Re: 5.3 to 700R4 help
Usually that means that the converter is not all the way in. Without a shim between the engine and trans, usually there is enough room to spin the converter with it NOT TOUCHING the flexplate at all.
If you haven't done tons of engine swaps you probably aren't used to it. No big deal, except that you have to take the trans back off of the engine, then continue rotating it until the converter drops in deeper. Then bolt it all back together and pull the converter out to the flexplate.
With a shim between your engine and trans you ought to have about the same room that a regular small block has. If your engine has balance weights on the flexplate, they could be rubbing on the bolt flanges of the converter (I have run into that problem using Olds V8 engines) and make it seem too tight.
Either way, you have to unbolt and do it again. If you just tighten it up you will brake the transmission front pump and/or housing.
