Sounds like a good idea with the wax or soft plastic to mold and measure the gap. I have to check into that also shocky! I will definitely look into ebay as JimmysotherFORD stated, good info thanks. I did not think of the torque converter/flexplate as fastforward7 thought about. I will need to check on that and in the mean time keep looking for a replacement.
What is involved to check on the torque converter. I am not a mechanic but I am hands on and can use common sense some times.
Thanks a lot for all the good information. If anyone knows of an engine available or a reputable source to get one please let me know.
I would like to get another motor to replace this one and get it rebuilt for the next project.
On the 4R70W there's an inspection panel on the front bottom of the bellhousing. The 4EOD is probably similar. Just two bolts hold it on. Remove that and you'll see the flexplate. There are 4 studs on the toque converter that attach it to the flexplate. Rotate the engine by hand using a socket (18mm I believe) on the crankshaft pulley. Make sure the nut is tight on each stud.
If this does turn out to be the problem you'll probably need to replace your flexplate because the holes in it that the studs pass through will usually have rounded out from being loose.
