Anybody know of a single-unit o/d and l/u controller for a 518 going into a 70 challenger. I am able to wire in toggle and vacuum switches to get it to work, but not for MPH modifications. Can anybody help?

HASMAN70 I did a conversion on a 340 Challenger convertible, I used a vehicle speed sensor (vss) in the speedometer cable, I used the output to control a pair or MSD rpm switches 1 for lockup the other for O/D, I also used a Hobbs (vacuum) switch in series I was able to tailor the switches to allow lockup at 47 mph O/D at 58 mph & both would drop out at less than 2 hg (heavy throttle)

Thank you MoparAl I too would be very interested in a standalone controller. Something that uses a vehicle speed sensor and a MAP (vacuum sensor) or a TPS to control shifts like a typical trans controller would. It seems all too simple of a device, we just need someone who is controller friendly to attempt this. My car is currently controlled by switches, but this is what I had. A GM lockup vacuum switch that will go open with low vacuum, this switch is in series between fused battery voltage and the center terminal on the soleniod connector (which powers both soleniods)- I still have this functioning, it turns power off to the soleniods during heavy throttle. I also had a Rostra lockup delay module that was in series with the same circuit as above that would not allow power thru until a certain MPH (I had it set at 40mph). This was triggered by a VSS used from a Dakota. Only problem I had was the module went bad twice on me, so this I deleted. On the OD solenoid, the ground wire goes to a switch on the dash for driver control as well. On the Lockup, the ground goes thru a 5 terminal relay that when the brake switch is press causes the circuit to go open, which then cancels lockup when braking just like a normal car does, then also a switch on the dash. The only problem with this is that the speed that it engages is always the same and doesn't change with throttle opening like it would if a controller were used. With more throttle, it needs to shift later, but this mechanical design does not allow this . Hopefully these ramblings make sense 440+6 A-518 A/C 4.10s Viper Calipers Don

The article in this magazine is exactly what I made for mine, except I used a Dakota VSS instead of an aftermarket one. This kit shown was made by JET Performance Products, I don't know if it is still available. I still would like a controller with adjustable parameters whether the controller would have knobs or something done on a laptop. Just gonna have to wait Don

Thanks for the info guys. My dad has a similar setup on his 78 dodge 440 w150 pickup. The major problem with that setup is the chivvy th700r4 behind it. I'm pretty sure that setup wouldn't last a week in my car. The tinkering will be fun I'm sure. I'll also try and see if I can talk with JET a bit. Appreciate the help.

What does that setup cost?
Later this year or early next year I will have a prototype controller for the 500/518/618 RH and RE transmissions (also it will be used on my 604 transmission which is far more complex than a 518). I have yet to determine the cost of the setup but it won't be very expensive. It will provide complete control of the LU and OD features from TPS, MAP, RPM, Brake and VSS inputs. Not all inputs will be required but all will be available if you want to use them. For the RE transmission I should also be able to control the shift points as those transmission allow electronic control of the governor pressure. This is all the info I can provide about it at this time. In the mean time, the above supplied article looks like it covers most of the bases. Might be crude by my standards but probably works quite well compared to toggle switches.
Good luck!

Dartman75, I'll be looking forward to the controller if it will work like you say it will. Please keep me posted.

DartMan, what issue of Mopar Muscle is that 518 acticle with the controller from?
No clue, I didn't post that article. All I know is that there ius a controller out there from a diesel performance company buts it was like $600 and could either piggy back the stock controller or run the trans stand alone. For the volume they sell and the R&D to develop it, I don't blame them on teh cost. I don't think $600 is a reasonable price for the hobbyist. Since my free time developign this stuff is for pure enjoyment, when I put something out it's for simply the cost to gather the parts and assemble it. Should be closer to $150 USD so that people can actually afford it. The one in the above article...I dont' know the cost but I'd think it's pretty close to $150-200 and it's not truely programmable, only slightly tweekable.
I should have mentioned, the controller won't be specific to any one transmission. I don't see why it couldn't be used for any transmission with the correct settings. The micro board itself will simply allow a lot of analog signals and timing signals and control of about 8 outputs to run things like the OD, TC, solenoids. Heck, you could use it to do Nitrous control for all I care. If you know assembly you will be free to explore all kinds of potential. I will provide basic programming to allow it to operate a typical dodge transmission which will fill the needs most of you 518 users have need for several years now.

Don
don , what shifts are you talking about here ? the shifts are still somewhat controlled the same was as a 727 is , thru the valvebody , but i am assuming that the electronic governor is capable of adjusting pressure to do some controlling of the shifts ?
i do know of a unit , but its not stand alone , designed to be used on the ram pickups , no OD below 50 and delayed lockup , also unlocks the trans when you floor it , and i'm pretty sure it will also delay od and lockup when floored , connects to the TPS
running up my post count some more .

what issue of Mopar Muscle is that 518 acticle with the controller from?
It's from the now defunct High Performance Mopar magazine, the June 1999 issue. It's the last part of an eight part article that began in March 1998.
