Well I got in there and it was not good, but not as bad as it could’ve been.
My torque converter went bad. It had been going for awhile and was planning on replacing it and evidently I waited a little too long and probably drove the truck a little too hard. The torque converter expanded, putting pressure on the main bearing, which in turn chewed up the end of the crankshaft and the main bearing. Had to pull the engine, replace the crankshaft and main bearings. Finally got an opportunity to replace my 44 year old engine mounts, the last bit of original rubber on the truck. But I wasn’t particularly enthused about it.
The good news is that everything else inside the engine looked brand spanking new.
If your torque converter is kicking the bucket, stop driving and replace it. I had several people reassure me I was ok driving around on a faltering torque converter, and that might be true to an extent, but it certainly wasn’t worth it for me.
