Increased performance for automatics

Is there any way to make the automatic in the Maxima change gears more aggressively. What are the best performance upgrades for an automatic. There is such a huge desparity between the stick and auto Maximas I was hoping there was some way to close the gap. Thanks in advance.

Valve Body Mod(AVOID MOBILETEK.COM) then a Torque converter.

I'm going to get the Valve body mod when I get the money.

I wouldn't recommend the drop resistor mod.

I would definitely recommend you read the stickies at the top of the 4th Gen forum - there should be plenty of info. up there regarding these mods. Welcome to maxima.org.

JWT sells a TCM for the auto tragics... i have been looking into this since its cheaper than the valve body mod and basically does the same thing.

It allows you to have 3 settings (stock)(street performance)(racing) Instead of increasing line pressure thru the VB it does it electronically somehow...

Dont really know too much about this thing since i am saving up for a tranny swap instead.

I would get a stage 2 VB mod and a high stall TC. The TC goes for about 400-500.

nothin wrong with the DR mod as long as you get a tranny cooler. i've been running it without a tranny cooler and have had no adverse affects (not trying to make this into a which is better arguement)

My brother used to have a 1990 300ZX NA automatic, and he scored a part called an ALC (automatic line controller). I believe he got it from Stillen. The thing worked like a charm - ran until redline and then *bam* into the next gear. Unfortunately, I think it was a part for Z cars only....

Just manually shift it, You can take it to the rev limiter if you just hold it in 1st 2nd then drive(OD off) then OD on

I was driving with my friend's A4 yesterday at and he decided he wanted to open it up. I tried that overdrive trick and I was flying. We slowed down when I was doing around 120. I noticed that there was a strange smell though. I wasn't sure what it was. I never did it agian during our trip, but I was wondering if anything like this happened to anyone else. Thanks for all of your comments, you guys are really helpful.

I was running the VB mod on my 97' SE. Its creates a more agressive shift and helps close that gap "a little". I would also run the drop resistor mod once in while. I didnt like how rough it felt on the trans so I really only ran it for fun every so often.
VB mod is a good investment, but if you are still near stock the money might be better spent elsewhere

why bother, you've already made up your mind, you found 2 examples in that thread that have been doing it, then theres other examples that are contrary to it. id just play it safe and not want to blow my tranny, i guess that risk is more than worth it to you.

Manually UPSHIFTING will not harm tranny at all. Manually downshifting can harm tranny.

THe examples that are contrary are probably missing something like "yea he manually shifts, but he shifts from neutral at 6.5k rpms into drive"
