how do i tell what trans i have on my 94 ram 1500 2wd 318, it is the h/d with tow package and o/d switch trans cooler... not sure if that helps just wanting to familiarize myself with this rig

 

Should be 42rh, known at parts houses as A518. Someone correct me I I'm wrong.

 

46rh.

 

46rh, think I miss-typed earlier, not sure can't see what I typed.

 

Yep. 46RH.

 

that is what i though when i saw you tryped a518

 

thanks guys changing my trans fluid today anything special i should look for or expect?

 

be sure and use ATF+4 or whatever your recommended fluid is for your 94. +4 replaced +3 and the other number??, something like 71xx??

put in a drain plug while you have the pan off. Dorman 65241. i put my plug in the bottom, but on a buddies we put it on the side so nothing could hit it. it doesn't have to drain all the fluid out, just most of it. be careful of placement not to hit any internals.

the way i drain one w/o a plug is to loosen the pan bolts until it starts running out everywhere, then let it drain awhile to drop the fluid level down to the pan seam. then slide a floor jack under it and put just a little tension on it. remove the rest of the pan bolts, then with several hands, lower the jack while balancing the pan. other methods are prone to bending the lip of the pan.

when the pan is off, place it upside down on a piece of wood and make sure the bolt holes are not indented. if so, hit each one with a hammer to flatten it back out.

While you have the pan down, check all the wiring harnesses in there for worn/broken wires. Some have a tendency to rub the insulation off, and short to the metal parts.

Pay attention to what's in the bottom of the pan as well.

 

ok speaking of which... is there anything i could look for down there cause my od switch dont work i got my fluid and gasket filter...but weather has been crappy so not sure when i am going to get a chance to do it. But i would really like to figure out whats wrong with my od and why i cant turn it off i got a new switch (no luck) i got a voltmeter on there and it has power comming in i heard of just wiring a toggle switch but not sure which wires to hook up?
