What was the cause of the new transmission? Was this something caused by the SC or just something that broke coincidentally?

When the car was acting up we could tell there was extra heat buildup in the engine compartment. A smell of transmission fluid with the rpm cycling wildly way above idle from 1000 to 1400 rpm, until the car was turned off.
To get back to home or the dealership, I had to use Manual up to 5th gear. Any higher, the car would failsafe. So, basically a call was made that the clutch was slipping and a module inside (poor design I think) called the TCM was shot. So, have to replace the whole thing. First step in the troubleshooting process, I guess. So, someone at Nissan made the call and swapped it out.

So, it was viewed that the ECU Program was causing a communication problem with the Transmission. The Z gave the apperance it did not know what gear it was in over 4000 rpm and certaintly not where it was in the shifting range when decelerating to turn a corner. Strange.

i think you just motivated me to remove the kit from my car and return it.

Is it time to give up?

i've haven't received any indication from them that there is a solution because honestly, i don't think they know what is wrong.

weird! i know at least 2 people with the R6 tune and 7AT is running fine now!

i'll check with the dealership tomorrow to see if they've received a new tune.

So, all involved whole heartedly believe it is all programming at fault here and not the machine. Just a long process to eliminate what works and what does not. I truly think that my Z is forwarding through on the last of the unkowns with the SC kit. I have been told the other Z's that have it are doing ok, even after the last modifications I spoke about in my first post. If Osiris you could just hang on another few weeks, the groundwork should be fully laid out and complete. My motivation is the remembering how it drove in the first day and there will be many more like it afterwards.

i'm sure they're gonna take care of you very soon! i got my car back since saturday and it's running very good now. i'm guessing all they need to do is get some datalogging from your dealer and see if it's pulling timing up high and adjust from there.

I am also in a hard decision to just call everyone and pull the plug on the whole thing, but to remove the kit from the car is more difficult to remove than going in. Some parts of the body of the car were modified, cut into, adusted, etc and to restore to original would cause more effort to return like new. Just a sorry spot to be in, right now.

The interesting fact is the Uprev guys in Austin wrote the programs for the Supercharger. So, Stillen is working on a car with these exact same troubles in CA and the Austin guys are working from this end. Collaborative effort here to squash this once and for all. In a weird way, lucky that everyone is communicating on this now and we arent kind of doing this one at a time, reinventing the wheel for each Z that comes in.

you surely have more patience than I. I can't believe you've been waiting since May...and i thought 3 months was a long time to wait.

I know this will stir the pot. but it would be interesting to see if Sam could tune the stillen kit.
