Default help me diagnos the van issue (FIXED!)

my other thread went in the wrong direction while i was at work i stole my roommates car to get to work today, but that was a one time deal...

let me further discuss the problem

while driving, i lost the transmission power.. the engine still reved just fine. i figured i blew the line and was losing fluid so i killed the motor and pulled over. popped the hood and checked the fluid, its all there. i get back in the van and try to start it. just the starter, not engaging, not turning the motor over.

at this point we pushed it into a parking lot and left it for the night.

after work today i got a truck and towed it home. its now in the garage. and i discussed some possible situation of what happened with my dad. here are the facts:

if the engine is turned over from the front (belt) end, it turns over just fine, and also turns the fly wheel and torqe convertor (there is an access panel to view this)

if the engine is turned over from the front (belt) end, it turns over just fine, but if i hold the flywheel, i can still turn the motor over and it makes a slipping sound

if the engine is turned over from the starter the flywheel and torque convertor spin, but it does not turn the motor over


did i shear the bolts that hold the flywheel to the crank? it doesnt seem like its going to be a huge mechanical problem, but more of a labor issue. is the flywheel turning over when i turn it over by the crank only because of the pressure there? and thats why i am able to hold it even though it appears to be connected.

any help is appreciated... my dad is coming up tomorrow morning to look at it @ 8:30, but is only able to stay until 10:30.. so fixing it does not look good

any MN bc boys up to helping me pull the trans to look if thats whats needed?

My bro says you probably broke the flex-plate. You would still have enough contact that the crank can cause the flex plate to turn, but not vice-versa. He says that the A604 from the vans is prone to that. Fairly basic repair, but hard work and time consuming. You'll have to pull the left suspension, pull the trans mount and front motor mount, which will tet you drop the trans down far enough to pull it out. The hard part is getting everything to line up when you re-install the trans. It'* a weekend job, if you have a helper.

My old Dodge 400 (2.2 w/auto) had the torque converter bolts back out of it, and for some reason would not hold torque at all. My dad finally went ahead and JB welded them in place. Did the van make a noise like a spun bearing?

That van has an A413 trans..... no OD trans with a 4-cyl from Chrysler in the 80'*-early 90'*.
My thoughts are the flexplate too....but it boggles my mind.... I have only seen this happen in the 2.2/2.5 turbo cars with automatics and beefed up power-wise.
