I buy a new car and drive it on public roads. I drive very hard, at every chance I floor it to the speed limit. So the drive train breaks. Does this mean that that its my fault, well yes. But if its under the warranty period shouldnt the dealer fix it?

 

That's a good question, and to be honest, I think it depends on the stipulations of the warranty that you agreed to when you bought the car. In general, however, I believe in taking responsibility for my own actions.

I don't abuse my 2k Maxima because I want it to last, and the abuse I heap on my 95 I am willing to take responsibility for. It's a moot point, though, since the warranty for my 95 is long over.

 

 

I know I am a good five speed driver and I jammed the car from 2nd to first by mistake, same thing happen a funny noise but it went away. So dont worry about the shifting ****. Keep that extended warranty. It covered my complete drivers side axle, that was over $300, and all six of my coilpacks. They also covere towing charges up to $100.00 and I had my car towed twice. You never know what will break in your car. Some Nissan dealers are cool some are just plain D!cks so fck em. As long as you removed the Coca cola can and everything dont worry they should replace your tranny. What are they they goint to say to you?

 

 

 

14.7 @ 90 mph (stock clutch and bad shifting = slow mph)

 

You win.

 

 

This one is aimed at the tech savvy people.

I arrived at the dealer today just as the tech was taking the gearbox apart. I studied everythign as much as I could and here is a list of the things I noticed about the VQ35DE / RS6F51H.

1.) The bellhousing may indeed be different than the RS5F50(A/H), bolt placement wise. I should know more within a few weeks.

2.) The flywheel on the VQ35 is a two piece unit. The mating surface is an addon part to the actual flywheel. It is held on by 6 rivits or flat top bolts than may be removed from the back of the flywheel. It looks like they did a good job removing alot of excess metal so there wont be much weight to be shaved.

3.) The flywheel is held to the crankshaft by 8 Torx style bolts. The bolt size and pattern (spacing) is not the same as the one on the VQ30DE (A32). You aren't likely to swap flywheels between these engines at all.

4.) The timing ring on the flywheel is also different than the one on the VQ30. This ring does not have 360 teeth. It appears to have groups of ridges that are spaced out for reference points. This explains the missing reference sensor on the crank pulley.

5.) The clutch disc has no springs. I found this to be odd but it seems to work fine. It also appears to have alot more meat on it than the 50A clutch. I can't tell if the overall diameter is larger but if it isn't then it makes more use of the inner diameter for material.

6.) The pressure plate appeared to have a thicker than normal diaphram which gives it plenty of force. I am curious to knwo what it's test pressure is. I bet it's as good as a stage one or two street clutch for a VQ30.

7.) Reverse is no longer a straight cut spur gear. It is now two constant mesh angle cut gears with a baulk ring syncronizer like the rest of the gears. I had my suspisions of this because reverse makes no noise and you can put it in reverse while still moving forward at 2 or 3 mph without hearing a grind.

8.) First and Second gears are pretty thick and look liek they can withstand massive amounts of torque. This is generally how Nissan builds their trannies.

9.) Third gear is much thinner than first or second but a bit thicker than the rest. It looks to be of a similar thickness as most other Nissan units. This gear will be prone to failure from too much clutch power.

10.) Fourth, Fifth and Sixth look somewhat wimpy for a car of this power and size. These gears may still be stronger than the 50A cousins but I wouldn't put too much faith in them. A 4 puck racing clutch will eventually break one of these.

11.) The differential does not appear to have different size bearing races between the helical or the standard unit. I havent seen a standard unit but I know this bearing race isn't anything like the oens they used on the Viscous couplings. I am about 90% certain that an OEM helical diff can be dropped into any RS6F51A without machine work. I will know for sure ina few weeks when I get to see the innards of the 51A.

12.) I could see the helical gears within the diff. There were 4 sets that I could see. Nothign techincal to report other than I though it looked cool.

 

so what did they say about your tranny/car?

 

So are you saying that it may not be possible to bolt the a 3.0L 5 speed up to the new 3.5L block?

Does it look like the 3.0L flywheel can be bolted to the 3.5L block?

Pics of these areas would help allot

Thanks!

 

I looked it over quite a bit but I still don't know for sure. The parts I was looking at were vastly different. There is no way I could know for sure about the bolt spacing without taking measurements. As of right now it looks like any type of mod like that is going to be a PITA. Even the tech commented on how weird the flywheel assembly looked.
I didn't take pictures because I messed up my camera trying to mod it to accept a Type II microdrive. I will borrow a camrea and take pictures if I get the chance.



nismo2020: Yes it was discussed but at this point I want to keep the details to myself. I will just say that it's not likely that I will have any out of pocket expenses. I will mention some details after the job is complete.

 

Can you tell us at least what broke? What bearing was whining? What was the extent of the damage? Was it visable?

 

Hope everything works out for you!

Take some pics of your tranny if you dont mind? we would like to see what your tranny looks like. You have to go to the dealer becuase those guys usually work very fast.

 

I never said anything broke. The bearing whine and 3rd gear synchronizer were the only problems. To avoid potential conflicts im not giving out details untill after the job is complete.

 

Damn, sorry to hear that. Was looking forward to see you possibly break some high 12's on the 25th.

 

Thanks for the info, I would have thought you created more of a "conflict" by telling about your using nitrous and missing a shift than by telling us what was wrong in the transmission. Whatever.

 

well thats exactly what I thought. I just don't want to add to it right now. Besides, everyone knew I had nitrous anywyas.

 

I understand. Ck your PM for my reason for asking!
