The trans is a 46RH also called a 518. The only electronic's is the OD solenoid. It is controlled by the PCM mounted behind the battery.

The trans can handle around 300 HP or so easy. The stock converter can't hold that much. It was made loose by Dodge. The best improvement you can do is to replace it before doing much to engine HP.

Ok so finally got it going and got it home...(the battery cables where bad) but OD does not work, so can somebody tell me how to wire in the switch? this truck is a worn out pile and there is wires hanging everywhere so it is a little confusing. I'm not planing on fixing it up but i need it so i have a rig to drive as my chevy just got totaled.
Thanks HP Freak

Is the charging system working?

There is a switch in the front trans cooler line.It is located by the front of the trans pan, driver side. If the wires are off it the OD will not work.

No the alt. is bad. does that make difference? I checked the switch on the trans cooler line and it is plugged in. Anything else?

Don't bet on the alt being bad. If the PCM doesn't see a RPM reading from the crank position sensor it will not turn on the alt/ A/C, OD, CC.

Check the air gap on the CPS. It should be around .050". It is mounted at the 11:00 position on the harmonic balencer. When looking at the front of the engine.

Ok so i got it working right... Thanks guys!!!!!!!!! But now i'm playing with the IP and was wondering how far i can push things before it starts breaking things, it is totally stock . Is all i have is a boost gauge so how much boost can i build with how much smoke before things start to give.

When you start turning up he fuel there are 2 more gauges
Pyrometer - it will last a long time below 1200 deg, hotter is less life. A kit is a little over $100 and repaired seems to start around $650
Trans temp - start thinking of parts when it hits 250 deg and thinking of changing the trans fluid a little early, over 300 F put it on the 'to do list'.

The converter will probably break if you turn it up and beat on it, might order one to have when it does. If you want HD parts get them also, the seals and standard auto trans parts are everywhere.
