installing tranny....need help!
 

After pulling my tranny down and installing my new Edge converter, I'm having trouble getting the tranny to mount back up to the engine.
I'm doing this project on the ground, which makes it much harder already.
I can get it within an inch of the engine but I just can't seem to snug it up the rest of the way. All the bolt holes seems to be inline so far. I also made sure the converter was seated properly against the pump.
Why won't it go together

Ok, I am going to list some of the things that I have had issues with before, see if maybe any of these could be you.

Even if you did not have the TC all the way seated to the pump, the transmission would more then likely come close to bolting to the motor, but the TC would be pinched between the flywheel and transmission. Are the TC studs properly going thru the flex plate? My new Ebay flex plate this year had one hole that needed a little "massaging" to get the TC studs to all come thru the flex plate freely. Those few threads catching on that hole held me up.

If your studs are coming thru nicely, then something has to be catching it. But my get is the TC studs are not perfectly fitting your flex plate. Here is another thing I have done while installing my autos. When you have the studs of the TC pushed thru the flex plate, grab one of those studs, and wiggle it clockwise and counter clockwise. It should move freely back and forth and make a nice little "ting" noise on the flex plate. If not, something is binding.

As I say all this, then think about a c-6 I messed with last summer. It may have had bolts that screwed into the TC vs. studs mounted in the TC. If this is the case with you, I am not really sure what it would be. Is the hub on the front of your TC too big to go into the flex plate? Just grasping here now…..

Also, make sure you put that aluminum shield in there between the flex plate and the engine. I have forgotten that a time or two :D

Let us know,

Don't force it (i.e. use the bellhousing bolts to pull it in). Take the trans back down and make sure that you've got the converter fully engaged. You'll have to line up two set of splines plus the pump support to get the converter all the way in. It can be frustrating, but keep working the converter and it should go in.

Lay your two converters side by side and make measurements all all engagement points, internal and external to make sure you've got a correct converter.

Lastly, after you do get it installed, make sure you've got about 1/8" free play between the converter and flexplate to ensure you don't bind the pump or wipe out your engine thrust.

My bad, you've go a C-4. You'll only have on set of splines to engage. I was thinking AOD where you've got the direct shaft too.

Don't forget to check the nose of the convertor where it goes in the back of the crankshaft. Make sure it fits there.

Also, C-4 does have two sets of splines. Front pump and input shaft. AOD had three.
