Adding 4 low and neutral position switches to late 60 series Tcase from FJ62 Tcase

[dbbowen]

Has anyone here done this and know whats involved with it? My case is machined flat where the two sensors go. Im assuming the holes will need to be drilled and tapped but does the shift fork inside the tcase have the little grooves on it to index the switches? Anything else involved?

Im trying to use the Neutral switch to run my AT P light on the fj62 shifter im putting in my fj60 and the Low range switch to send ground to my 5.3 PCM to tell it to enter the 4low tune and trans shift table.

Thanks

Can't help with the modification of the case, but curious about implementing the low range tune and shift table. Did you have your tuner enable that? Or is it typically something that is included in the base tune? I see C2:16 is the signal for the ECU (geniii) so assuming that just needs to be wired?

Adding it to my list to have my tuner look at if I ever get around to getting mine tuned.

Have you thought about using detents or other switches outside your case on the levers themselves? I mean hell you take the case apart every week it seems so you could try to swap it for a drilled case

The low range table is definitely tunable you can tell it what gears to hit and when to shift. Im hoping that i can just send it ground and it run better in low... but i might need to take it to the tuner and get them to set it up some. My approach was going to be get it set up to have c2 16 receive ground and see what happens first haha

You can wire it to a switch to send the pin on the pcm Ground, im just out of places i can mount a switch so i was thinking using the low range sensor on the 62 case would be the best bet. I talked to Kurt and he was saying its pretty involved to add them to a 60 case unfortunately but since you have a 62 you can probably do it. It looks like its sending power so you could pull from this wire on pin 2 here and use a relay to send ground to your PCM

i havent thought about that. I might give that a try. The 80 series case has a low range sensor in it too so i might just put this project on the shelf until i swap over to that one
