My Bronco 2

Grumble.

A4ld is out... Tore down. Nothing's broke. Visually.

edit:
thought about the 8.8 being bad... but the Aussie will let it ratchet so I can't go by the jack one wheel up and spin it method lol I forgot it'd ratchet.

Guess I'll try to find my overdrive issue since the trans is out.

I wanna say cross pin or spider.

So all in all you could have put it in 4wd and that would have told you a story rear quick.

Question is, what could have gone out in the diff? I have heard of ring gear books backing out and coming out and wonder if this happened our shine how you snapped you pinion gear.

Since park was park, and everything else was neutral, motor just reved but it didn't move, we never thought anything put one of the shafts in the trans is broken.

Right? Right? Wrong.... Something in the 8.8 is dead. The day it broke I didn't have help to look if the driveshaft was spinning or not. Stupid move on my part for not checking it before now. But you live and learn.

Ben, you skipped the single most important step in diagnosing an auto trans issue. You didn't check for fluid motion in the trans before ripping it apart. When I get an auto in with a no engagement concern the first thing I do is check fluid level with the engine off and then see what it does when I start it. Most of them don't go down at all.

You can have no visible physical damage inside the trans and still no workie workie if the pump is out. Also, drain the converter really well and look carefully at the splines inside. It is common on the AX4 transmissions for the converter to strip out and you loose all gears because you loose the pump. I haven't heard of it on an A4LD, but that doesn't mean it can't happen.

I'm an idiot. 8.8 is gonna "ratchet" bc of the Aussie.
Forget the 8.8 idea. It should be good.

Double check the converter hub and the pump splines. If you find nothing wrong visually replace the pump.

You really should have checked the fluid pressures before dropping the trans.

also check the fwd case, it could have gotten slipped in to neutral, my ex father-in-laws f150 did that, his girlfriend hit the trans shifter and shifted it in to neutral, he thought the auto in it went bad.

If my tcase is in neutral... Park shouldn't be park.
Plus it's an electric case and it's hard to get it in neutral lol

Nope. I'll do the Frankenstein 5r55/A4LD build

Head over to the explorer forum and find the "A4LD Rebuild Diary" if you haven't already. I was planning on building a stout auto for my explorer, but after blowing two autos in a month (expo and ranger) I'm going stick everything.

Did you ever figure out why she won't move Ben?

 

[4.0B2]

Nah. I've been working to much. In the middle of a huge contract order right now.

 

[Robert_1967]

I wonder if it could be one of the cups on the side of the trans that tighten the bands when they get pressure to them?????

Found this.. Bottom is the one out of the trans. Top one is new. Notice the teeth...
