My Navajo Lost All forward Gears without Notice

[Bruces expo]

Yes , I put my 4.0 plate against the 2.9 trans and it lines up , Except the very bottom

 

[Dano!]

My opinion would me if it holds up in a B2 than it will hold up with the 4.0 because your still giving that bell housing all the support it was designed to take by using all six holes it came with.

I personally have not done this kind of swap, but if the insides of that tranny are the same it will get you where you need to go. You don't have very many options because of funding. Just go easy on it when you get it all installed.

Well thanks dano , Was about to load some pics of the two Side by side , but my Usb ports on my laptop just stopped responding and picking up my camera or my usb mouse , Still need to figure out the linkage issue , Maybe I can find a floor shifter with PRNDd21 !

 

[Dano!]

Good luck Bruce keep us updated.

 

[Dano!]

Will the B2 bell housing cover the 4.0 flywheel? Have you test fitted it yet?

 

[Bruces expo]

I have not test fitted the trans to the motor , But when I lined up the Spacer plate for starter it lined up minus the bolt locations

 

[Bruces expo]

Well my Laptop Started to Work with me again , Here are some pics of the 2 Trans ! ,

Both side by side , BII On Right , 91-94 A4ld On left With Torque Converter

BII With No Torque converter

91-94 A4ld With Torque converter

See the Difference !

 

[Bruces expo]

Well figured I'll add Some pics

Transfer Case removed

Transmission Support Removed

Pass Side With everything but bolts Undone

Driver side with Everything removed but bolts

Torque Converter Nut removal

Motor support on Bottom

Motor support on Top !

Transmission Removed , Lines Covered , Wiring Out of the way

Here are some pics along my way so far

 

[rickybobby]

I have been without those 2 bolts for almost a year, the threads came out with the bolts. I have had no issues without them, and i abuse the crap out of my explorer

 

[Bruces expo]

Thanks for the info Rickybobby , I think I'm going to try and bolt it up and see what happens , I would like to get a Auto Floor Shifter to Install Since the Shift Linkage is different between the two trans

 

[rickybobby]

the linkage should be bolt on, if not you can pull the pan and swap the internal parts too

 

[rickybobby]

On my 86 ranger (should be an exact match for your new trans) i was able to remove the entire linkage to replace the seal on the input shaft. I got it down to just a stud and shaft sticking out of the case. The old trans should be the same way, so the only potential problem i see if im right is if the angle on the linkage is wrong

 

[Bruces expo]

I Want to Avoid any and all Removal of parts from this trans , I drained and cleaned the pan , was kind of dirty , but Mine was allot worse , I would rather do whats easiest , I tried to take the Linkages apart and swap them , But the Actual linkage Does not remove Like the Kick down Linkage

 

[Bruces expo]

Well I went to Pull a Part South Atlanta , And found that All 3 Bronco II's had 5 Speeds in them , So No luck on a Auto floor Shifter , Found a Trans Fluid cooler with a Line and clamps, Grabbed a Handful of fuses and bulbs , Walked out for only $15 ! , Will be going back with more time and money and Will get More random stuff !!

Now it looks Like I will be Changing the Linkages between the 2 Trans That I have to Make the BII Trans Work , Wish Me luck all !

 

[wood1]

Good luck buddy. I'm confident in your engineering abilities!

 

[Bruces expo]

Thanks man , Not really looking forward to doing the Linkage change but It has to be Done ! , I bought 2 Gals of fluid , still need to buy the filter and pan gasket , but might go get that tomorrow

 

[wood1]

I wouldn't worry about the bottom bolts issue. Just my opinion mind you...

Make sure you flush out your cooler and lines.

 

[Bruces expo]

I have flushed all but the 2 main lines from trans to coolers , I flushed the Radiator cooler , stock front cooler , and will be doing both lines before the trans goes in , The second cooler I bought is flushed as well now

 

[wood1]

Two coolers in series? That's what I decided on, that and an external filter. The inlet and outlet nipples have to be either pointing down or to the side on the coolers. If you mount it so they are pointing upwards you could have an airlock situation. So I have read anyway.

 

[Bruces expo]

Yes 2 Coolers in Series , I have yet to find a Local place to buy the External filter , But I do plan On finding one ! , The fluid coolers are going to be beside each other behind the Grille area , where the Stock 1 Cooler is originally located , I Wanted to get a Temp gauge for it as well as a Drain Plug , But have been low on funds and need to Sale some stuff locally
