Engine/tranny bound while installing engine.
I had taken my engine out to do the manifolds (some of you were a huge help while doing the bolts) and tonight I started putting it in. I got the engine lined up to the tranny and bolted; however, when I started to tighten the bolts I noticed it was getting very tight, and the engine would not turn over, even with a breaker bar on the crank. I had taken off the flexplate to see if the rear main was leaking while the engine was out, which it was not. I left the plate off for about 2 weeks until today when I put it on. When I put the adapter on it was a little snug, but it came off easy so I did not feel the need to slam it on as hard as I could. To put the adapter on, I used a block and gave it a few good whacks with a 4 pounder. I then bolted it together and torques it. Now, I am thinking it is not all the way on, because if I let the bolts in the bell housing off slightly. The engine and torque converter will spin over. Between the rear main seal and adapter, is about a 1/8" gap. I don't remember exactly but I think I remember plenty of room to put a screwdriver behind it to pop it off. Do you guys think that it could not be on correctly? Or maybe something else is bound up? Any help is appreciated. Thanks!

So you bolted the converter to the engine then slid the tranny up to it? How can you get the front pump lined up/engaged? I always put the converter into the tranny first and make sure it lines up with the pump and drops in all the way, then slide it up to the engine and bolt the converter onto the flex plate. I think you are jammed against the front pump and not engaged with it so the converter won't slide into the tranny all the way.

I completely agree with this. Stop what you're doing, remove the torque converter from the flex plate and put it on the transmission. Turn it while sliding on and you should hear and feel three "clicks." The torque converter should move in a little each time it clicks. There should be a gap between the flex plate and converter when the engine is bolted up to the transmission. If the converter is tight against the flex plate, something isn't right and you're on track to destroy the transmission's front pump.

what the guys above said. if you do not seat the converter into the trans front pump properly, it will not "lock in" and when you try to bolt it up the trans will not fit flush to the block. then when you crank down on the bolts, you force the converter into the front pump. this usually results in a cracked pump housing and ruined converter.
