ok then, i think I might be able to fit them all in, I have just received the GPIO board and megashift kit, so I can start work on the development of this.

Just need to read up on the code, and I will be away, Can you recommend any good books Lance?

Because P N and R all use the same solenoid output, could i put all on one input. Then 4 and 5 on one, 3 on one , and 2 and 1 on one input? something like this

Lance, you are probably correct. Theose inputs are from the auto. To get 1st gear, in logic, you need 2nd from the auto and 1st from the selector.

ie. in operation to get first you pull the shifter back to 2nd then across to 1st. same for 5th back to 4th and across for 5th

the shift pattern looks ...

Lance, I have attatched a PDF (Finally worked out how) of the shifter inputs, PRN431 are direct inputs on their own, 5 and 2 require 2 inputs (4 and 5 for 5th gear, 2 and 1 for 2nd gear)

PS I have added the table from last week as an Exel file

Yeah sorry bout the table, tried to post it as a picture, but not successful. I have converted it to pdf, but cant find a way to host the file. * EDIT * - I have added it as an Excel file

As for the shifter inputs, I have P/N on one input, then R, then D. Need 4 more inputs, and only space for 2 ...

I have done up a table for the MegaShift hardware and how it will work in my application

MegaShift.xls

it all lines up fine, except the 4,3,2,1 inputs to show when manual selector is each low gear, need to find 2 more inputs or I need to find another way of inputting 7 signals on one channel.

I ...

Lance, The lock up feel parameters are very similar, I think that they function exactly the same as the variable shift solenoids for 4th and 5th in the a750. I also dont think its needed, i am more worried about burning the clutch or band, than undetectable shifts on the highway.

Although, because ...

Righto, I have delved a little deeper into the transmission side of things. Looks like it needs 3 general on/off outputs for first to third gears, 1 normal pwm for the torque convertor lockup, one inverse pwm for the line pressure control. 4th and 5th gear uses a variable solenoid (same construction ...

hello, just wondering if anyone has used one of these GPIO (MegaShift) controllers on the 5 speed toyota A750f, (or any toyota transmission), it looks to have seven solenoids and several look to be PWM. I am yet to locate much info on this transmission, but I have come across this PDF http://www ...
