Engine install problem

I have rebuilt my 4.0L in my 2000 tj and have bolted on the flywheel and torque converter but when I droped the engine in, the input shaft on the transmission went into the torque converter and seems to spline up nicely and I can turn the engine fine. But when I tighten down the transmission bolts going to the engine, the crank will not turn at all. Is there any certain way to get the input shaft into the torque converter properly or could it just be that it is not tightening on strait? has anyone else had this problem?

You have to install the torque convertor in the transmission prior to installing the engine and makes sure it's fully seated in the front pump.
If I understand you correctly you bolted the torque convertor to the flywheel and then installed the engine? If so there's a Good chance you damaged the front pump, front pump seal and possibly torque convertor.

this is what i thought, i am hopeful that nothing is broken. I did not tighten the bolts very much at all since they were tight and i did not turn the engine either, i just checked to see if my jerry bar was stiff and it was so i didnt give it any force to try and turn the engine so i dont think anything is damaged but I have my fingers crossed

now on the 32rh auto tranny in the 2000 tj, is there two or three drops when you put the torque converter on?

Thanks for the help

Examine the torque convertor snout and seal very closely for damage replace if needed. Line up the torque convertor and rotate its should clunk/drop in twice. Hope nothings broken.
