Hello,
Just wanted to show you how we're working in the manual to auto swap.
Why auto? Because as my truck is not EFI I need a standalone computer to control the tranny, so I can configure it to my taste.
I'm going to use a SupraStick computer to control the tranny, being able to choose between two automatic modes and a full manual mode with overrev protection.
As I've a Momo steering wheel I'm going to buy a thing like this to have shift controls in the steering wheel:
Also I can put a simple 16x4 display and monitor the speed, the RPM, the TPS and gear engaged.
This is an A343F auto tranny out from a 3.0TD Hilux Surf. Also got the TC, flywheel, bellhousing and shifter, got it from Richard (stormforce) thanks!!!
The A343F it's almost identical to the A340F, I think the only difference is some gear ratio.
Nice thing of being a "F" series is that the tranny isn't a part of the tranny like in the A340H's found in the States' 4Runners. This means it has a standard V6 pattern so I can put my chain driven T-Case or put duals in a future.
Have you seen the fancy customized short sleeve coveralls my friend has?
The T-Case it's almost identical to the chain driven ones on the R150F manual trucks, but we're going to use mine instead of this because this is an electric actuated one and the motor would interfer with my parking disc brake. Also less electrics, less problems. Nice thing of those electric transfers is that you can have a "dual shifter" with only a switch.
This is the shifter linkage
T-Case actuator. Only has one rail for controlling the ratio.
Bellhousing
Parts we are not using. The throttle cable and cooler tubes. I'll use a big cooler in front of the radiator and will be blocking the throttle cable in WOT position to have the tranny pressure always high. Will make a little noise when idling and will require a bit more brake pedal in the red lights but will make quickier shifts (Cooler ATF, more reliable tranny).
T-Case and tranny coupling
The electric tranny we're discarting
Pulling the tranny pan you find the filter
Pulling the filter you can see the valve body and the solenoids. Two for the shifts and one for the TC lock-up.
Lots of bolts!
This is the valve controlling the tranny pressure IIRC.
Those are the shifting accumulators. From left to right the 1-2, the 2-3 and the 3-O/D.
In the 1-2 and 2-3 accumulators we're going to do a mod the Supra guys developed. It consists of shimming the little springs so more pressure is achieved. This makes the shifting quickier and harder. The Supra guys had excelent results with this mod and they've engines developing +450HP...
Here is where the shim goes
This accumulator will remain stock as the shifts you want quicker and more used are the 1-2 and 2-3.
Valve body detail.
This is the shifter rail
Hope you like it.
I'm going to order the tranny cooler and the SupraStick.
