Help, bad noises

I have an '84 Bronco II with originally a C5. I put a FSB V8 engine in it and adapted the stock C5.I changed the bellhousing and torque converter. I also changed the valve body to one from a C4. Putting a V8 in was a big job and I did a lot of things a long the way to make it look stock. Bottom line is along with my work and other cars, I spent a long time doing this, on and off.When I finally got ready to start the rebuilt engine, I had only put one nut on the TC, and it wasn't tight. I forgot about this and started the engine. I immediately heard a rapping sound. The engine ran maybe 5 seconds. I started it agin to hear the noise again, maybe 10 -15 seconds. It finally dawned on my what I had done, forgotten the other nuts. I then put the other three nuts on and tightened them up. I started the engine again and the noise was much less, but still there. I put the trans in gear and nothing. I went through all the gears, nothing. When I went to put it back in park, it would not go easily, clicking, then finally dropping into park. So . . sound familiar?? Running it those few seconds with the TC loose messed up the pump?? or?? How about the parking paw clicking and not wanting to go back in? Seems all these things are related . . what have I done?? Thanks

The loose nuts would not have hurt anything. Just check the converter is actaully tight. A normal nut may bottom on the studs and not hold it tight..
As for the other verify the linkage is adjusted correct .

Remove a cooler line at the rad and fire it up.

If fluid gushes out the pump is good.


No gush means the pump is bad.

but . . .

Could I have damaged the pump by leaving the TC loose? Because this was a perfect 58K trans before. The knock is loud.

Cracked flexplate will/can cause knocking noise. Can be very loud sometimes.

You won't be able to see the crack with trans installed.

Flexplate must be removed from crankshaft also.

They usually crack around/near the center pilot hole, or from a bolt hole to a "window" if it's not a solid flex plate. 

Crack can be very hard to see sometimes. A very tiny hairline crack can be almost impossible to spot.

Hold flexplate up and tap with a hammer, it should "ring" nicely. If it makes a "clank" sound it's cracked.

Another way to spot a crack is to pour some solvent on the flex plate, just enough to "wet" it.

Then drop it horizontal on a flat surface (concrete floor) from a few inches up. Watch closely and if cracked the solvent will "spray" from the crack. May have to repeat a few times to see it.

The clicking when puting it in park tells me that either the transfer case is in neutral or the trans output shaft is no longer connected to the transfer case input shaft (dont think that possiable if they are bolted together)

The trans output shaft is spining up with nothing connected, thats why it grinds going into park

It had a 94-inch (2,388 mm) wheelbase and was enclosed in the rear.

Unlike the Bronco, the Bronco II offered four wheel drive as an option.

(all full-sized Broncos were four wheel drive)

you are incorrect Stuart, sorry

March 23 2012, 2:21 PM

"Unlike the Bronco, the Bronco II offered four wheel drive as an option (all full-sized Broncos were four wheel drive) and did not have a removable roof."

This is what wikipedia states.


You are probably correct and if you can change it and supply proof go for it.

It is now changed . .

to reflect the fact that all 84 and 85 BIIs were 4wd.

that sounds good . . .

March 22 2012, 7:09 PM 

I will check that. With the awful sound, that thought never crossed my worried mind happy.gif So hopefully I didn't have the transfer case engaged, now what about the sound assuming nothing is cracked as its all new.

you did tighten the flexplate to crank bolts when you put it together.

I cannot see the loose convetor nuts doing any damage to the pump or the convertor in that short a run time. check the transfer case and hopefuly it's in neutral, put it in gear then load up the trans. Make sure it's full of fluid and see how it goes.

I had a knock coming from the convertor area of my sons 67 stang at idle after we put it together, checked everything-found nothing wrong. After a month of driving it it went away, never did find out what it was.

Hope yours works out as well

Had you done as I suggested earlier you could have focused on a different area.

Checking for fluid flow.
