C5 or Torque Converter Bad?

When I installed my torque converter, I set it on the input shaft of my C5 auto, and rotated it at least twice until it set in place. But when I moved the trans into position, it was just resting on the alignment dowels when I saw the bolts for the torque converter poke though the flywheel. This is when I tighened the converter to the flywheel, THEN I finished bolting the bellhousing to the back of the engine.

Now I'm spilling fluid after adding 5 quarts of trans fluid, the trans won't engage in any gear, the engine won't even change its idle. And the parking pawl isn't catching so, every position is still neutral.

Is my transmission bad, or did I screw up the installation of the torque converter? I only ran the engine a total of about 2 minutes by starting it a few times for like 30 seconds at a time.

Any ideas what to look for when I pull it apart this weekend?? Thanks guys.

It sounds like you have a couple of things going on. It sounds like it is not picking up the fluid. That could be any number of things, including a screwed up pump or convertor or possibly a loose valve body. The problem with the park could be in the linkage inside the trans. The convertor should not have been bolted up until the bellhousing was tightened to the engine. It is possible that the convertor was pulled out of the pump when it was tightened up, if there was a large enough gap between the engine and trans.

Thanks for the response, I re-installed the converter the right way this weekend. You were right, the pumps shaft wasn't even in its spline.

After filling the converter with more fluid and installing the transmission again, I filled the case with fluid again and now I have the parking lock engaging. So at least the trans is locking into place. But still no engagement.

I'm going to look into how to check my valve body in the KB and read up on how hard it is. I realize changing the pump means pulling the trans yet again, but if I can check the valve body somehow with the trans attached to the engine, I'd rather find a way to test it or change it before pulling the trans out again.

Thanks again for the advice.
