Auto tranny drop resistor mod questions
Whats the thinnest wire I can safely use? Whats the lowest amp rating switch? I took a look at the wires and they look pretty thin. Maybe 16 or 18 gauge. I know someone recommended a 20a switch. But those are so big. I want to be able to use a small 3A toggle. Is this safe?
How about hooking up some type of micro switch like in the nitrous kits to the resistor? Have normal shifting while regular driving. When you go WOT, have the resistor current disconnected and go full line pressure?

16g should be about right. i used speaker wire and didn't have any problems. as for a switch, go with a 10a automotive switch.
your idea about having a window switch isn't a bad idea, but a regular switch would be just as effect and easier to wire.

I beg to differ on the ease of wiring. If you hook up a micro switch to the throttle, no wires have to come in to the cabin.
I just haven't found any microswitches that have that high of an amp rating. Thanks for the info on the wire and the switch. I guess I'll look for 10 amps. But the WOT switch would be sweet.. =P
I don't know much about relays. I just read up on it quickly on the web. I'm still a bit confused on if one could be used in this application. Any input would be much appreciated.

But I think quite a few people on this board have this mod hooked up to a switch. With my idea the resistor will only be bypassed at WOT.

Do the math yourself, it's a sure way to blow up your transmission.
Double "A" MCO have their # handy.

I do have a modded VB in there now. I'm not sure if it goes full line pressure though. Maybe you're right.

The problem is the 1-2 shift isn't as fast as I would like. Maybe I got a bad VB from Don. Who knows. Under normal driving it shifts fast. But not at WOT.

You should have nice clean crisp shifts then. The dropping resistor is there to limit line pressure only during the shift. Once the tranny has shifted, it goes full line pressure to hold the clutches together so they don't slip. Again, that happens after the shift is complete.

What I was thinking is.. VB mod makes the tranny shift at say, 70% line pressure. Resistor would make it shift at 100%. I don't think VB+Resistor mod=170%. I think it would still be 100%. I'd essentially end up with a sport mode tranny when at WOT.
5-speed swap might be in the future. But not near future. Job market is too unstable. I don't want to drop such a large chunk of change in to something that isn't broken.

The reason I started thinking about the WOT switch was because I didn't want to worry about accidently flipping the switch. Or if someone else drives the car, them accidently flipping the switch. Why wouldn't you want full line pressure if you're going WOT anyways? Were you suggesting a arming switch on top of the WOT switch? Kinda like a valet mode?

70% is just a number I pulled out of thin air. I have no idea how much the VB bumps up the line pressure. I would think the stock shifting line pressure is pretty low since its so buttery.

I follow and agree with what you're saying, except for the 70% part. Where are you getting that figure?

the debate is out on if it causes long term drive train problems because of the excess power being shifted through the transmission. Lime is correct in saying it does not cause problems if only used once in awhile. obviously this is not something you use to drive around town in.
Zumble: does the VB work in the same way the drop resistor does? i believe they both apply more line pressure to the shifts. basicially its similar to Maxximum Tuning's VB mod. they have a street and track configuration. the drop resistor is more similar to the track configuration.

I don'k like the switch at the track because I have to remember to turn it on and off all the time and its just one more thing to forget. I don't like using it at part throttle so the WOT switch will be fine. Thanks for the idea.
#22
Works out for you because you engage the nitrous with your hand right? You can probably use the microswitch that came with your NX kit.

Ya, you are right its not that often I go WOT anywhere but the track so its probably ok.

Maybe you should contact the people at mobile tek and ask them if the mod bumps up the line pressure...rather then just guessing.

I do think that if you are going the resistor route, a window type switch would be pretty cool to have since it would allow only WOT engagement.
Way to use the ol noggin'....

From what I have heard the VB mod is somewhat less than full line pressure but what % I have no idea.

I went to radio shack. Got the microswitch and a relay. I may try to hook all this up tonight or tomorrow. =) I'll tell you how it goes.

Sounds good. I have a radio shack dual position relay hooked up to the drop resistor right now. It's holding up fine in the closed position. I put the relay in the front relay box by the driverside headlamp. No problems, the car is shifting normally. I'm going to see if I can get that WOT switch. When I apply 12v to the relay, it should disconnect the drop resistor. =) I think you said the OD light flashes when the resistor is disconnected? So we get visual dashboard confirmation when the mod is in use =)

Jime, was your CEL also like this? there are times when i'd use it and the CEL would come on and then randomly turn off sometime later and other times when i use it, it doesnt turn on and if it did, it would be later on in the day. of course i'd only leave it on for 30 seconds at the most.

Okay guys, I won the auction for the NX WOT switch. I need to know where to run power for the relay signal. I'm probably going to use the WOT to provide ground to the relay. Right now I have the relay hooked straight up to the positive terminal of the battery. Probably not a good idea in the long term right? The wires for the signal terminals in the relay look really wimpy.

For those guys trying to compare the max tuning vb mod and the resistor, it's like this
I currently have a Stage III VB from max tuning... 1-2 is snappy, but not neck wrenching, 2-3 is slightly quicker, but still sorta laggy... but definately an improvement.
I'm also boosted.
I pulled the drop resistor and did a full run to 130ish? before i got scared...
I spun/chirped 1-2 hard. 2-3, chirped hard.... 3-4(OD?) Didn't notice, was scared ****less driving on the highway.
Either way, the feel that I get between the two shifts is this. If you want quicker shifts, resistor mod hands down. The thing is, when my tranny shifted, it didn't feel right... the tranny just literally slammed into the next gear, throwing the car forward... it sorta just went "clunk" into the next gear.
If I were to actually do this switch mod, it'd be a track only mod. There's no way I could possibly drive at full line pressure through all gears.... with the vb mod, the higher the rpm, the harder/quicker the shift. With the resistor, you can be at 1500 rpm, or 6300, and it shifts just as hard.
One thing to note though, it's probably better for the tranny to have full line pressure in 2-3, and 3-4(if i actually need to shift that high at the track) because the vb isn't as quick as the resistor mod in those shifts.
Yeah yeah, i'll convert soon.

Not using a manual switch. Using a relay and a WOT switch.
