Re: 1st gear issues with 5.015

Lance,

This is the 4r75w ford trans behind the 2v 4.6. I was having the speed sensor problems originally, but got those fixed.

I know that P, R, N and 1st all have sol A on and B off, which tells me its mostly mechanical between them.

1st gear issues with 5.015

Ok, I don't think I had this issue with 4.039 when I had it loaded. But over the last 2 days when I loaded 5.015 I've found that 1st gear is not operation like it should. It does not shift according to the shift tables (you can see in the datalog on any acceleration from a stop that it will not shif...

manual shift options?

After getting this Ford 4R75W trans working pretty well, I have started to lean on it a little harder to see how it performs. On my truck I currently have a Lokar shifter setup and no electric shift buttons yet. I do plan on creating some sort of shift paddles/buttons down the road, but I would like...

Re: speed signal issues

Well I got it fixed! :D Based on what I thought it was doing I went ahead and put a 10k ohm resistor in. Originally I thought I would put it on the VR side, but decided to try it on the digital side inside the GPIO case before it went into PTO. This fixed everything....the signal is smooth, quick an...

Re: speed signal issues

What I did for the digital input to gpio is bring it in through pin 14 for VR3 input, because I do not have any circuits on VR3. I then grabbed it on the board and jumped the wire right to pt0 (I believe thats the port number, but can't remember off the top of my head...whatever the jumper is for th...

Re: speed signal issues

The dual vr board is the one that is sealed, not the gpio. I just wanted to be clear as I reread what I posted and see it may not be. Gpio is not sealed at all. The dual vr board after everything was soldered was sealed in dual wall heat shrink. I got the idea from Jean to do it that way.

Re: speed signal issues

I inspected the vr board closely before sealing it off so I don't believe there is any issues. I also scoped the VR signal which was nice going into VR board. I have not scooped the signal coming out yet though. I just moved the signals around from ms3 to gpio and had no problems on ms3 and nothing ...

speed signal issues

I've been having issues with gpio dropping out an loosing connection with TS and MS3. I figured out that all my connection issues were from the OSS input to gpio. Here is my latest piece of info and where I'm at. The original circuitry for OSS was not even close, so instead of playing with it I put ...

Re: MS3 with CAN pass-thru issues

A little update from last nights testing. I was able to get CAN VSS to work. I think I might have something going on with the OSS signal, so I took what is actually my VSS2 (tested to work perfect) and changed it to VSS1. This is a front wheel speed sensor, so its not ideal, but I figured it would d...
