The diesel that you imported?

I think the 95+ ones have a variant called the A343F which is pretty much an A340 with a full time transfer case with a viscous coupling.
Does anybody make a standalone controller for these trannies? Would love some input! Thanks
Check out Radesigns Products Llc - Shift Controllers. Not a standalone controller but does give you the option of choosing your gear if that's what you looking to do. They have a couple different solutions to fit your needs. I'm thinking about doing one myself.

Yes. I move through cars very quickly, it's a disease.

it sure is. you dont even get enough time to enjoy them.
Get a manual, that's how you control the trans. No pink milkshake, downshift going uphill...

This is for a super secret project. You're preaching to the choir when it comes to manual v. auto.

More than one way to overcome that. I built a controller so I can shift my auto just like a manual.

I run a SupraStick in mine, as the V8 ECU wasn't compatible with the 4 speed auto box.
It works well, and has done for over three years!

That's great to hear! Was it difficult to setup? What sort of signals will I be splicing?

As per PM, but for the sake of forum search 
I thought it was pretty easy to wire up, Instructions Here
It basically operates on throttle position vs vehicle speed, so splice it into the speed sensor on the output of the gearbox (Pre transfer box).
RPM is also there, but its only really used for a shift light and over rev protection.
It took me a while to get my shift points where I liked them, and I redid it when I re geared to 4.88s, but it's treated me well over 3+ years.
Attached is my last map.. this is for a truck running a VVTi 1UZ, 285/75/16 and 4.88s. I might tone down the kickdown kinks at about 20% throttle a bit in 3rd and 4th, but I've got used to it now.
For the record despite my work, my truck runs a factory A340F gearbox, the only mods are:
I used the Pre transfer box speed sensor, so it still works when in low range.

- LS400 Bell housing
- LS400 Torque Converter
- Early (4 Speed) LS400 oil pump/input shaft
- Early LS400 O/D unit (same ratios, just made fitting the oil pump/input shaft easier)
- Overall line pressure adjusted to be higher (help with slippage and oil temps)
- Shift Accumulators shimmed (help with slippage and oil temps)

How are you measuring TPS? My DBW pedal from the TDI has two potentiometers, one rising and the other falling. I just don't know the voltage output of these sensors. If the range is outside of acceptable for the SS, do you know of a universal TPS that would work? This might be a better question for the Latent, but I fig'd I'd check with you in the meantime.As per PM, but for the sake of forum search

So in terms of "SupraStick" the application is the same as a stock 4Runner.

Well what we do know is your awesome projects get us hyped up for us all to be let down.

I put myself in that group. An unexpected pregnancy, and the allure of importing, really slowed me down last time. I'm not going to make any promises, and am also not going to post anything until it's finished, as I learned my lesson last time.

I've been there. Was just giving you crap. Can't wait to see.
