swapping 4.0's, cannot seperate tranny and engine HELP
my girlfriend somehow managed to snap the crankshaft clean off at the face of the motor, so me and a friend are franticly trying to swap a new engine in before we have to leave back for college. we have everything disconnected on the engine, and have even lifted the engine part way clean out, but we cant get the transmission to let loose.
we've taken off the starter, and also taken off the 4 nuts on the torque converter, and have also taken off all 6 transmission bolts, two top, two middle, and two lower. several people we've called have told us something or another about the "inspection" plate i think they said, but my friend, the one who's actually doing the work and knows what he's doing says there just isnt one or its not where it usually is, and cant find it.
we've tried jamming anything and everything between the engine and the tranny to pry it apart, but no luck. we've even shook the holy hell out of the engine once lifted with a cherry picker, no luck. we've tried lifting on different sides of the engine and lifting or pulling on different angles of the tranny, but nothing is working.
what the hell are we missing? we HAVE to finish this tomorrow, or we're screwed. once we get the two separated, it'll take us no more than 3-4 hours to get the new one in and running, we've been working on simply separating the two all day, and we're frustrated and ready to quit.

You remove the inspection plate then unbolt the flywheel from the torque converter (you will need to rotate the flywheel to do this). You can see the inspection plate behind the sump on this page (bottom two pics and plate is sort of semi circular at right angles to lens).
Re: swapping 4.0's, cannot seperate tranny and engine HELP
The pics here show the flywheel. You have to remove the 6 outer bolts that attach it to the torque converter AMC FLYWHEELS the insepction plate covers the lower third of this flywheel. Bear with me as I am in Australia and Ford don't sell rangers he so pics are not exactly at my fingertips.
Re: swapping 4.0's, cannot seperate tranny and engine HELP
my friend says that we've already unbolted the torque converter from the flywheel. he rotated the flywheel all the way around, and there were only 4 bolts.
are there any type of (bear with me, i dont know what they're called) little plug type deals, looks like two metal, cylinder type deals coming out of the back of the engine that set into the tranny to line it up? i looked on the back of our new engine and there's something like that, and we're thinking thats maybe whats holding them together some how
how likely is it that the engine and tranny are just stuck together from having 130,000 miles, and need a severe beating to get apart?
Re: swapping 4.0's, cannot seperate tranny and engine HELP
The only things I can think of:
If you are sure all bolts are removed, you may have to much pressure on it to slide out. You could lower the tranny some, or maybe remove the motor mounts completely so that rather than lifting off of the mounts, it could slide foreward more without strain against it. I'm not sure if there is 2 or 4 guide pins (or plugs) but I wouldn't think this has any effect.
Is the tranny and engine seperating at all???
Re: swapping 4.0's, cannot seperate tranny and engine HELP
we're positive we have all bolts out, and when we pry on it and yank forward with the cherry picker, we can see it very slightly move away from the tranny. it seems like its either still connected in the dead center, because its pulling away on the edges slightly, but we're thinking its sealant holding it together all the way around, and its not busting loose. that, or the dowel pins are corroded, but we sprayed them with penetrant, no luck though
Re: swapping 4.0's, cannot seperate tranny and engine HELP
alright, we got the tranny and engine apart, but we're still having trouble getting the engine to come out. the torque converter is sticking to the flex plate.
we cant get the motor mounts out, the passenger side is quite difficult to get at, beside the point of it being rusted, and we cant even locate the driver side motor mount bolts to remove them.
can we just... like.. hook the chain to my truck and rip the POS out? :(
