Your description of exhaust filter sounds like what the rest of the world calls catalytic converters. They're emissions items and can crumble apart like you've described.
The issues you're having sound like low fluid. Since you recently had the fluid replaced, take it back, they did something wrong.

Ignore what these trolls said about replacing the flux capacitor, the ones on the G35 NEVER need to be replaced.

... so wait, you had this problem BEFORE or AFTER you went to nissan? there are different levels of service departments? 
... lol im so confused
I had the problem before going to Nissan for the transmission service. I still have it after the service. The service wasn’t helpful. Yeah lol we do have it that way here. Really complicated and costs a lot lol.Originally Posted by BIG6
not quite following what you just said ... so wait, you had this problem BEFORE or AFTER you went to nissan? there are different levels of service departments? ... lol im so confused

Checking the fluid is easy, follow the.ptevuous directions about getting it up to temp, park, cycle through gears and leave the engine running. Get out and pop the hood and locate the dipstick which is behind the intake plenum near the firewall. You will need a 10mm socket to take off the retention bolt then you can pull out the dipstick, check/wipe/check/wipe and repeat until you can get a clean reading. Probably will take you 7-8 times of wiping the dipstick before it's clean enough to accurately read. You can add more Nissan Matic J or S using a funnel on the dipstick tube, a little goes a long way, I think the difference between low and high is 1 PINT, not 1 quart.
If it is low though I would just take it back to Nissan and tell them they didn't fill it properly.

I did, cycled gears, cleaned out the dipstick a few times and then checked again. The level of trans fluid is okay (not too high and not too low) and tempered on the running engine.Originally Posted by BIG6

Hello once again lads! So the problem was within the Valve body (TCM unit). Apparently, the switches weren’t passing the current flow and the inner body was jammed. I swapped to a cleaner valve body off an abandoned A/T g35, got it checked with a vacuum test by a specialist and it works fine. (Also before, my triptonic shift wasn’t shifting gears, it does now after I changed the valve body).
Now the problem is that the gear shift timings are messed up. (Slight lag on the 1st gear but does have power, acceleration drops and 2nd would shift on the 3000 rpm, 3rd would quickly engage as it changes to the 2nd, 4th would go up till 4000 rpm).
I somewhere heard that if I reset the ECU, it would match and relearn the acceleration pattern for the shifts? Do you guys approve of this? What do you recommend?? Need to resurrect my baby ASAP.
