cheers hero i had a look for plc's on ebay, are they easy to program or would a normal ic be better? i have never programed anything before. i contacted a few company's for a quote to build the unit and it's around $5100 aud, the solenoid speed will be fast but i should be able to adjust the speed via voltage but no one seems to stock the large units i need. i have been looking into pneumatic rams and it would give better control plus they are dirt cheap.

found a problem i'll need to add a third solenoid but shorter solenoid above S2 (easy as) so it go to a neutral position so the firing order will have to be FIRST S1out S2in SECOND S1in S2in THIRD S1out S2nil S3in FOURTH S1in S2nil S3in FIFTH S1out S2out REVERSE S1in S2out

i have a crappy gear selector that i want to change i know what i want i know how it should work i know it will be safe i don't know how to build the electronic as you can see in the pic it's a simple design to keep it reliable it uses the 12v acc power to power the unit but i'm thinking it might be better to use the 12 batt power to run the solenoids via internal or external relays, i'd prefer internal the safety must be pressed or pulling the stock/modified shifter will do bugger all i was thinking of two industrial momentary switches telling the what ever to fire off the solenoid, i also want the what ever to have a delay of 1-2 seconds before it can fire off the next solenoid so the box it not going to miss a gear and blow up, it's a light truck gear box but still it's $1500aud to repair the what ever needs to fire to two solenoids in a specific order to go up and the same order in reverse to go back down it's like a tip tronic/paddle shift system without the pagani zonda hanging off it so i assume you are all still with me do you have any ideas how to make the what ever and help would be awesome
