Why won't anybody answer this question?
 

After reading through several pages of search results from the word "transmission" I've come to a conclusion.

There are literally pages on pages of people with bad AT/MT transmissions ranging in all model years. Now, I have done some research on transmission options, and it seems that only SGP Racing offers an automatic transmission upgrade capable of handling upwards of 850+ RWHP.

Am I to understand that the hundreds of people who have turbo/supercharged their 350Z/G35s and been happy with the reliability of the stock manual/automatic transmissions?

I'm not a big fan of replacing transmissions, I'd rather spend the big bucks to get a transmission that wont crumble than rebuild a stock one 3-4 times, as in some cases is true.

Nobody knows of an aftermarket company that offers beefed up versions of the 6MT/5AT transmissions for our cars?

I haven't seen too many cases of FI guys having tranny problems. Usually just upgrade the clutch. The tranny probs people were having were mainly synchro problems and they seemed random.

:rolleyes: Level 10, SGP, VRT....

Level 10 = Valve Body / No Transmission option for 350Z/G35.

SGP Racing = Automatic Only

VRT = ??? I don't see any options offered.

If your going to make a sarcastic post, at least try to offer something I haven't already said.

+1 ^^^

Sarcasm really sucks on this board.

I'm running with my third tranny. I've had 2 trannys go out on my 6mt sedan because of failing synchros. I wouldn't really call it random either. There are lots of drivers on here that have had their trannys replaced because of the synchros. My third tranny, I have put 40k on it and the last 6k have been with a Stillen SC. Its holding strong so far. I don't know of any 6mt replacements out there though. GL. :)

Z - I just got my tranny back from Speed Force Racing & their work has a 2 year warranty. The tranny work is claimed to handle 1000 rwhp but since I'm selling my G & won't be finishing the "Project from Hell" :mad: I won't be able to provide any real world feedback.:( I had plans to switch to twins plus nitrous so I MIGHT have been able to test the power holding capability but perhaps I can get the new owner to post his results. :cool:
FWIW - the mods cost $4200 & allow 6-8 weeks ( at least!! :rolleyes: ) for completion. :o The work will include a custom stalled & beefed T/C; a modded V/B for firmer WOT shifts & reworked pump pressure system to yield quicker shifts. SFR also beefs up or replaces the clutch packs ( it's proprietary so Tim didn't tell me ) :eek: & that's where the additional power handling capability comes from.
When I was just running N/A mods + nitrous I had Level 10 do their T/C & V/B work & was pleased with it.:) I was probably making 450-475 hp @ the crank w/the nitrous & had no issues for the 2 years I ran like that. :)

My bad. :eek: Automatics only... Did you call and ask?
