O/D column lever installation kewlness

Uh, Sam, hate to break it to ya, bud, but Nevada is nowhere near the midwest. It is in the west. Unless you are talking about Nevada, MO (it is real, look it up), in which case you need to swing by and say hi. I'll even buy the coffee.

Trouble on the way

You are really creating problems for yourself... you would be far better off to fix or replace the pcm. The grid heater also uses the pcm and so does the cruise control... . The 89/90 non pcm trucks used a module/controler to operate the grid heaters. Last new price on them is 300. 00 . They are discontinued now but Dodge does have a few remans left they will bleed you for.....

The 307 rears are a problem as well ! There are no more gears for them and never will be any more made by Dodge... . The housings were unique to themselves. No other gear set will fit in them... .

Sam I have one follow up question about the operation. But back up a moment to where I have a problem. My PCM is inoperative and I simply want to do away with it. I bought an 89 to have the wiring setup to follow (and the 3:07 rear) so that I can convert the 93 to non PCM. I have already installed a jury rig so that I can turn the OD on from a switch taped to the lever. But the problem there is that it is always on (or off) with the switch. Have you or anyone else used some sort of interupt so that by touching the brake or when the truck is switched off, the OD goes to OFF posistion. Something on the order of a hold in circuit that would cancel with the brake or off at the ignition/start switch. I sometimes forget this and it then is in OD as the truck pulls off in first. Some say that will kill the transmission but I have not seen that happening, just that I would like to have the interupt as part of the system you describe. I want later to add a lock up converter and would the same sort interupt to make that fail safe.



Thanks

Manual OD

Sam, I too appreciate seeing this again. This will be high on my priority list as I get the truck back together. I want to do what you did with guages in that original spot.



As so some others, I also have the mystery switch OD as my PCM wiring was garbled when I got the truck. Here is an interesting question... When I first installed the switch I could have sworn that it worked like a splitter, giving me OD in 2nd and 1st as well (when I stopped and forgot to turn off the switch). Upon perusing the FSM however, it looks like the hydraulics only permit OD when you are in 3rd. This throws my OD "splitter" idea out the window so to speak.

Now the truck is waiting the engine rebuild and I can't really test this.



Are there any transmission guys out there that can illuminate me regarding this? Anyone with the manual OD switch that want to test both theories and report?



When I do the truck late spring, I plan on installing the shift lever mounted switch and will design a simple drop out solution and post the results.



Thanks all,
