So lately ive been thinking about supercharging my 2001 20th anniversary, in the same thought process i was thinking about tranny cooling and what not. So my question is if I were to upgrade my automatic transmission cooling system how would it hold up with a supercharger. I would swap in a manual tranny but its not a necessity at the moment since its a perfectly functioning trans. I want to make this car a bit more fun also i want to be able to spank on g35's and keep up with the 37's

 

Im not knowledgeable enough on the 5th gen SC options but I would at least think about a VB upgrade. Tranny coolers don't drastically cool the tranny fluid as advertised and really the stock cooler within the radiator probably does just as good. I put one on because I upgraded my rad and they only had performance rads for a M/T and so I had to put on an aux cooler

 

Well...despite what ShocknAwe says a VB mod will only increase the temperature of your transmission which is why people put in coolers when they get a VB mod.

The VB mod will help with shifting and providing some durability, but you'll need to add on a tranny cooler. Do some searching on VB mod and see what size tranny coolers people are using. You want to be sure to size it right.

 

what is a VB mod/upgrade im a little lost sorry for being such a noob

 

I would post your question in here maybe: http://forums.maxima.org/supercharged-turbocharged-38/

 

VB stands for valvebody. Basically a shop with expertise will modify the valvebody of the transmission for quicker/stronger shifting. Typically they are modified in stages where each progressive stage is a harder shift, but heats up the transmission fluid to a higher temperature.

I had a VB mod installed on my 2K Maxima years and years ago. I don't even remember the size tranny cooler I use, or the vendor I went to for the VB mod. These days I'm not sure what the VB mod market looks like.

Good luck, but check out the turbo/supercharger forum as someone else suggested.

 

aha I figured thats what it was I just didnt want to jump the gun and assume something else well I have to head out to work in a bit thanks for the speedy replies guys any input is appreciated

 

any moderators you think I could PM about this to get the move done? thanks

 

All you need is a tranny cooler and the VB mod, and your auto tranny will hold up just fine.

 

yea those were my original assumptions, now the thing is to locate a shop in the tristate area thats knowledgeable and trust worthy with this type of work

 

lol @ postin in the SC/Turbo section, *dead crickets

 

so I did some digging around and found that stillen has a vb kit, but I saw mixed reviews which is always going to happen but after that i went on their site to see if they sold it from there and its not listed maybe i have to call in or simply find another manufacturer. im liking the hp #'s i see over the net espeically with this one i was really impressed cause my car has 172k on the clock and this one has 163k but it was a few years back

 

Hang on I thought the valvebody mod was the drop resistor change or something. The valve body people are speaking about here is the Trans-Go kits. They change the springs and other internals in the control valve assembly (valve body) to allow harsher 1-2 shifts. 2-3 is not as harsh as the 1-2 but still more noticeable versus stock. The theory behind that is the luxury feel of the soft shifts comes from the trans holding line pressure a second or two to swap gears. The trans-go kit eliminates that 'lag' so it’s literally a SLAM into 2nd gear. You will probably need to look at your motor/trans mounts if you go for the trans-go kit. I believe people go with the urethane mounts to soak up some of that harsh shift shock.
