Good Question. But I don't think anyone will know until it's tested. I would guess +20% shouldn't be a problem, unless you race frequently. That would be about 350 HP. For all we know, it could handle 400HP. But who knows.
Anyone have an experience with modern Automatics and higher HP?

A good question to ask is how similar the tranny is to the 5-sp tranny found in the Q45. I was under the impression that they were the same in the G35, Q45, and G35C just using different shifting algorithms... don't know about the Z though...seems very similar looks wise.. lol

Almost every Levelten "built" auto tranny on a Supra I have heard about has taken a crap after a very short period of time. I knew one guy personally who had reoccuring problems with his, but then he's pushing 600hp at the wheels. I haven't had any problems myself, so don't have much room to talk, but I would nevew go through them myself given all the bad stories I have heard.

McDan. That is not good news since I was going to send my valve body and converter to Level Ten this spring. Have there been tons of problems or just a few and are there any other companies that have gotten good reviews? Level Ten seems to get a good mention in magazines but that doesn't mean much either.

I think the problem with most magazines is the length of time they work with the car.... they might have it for 3 months, but the problems start 9 months in... or 3000miles but 9000 problems happen... just an assumption.

First of all I'm looking to upgrade a SC Xterra trans since I'm looking to push 325-350 hp. I have contacted Level Ten about six months ago and they said they couldn't help me at the time. I called back a few months later and the guy I spoke to said they had to let some people go and can definitelty do my trans upgrade now. I have contacted a lot of places and they're the only ones that can do upgrades that I know of so what option is left?

You must take in mind that the Supra tranny is different from yours, and while problems occur in the Supra, may not occur in yours. Have you contacted them about your tranny yet?

I'm going to go with the Level 10 VB and stall and will let everyone know the outcome in the next few months. There are things to learn off of forums but I also will say there is more misinformation than accurate information. After reading the posts on the maxima forum I came to the conclusion most guys knew very little about vehicles and were making statements about Level Ten with no or little hands on experience or knowledge. For guys trying to shift auto's like a manual and thinking you are getting better performance you are very mistaken. All that is being done is adding a lot more heat and wear to the trans with no gain in performance. Put the trans in drive and leave it there to shift on it's own. When a bunch of guys/kids are upshifting and downshifting manually with an auto and then saying they are having problems and try to blame a manufacturing then I will pass on their advice.

Acording to a couple of the spy reports on the upcomming 350-400hp GTR, the Nissan engineers were having problems with the auto tranny (same one in our Z) holding up consitantly with that amount of power.
If your looking to have more fun, instead of installing a turbo, why not install a manual tranny
...jk man. Lets not start that discussion.

Since the Maxima is FWD I'm assuming Mobiltek will not help us RWD guys, but I didn't call to ask either. I spoke with a guy directly that used Level Ten and said he had no complaints. I do have an auto but I won't be doing my trans upgrade until March or so when the tracks open again. I need to do some comparison testing on a few other mods first to see how well they work before I add another. I will post back with results if someone doesn't beat me to it.
