I've got a small problem. My 92 Runner is a V6/auto. I replaced the trans with a rebuilt one out of a '91 P/U. When I did it I was an idiot and I didn't use my sensors and electrics. I used the ones that were on the trans when I got it. Now...it seems to drive OK in 2wd (although it did do a wierd lock/unlock the torque converter at 70mph thing a few times). My reverse lights do not work and the 4WD is not engageing. The t-case drops into low range but the ADD does not engauge and I don't get the green 4WD light on the dash. Of course I already got rid of the old trans. I'm not sure what sensors do what on the trans so I'm a little lost.

Got any ideas???


Thanks for the help.

Did ya re-attach the 2 vacuum hoses to your front diff? Also the green 4WD light will not cause the system to not work. It is just an idiot light. I never reconnected mine when I SAS'ed it. Check to see if all hoses are connected and that there are none hanging down or cut.

I did redo all the vacum connections and wire tied them. I originally didn't think anything about the 4WD light not coming on because I figured it wouldn't effect the function. Then I got the truck out in the dirt and found that my front wheels weren't pulling. So...anymore ideas???

Have you verified that the transfer case is engaging when 4WD is selected?

If so, permanently locking your ADD is simple, there's a link off my page in the Mods section.

I did make sure that the t-case is engageing and I have a set of Asin hubs in the garage so I may go that route.

someone has to have an idea????

ADD is automatic hubs, right? Why not just convert to manual?

This has nothing to do with your hubs. You don't have them anyway, you have flanges that permanently lock the wheel/rotor assembly to the CV. They don't lock/unlock at all, they can't.

Priest, I'd make absolutely certain that your t-case is engaging. Put the truck on stands and carefully double-triple check. If the t-case is engaging and the front DS is being powered, I would take that ADD actuator off, lock it, then reinstall it.

You could easily have 2 vacuum lines switched, which would prevent the ADD actuator from working. This mod takes just a few minutes and you'll wind up with 15 ft of vacuum line removed from your truck; a little more space in the engine bay; and a simplified 4WD system.

But really check that t-case. It uses clutch plates which can wear over time, and there is some slip built in. <IMG SRC="smilies/mad.gif" border="0">

ADD (Automatic Differential Disconnect) and auto hubs are two different things. They work completely different.

Aw, my bad.
i knew that add was auto diff disconect, but i thought they meant auto hubs.
I got it know though!! <IMG SRC="smilies/beer.gif" border="0">

if you need any parts associated with a nonadd system i have the front diff and everything(except manual hubs) on the truck that your tranny came out of. i have no use for that stuff whatsoever and you are welcome to it if you need/want anything...toyfamily may have parts to the wiring harness on the cab off that truck that he may not need(not running the auto/v6 etc) if some of the sensors are there you need?? <IMG SRC="smilies/wink.gif" border="0"> <IMG SRC="smilies/wink.gif" border="0"> lemme know...
