Pulling AOD

[Broncobill78]

>>>>It's much easier and only a bit more work to drop the t-case first, then the tranny. The B-W 13-56 t-case weighs in about 74 pounds, so you can almost remove it without a jack. But it's bettr to use a tranny jack, since you made need some leverage to separate it from the tranny. I also found it alot easier to remove the exhaust, or at least loosen the y-pipe from the manifolds/headers. You ca nrent a tranny jack for about $35-$40 from most rental stores. JSM84<<<<

74lbs ?!?!What the **** is in it confetti ? An NP205 has to be twice that if not more. 205's are all I've ever changed but I've done close to a dozen of them, I have to confess ignorance as I haven't blown the underside clean yet but I'm guessing at 74lbs it has to be a chain drive w/an aluminum case right ? Jeez, if the chain breaks it must blow the thing right out thru the bottom of the case no ? BTW, my **** is gone so I'm clueless to the shift pattern is it 2hi-N-4hi-4lo starting from the top & what's the deal with those funky dash buttons, are the 4x4 & 4-lo button actually buttons that I'm supposed to push or are they just indicator lights that stick out for some unknown reason ?

Harbor Freight has tranny jacks on sale for $80 until 11/12 so I was looking. I was figuring on a bench rebuild so I'd need to rent the jack twice. I'm going to call the boneyards tomorrow to ck on AOD prices, I'm going to be *really* strapped after I pickup the compressor & air tools so if I can get a dirt cheap AOD that lasts a yr or so I'll be happy enough. You shot down my F150 parts truck idea so I'm spending the $$$ on tools instead until a parts Bronco comes along.

I almost wish I'd left the thing not-running. now I've got a low brake pedal, Rear ABS light, low oil pressure & a smoked tranny. I need more tools.

Yeah, the Borg-Warner 13-56 transfer case is chain-driven, and has a magnesium housing. It's fairly stout, though, even saw use inthe F-350's like my 88. Only major problem I've seen (other than pump failure due to lack of fluid) is the design of the oil pump mount on the side of the case can wear down, which lets the pump spin loose and fail. there's a tech write-up on fixxing that if you check Mesk5's homepage link in the tech articles forum. Ther are two main types of the 13-56, one is manual shift with a lever and the other is elctric or pushbutton shift. The electric shift and AOD are more common, since it's very hard to find the manual shift linkage for the AOD when folks convert from the electric version. Theree's also two sub-types of the manual shift, one has a bolted stud for the shifter linkage and the other has a welded stud. I found this out the hard way from a local salvage yard buddy when trying to help a frined convert from electric to manual. I think he spent about $450 rebuilding the AOD on his Bronco. It may be worth a few dollars to have a tranny shop rebuild yours rather than taking a risk on a salvage yard unit. Good luck, JSM84
