2000 Ford Ranger 2.5l torque converter
I’m in the middle of doing a overhaul on my motor. It’s been the the machine shop, grounded crank and bored over installed new bearings and pistons and rings, the whole 9 yards. We put the torque converter into the transmission and seated it properly and was trying to lower the motor and slide it into the transmission. In the process the torque converter slipped out because of the angle the motor had to be at to clear the oil pan of the subframe and reach the shaft of the torque converter. I didn’t realize this until I started to bolt the torque converter up and tried to turn the motor to reach the next bolt and it wouldn’t budge. Now I need to either pull the transmission back and reseat it or pull the motor again. I need some kind of ideas of the best way to go about it since I have no transmission jack and if I pull the motor and try to realign it that way I’ll risk unseating the torque converter again and having to do the process again. Any thoughts?
Welcome to the forum
Hopefully no damage to the front pump in transmission has occurred.
If engine is flush to bell housing then damage has happened
Torque converter should not touch flex plate after engine and trans are bolted together.
You would need to slide it forward 1/8-1/4" to bolt it to flex plate and it would spin easily to line up the holes to bolt it in place.
Unbolt torque converter, see if it slide back and you can spin it
If not then transmission will need to be rebuilt, full tear down to replace front pump
What happens
On the outer case of torque converter's shaft are two slots, they side into the trans and align with tabs on the front pump(main pump) this is why you spin and push in on torque converter when installing it, to align the front pump slots and tabs.
If you install the engine without slots and tabs aligned then when you tighten up the bolts you force torque converter back into front pump and it breaks.
Did that on my first automatic install, expensive lesson
Front pump provides ALL the fluid pressure in the transmission, so no front pump = no go, in any gear

Not a little issue, if it happens to you
Like forgetting to torque down a head bolt or bearing cap, just a little thing...but with BIG consequences.
School can be expensive, this is one of those "lessons" you never forget, mine happened 40 years ago, I still try to pass along that lesson to others
The fact torque converter/flexplate is not turning means either the engine is seized up or transmission is, front pump has been pushed back and has locked up.
You could force it and it WILL turn once broken pieces move out of the way.
You could try loosening the bellhousing and try to re-seat the torque converter, but from your description the damage is done.
No, no way I know of to test if its damaged, if you loosen bellhousing and torque converter can be easily turned and then be easily re-seated, then "maybe" pump will work, but for how long???
