any change? ugh, this is no bueno having a nice ass runner like yours just sitting there.

 

Nothing yet. Kinda hard to work on it after I broke my collarbone. Today I'm gonna unplug the transmission and see if I can get it to move by shifting through the gears manually. I figure if that works, I have narrowed it down to an electronic issue. If it doesn't move, I'm no worse off. Thanks for shootin out positive thoughts. I wanna get this sucker goin too.

So I tried that and still no movement. At this point, based on the fact that it moved a bit before going kaput, I'm gonna guess solenoids. I am wagering that the guy that had it before me never changed the filter either. I'll replace the solenoids and the filter and see what happens. Gotta wait for the cash to come in.... so it'll be a bit. I will keep everyone updated.

 

Okay. For some reason I think I screwed up the overdrive wiring. These are pics of the schematics:
97 4runner:




95 4runner:




Here is what I connected: 95 first connected to 97

IH1(21)-H(7) OD1 to ecu
IH1(4)-H(6) OD2 main switch.

If anyone can remember how they wired this, can you look at the above schematics and see if I got this right. Thank you.

 

Okey. Good news. Transmission works great. Bad news....I'm a moron. Low transmission fluid cause the whole issue with that.

More bad news.... I went out and started the truck again, and again, no movement from anything. I decided "Okay, since you have a t-case leak, pull the cases down and fix that. Take a break from the trans and do something simpleish." I seperated the cases from the transmission and look up and see a lot of red ATF coming out of the front of the transfer case. I then looked at the rear seal for the transmission and see a lot of red ATF coming from that also. The rear seal is ripped so all my ATF goes into the t-case and I lose my hydraulic power to make the transmission work. CRAP!!!! "Hello Marlin Crawler, I'd like to place an order."

 

well that is good news! ah well sorta... At least you most likely found the culprit!

 

So after mending from the broken collerbone(mostly), I put in the new rear trans seal and also resealed the cases. I refilled the trans with fluid and the transmission and both cases spin nicely. I gave it some gas to see if it would move once I put it in gear, but nothing. When I put the cases in gear, they stop spinning freely, I'm guessing because they are waiting for power from the trans to continue turning them. There is pressure holding the cases in gear so I'm just wondering if I need to give it more gas. I had it up to about 2800 rpm and nothing. Any ideas?

Just curious, would the shift detent ball and spring have anything to do with this? I don't think that I tore it down far enough to get to those parts unless they can fall out of the top of the shifter holes.

 

Okay, after fiddling with it some more today, my opinion and my question have changed. I don't believe that the cases are locking up. I think that the transmission is not able to build up enough hydraulic pressure to spin everything. Here is why I believe that. I had the shifters out and turned the truck on. With the cases in neutral, they spun quickly for about 3 seconds then stopped spinning. I went through each gear on the transmission and the saame thing would happen, the t-case gears would spin briefly and then stop. I was only able to go through the transmission gears one time before the transfer case gears would not spin at all.

Now for the questions: if I installed my external trans cooler and ran the hoses backwards, would it cause the above to happen. If that is not the case, what could cause this situation to happen. The transmission fluid is full. I verified that yesterday.

A small fyi...the transmission pan is dented in the middle and raised up about 3/4- 1 inch. I don't know if this would affect the fluid pickup but thought I would mention it anyway.

 

Back to the top with more info/questions:

I drained and pulled my pan and removed my transmission filter. The transmission filter that I pulled has a place for two (2) gaskets. I looked up the transmission filter that is supposed to go with my transmission. It looks exactly the same, except it has a different bolt pattern and shows a place for three(3) gaskets. This is the one that is supposed to go on the transmission: http://www.transmissionpartsusa.com/...40%2D00094920H

Would that extra hole that needs the gasket cause the transmission to not pick up and push fluid throughout the transmission?

 

I checked the shift linkage, and that is correct, and also cleaned out the filter. I am still not getting any fluid pressure through the trans cooler lines. I am now thinking that the trans pump may have gone bad. How difficult is it for the home mechanic to change out the pump. I know I also need a new o-ring for the pump. Is there a gear behind the pump that may have broken? Thanks

 

So I pulled the pump out of the transmission and this is what I found:

Broken pump gear. Now to find a new one. Any ideas?

 

looks nasty... id say get one from a salvage yard to replace it?

 

looks like its time to get a full rebuild, or get a good used unit. Its hard to verify your wiring if the transmission is kaput period. Oh fyi, usually with these transmissions the trasnfercase goes out before the transmission or the overdrive falls apart. It may cost more but I think a full rebuild would be a better option if you are keeping this rig for a long time.

 

nevermind. I found the info.
