I'm programming an idec smart relay to run my transmission using an up down counter. I get ocassional switch bounce. I will be using the relay to run the tcc lockup also. It's programmed to turn on with one input and off with the same input and both shift inputs. I'm a little nervous about the tcc unlocking in time. My question is if I set a short time delay on the shifts to be sure the tcc unlocks in time will this also fix the switch bounce problem? If not any other ideas on de-bounce?

Way over my head, but I would be intersted in the finised product. There was another member already selling this type of controller a while back. Dont know who it was, but I think it was $700 or so

thanks stu. I'll have to try and figure out what all those symboly mean. Is that last one an OR gate? The programming is pretty simple and I'll gladly share but it's hard posting pictures from my iphone. I'll borrow a computer when I get that far. The smart relay was $125 plus switches so it's a pretty low investment so far.

For what it's worth, I added a .3 second time delay to all the inputs and it seems to have worked. I could probably shorten up the delay time but it's tolerable and hasn't skipped shift yet. I also bought corvette paddles which have boards built into them. They may even stop switch bounce. They are pretty neat. Push to shift up and pull to shift down. I don't actually have this working in the car, it's just on lights right now for programming.

I finished programming the torque converter lockup and I'm happy with the way it works. Pushing a momentary button turns the tcc on and off with no delay. Using the shift buttons the tcc still disengages instantly and the shift is delayed .3 seconds. I have been driving a 4t65e with a ratchet shifter and shifted with the tcc engaged and I don't want to do it again. The earlier transmissions may behave better. Weather sucks here but I'll be working on mounting the paddles and giving this a try. For those interested, e-transcontrol also has a computer setup for $400. I'm confused about it actually having line pressure control so I don't know if it's a better solution that mine. Like I said earlier I paid $125 for a smart relay with a built in display so nothing else is needed for programming. I'll draw up a decent diagram and post it in case someone else is interested.

I drew out the diagram but can't post from my phone so if someone wants to post them for me I can email them. Something to keep in mind is I don't have a pwm output for line pressure control but after the fact I found a super relay made by idec which does have pwm. I also don't have enough outputs left for a seven segment display. I am looking into this problem and may need to order an expansion module for more outputs or figure out how to use the display to show gear position. I could mount two lights to indicate which solenoids are energized but thats the last resort.

Ok. You'll have to pm me your email address. I spent a lot of time and money on the ratchet shifter so it will stay but I won't be using it really. Just put it in drive and use the paddles is the plan. I also decided on installing some lighted numbers to indicate what gear I'm in. I can use relays off the outputs I already have. It's not as fancy as a seven segment but it should get the job done.

When programming it starts on the right at the output and works left. Q2 has a redundant on/off with 0 on and 2 off. Everything is set at retentive so there shouldn't be a problem but I left it anyway. Q1 has 3 set on and off. I'm not sure why it worked out this way, 3 on and 2 off didn't work for some reason. Also all the on/offs are 1 gear off. This leaves the counter at 0 is first gear to prevent shifting lower which would cause a 1 to 3 shift. Probably wouldn't be good. Be sure to check your trans logic in case it's not the same as mine.
