing the method of driving to suit one car unless is a specialty car (Formula Enterprise class specifically). I've driven 5 other manual Z's and haven't experienced this (3 were 'before I owned my Z' test drives and didn't drive it in the manner I would normally). The 2 I drove over the weekend were both MT Zs with sports pkg. A 2010 and a 2012, one with 42K and one with 23.5K miles. I could not replicate the problem on either of the two.

Coming onto a freeway, getting up to 55-60 in 2nd, then climbing every gear :3rd, 4th, 5th, to OD would slow me back down to 40-45 and I would end up downshifting again to get back to freeway speeds.

I'm hearing you say, "Oy! Don't accelerate hard in your sportscar (HA HA RACE CAR):roflpuke2:. You'll have to downshift after touching each gear to safely get to overdrive because all that speed you gained was just wasted while you're fiddling around with all the gears your car has in it."

18 vehicles owned, 9 manual cars/trucks. I've seen this only when sychros are crushed (1 car and 1 truck) or the throwout bearings was literally coming apart or an arm broke off(2 cars).

I do trust your judgement, however I cannot imagine grinding from 3rd to 5th is acceptable. If I had video with sound, I'm certain you would agree it's not right.

MMMMmmmmm......caaaaaaake

Thanks. Me too. I'm just all 'stabby' right now with the Z in the shop.:shakes head:

Yeah if it's noticeably different from what the other Z's of similar age and configuration have, then you've almost certainly got something wrong.

Hope they can figure it out, keep on them!

Did you just re-use the factory fasteners?
I think a couple are missing from careless techs changing my oil at the dealer. :/
