DanielCPG Posted December 17, 2020 Report Share Posted December 17, 2020 Hello. Looking to see if anyone can design some logic for my application. The short story is Ive got a 4 speed auto trans that has been modified to Shift Up a single gear by grounding a wire and shifts down one gear by grounding another wire. I am using a pcs push button shift module between ecu and trans I want to get an output to make the trans shift from 1 2 3 4 / 4 3 2 1 automaticcaly based on tps/speed. I was thinking to make a table that with tps and speed as the axis and the value in the table being the desired gear. Then use the output of that table as an axis of another table to trigger shifts. Keen to see if it can be done Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 17, 2020 Report Share Posted December 17, 2020 Is there any way for it to know what gear it is currently in? Does it always start in 1st when powered up? Does it always need to go back to 1 when stopped? Im busy for a couple of days but might be able to have a play around on the bench in the weekend.

DanielCPG Posted December 18, 2020 Author Report Share Posted December 18, 2020 The unit monitor and display the commanded gear. I have emailed then to see if i can get the can information as i believe they can intergrate with there own modules. When put in drive the unit starts in 4th. I can see it would be problematic syncing the links expected gear to the units unless we can transmit it accross somehow https://www.powertraincontrolsolutions.com/Performance_Aftermarket/Products/Electronic_Shifters/Push_Button_Shifter/ Quote Link to comment Share on other sites More sharing options...
