Sorry, I don't mean to be lazy, I just figured someone had it handy.

I'm really thinking about getting this since the TCUGO is no more. I read the review provided in the link. How do you change gears? Just use the stock gear select?

 

[TSIMonsteR]

I am confused about that 2. How do you change gears?? So L would be 1st, 2 would 2nd, and drive is 3rd? what about 4th and OD as 5th?

 

[Rob10_99]

we are talking about two different things,

TCUGO= manual car(with selonoids to make it paddleshift)

vs

black box= automatic car(to keep the car in what gear you have it in)


right?...

 

[emitsu97]

Direct form the Ebay listing:

"...What this module does is it allows the driver to manually shift through the gears on their stock shifter in an aggressive fashion. This module will increase the shift firmness, the shift quality, and the rate at which the tranny shifts into gear. Shifts will be instantanious and firm when shifting manually with this kit activated...."

In my excitement I didn't "absorb" the whole thing the first time I read it . I'll be buying one the moment I get back from lunch.

 

[emitsu97]

Just bought mine.

To further clarify, while the TCUgo and this box accomplish the same end goal (ability to select which gear you're in; sequential shifting), they go about it in different ways. The TCUgo is a replacement TCU. It controls the line pressure in relation to the throttle position, as well as allowing the driver to change that pressure. There is also supposed to be some protection built in to keep the car from shifting into a gear it really shouldn't be in (3rd gear at 6500 RPM, the car won't be happy if you shift to 2nd). There is also the wireless 'paddles' that can be mounted wherever and the gear display.

That's not to take away from the Ebay box in question. It gets the job done, albeit with less flair, for a fraction of the cost of the TCUgo. Hopefully that clears up the differences.

I'm still confused. On my shifter, I have 3 go forward options. L, 2, D.... thats only 3 gears.

 

[emitsu97]

The AT's only have 4 gears. OD is 4th.

 

[squeak104]

And 5th "gear" is the torque converter lockup.

 

[maui6651]

Our transmission's shifting is controlled electronically; the TCU sends signals to the solenoids which divert fluid through the valve body and transmission, which in turn controls which gear your in.

The car also has a method to mechanically control the valve body operation via the shifter. None of the electronic boxes available use the stock shifter because it uses a mechanical connection. Rather, they use a seperate electronic switch to move through/select the gears. As long as the shifter is in drive, the electronic switch can select any of the 4 gears.

im still confused. So with this box.... say I want to be in 4th gear... how do I do it?

Put your gear selector in Drive and make sure the Overdrive button is on. There's 4th gear. The Manumatic Box does not have the ability to control torque converter lockup.

Not true in the case of the Manumatic Box. It supplements the stock shifter in two manners - first being that it increases the fluid line pressure in the transmission to its' maximum, second being that it adds a sort of "Hold" function while engaged, that keeps the transmission from shifting out of the selected gear.

The main reason why the Manumatic Box is more efficient than "manu-shifting" with a stock transmission is that the pressure in the lines is increased, allowing a harder, faster shift than the stock TCU will allow.

I was under the impression that some people were thinking that the manumatic box somehow used the stock shifter (the lever, not the TCU) to shift, which isn't true. The stock shift lever is used to select P-R-N-D, and the electronic switch allows the driver to select 1st, 2nd, 3rd, or 4th gear.

I was going to go tcugo but i guess i'm not now which sucks but for now (since my tcu died) i just rigged up the toggle switch shifter and try to make sure i pick the right gear. I just have to pay attention now i guess. This mod is still badass though.

 

[staticbrainwash]

I didn't think this all was that hard of a concept to understand.

And i assume this just isn't going to happen anymore, which sucks.

Someone needs to re-invent this, because the a/t world needs something cool too.

It's as simple as figuring out what wires need what signal, at what time, and creating a circuit board to do just that.

Its' not as simple as it sounds, though. Someone'll figure something out, I"m sure.

I wonder how you project is coming up... Any updates?

 

[Dorifto]

I've still yet to swap my other shortblock in to get my car to a driveable status, but when I do, I'm going to chase wires and pinouts, and drive around with a multimeter hooked up to different wires, and see what voltages/resistances run to which wires in what gear, as well as TC lockup. Once that's figured out, I can go about figuring how to shift the car via paddles.

Also a little thought of mine, is a Tiptronic style slap-shift, might prove interesting.
