Default When to Shim a NEW Torque Convertor....

If the gap is between 1/8in to 1/4in is that good to go... and over 1/4in then shim it a little bit... thanks..

I'd shim it to a 1/8". More than that and the converter will probably get pulled out of the tranny pump some and destroy it.

Just the opposite of what was posted above,a larger gap means the torque convertor is further into the tranny,BUT the 1/8" is correct/better.

If the gap is larger than 1/8 then when you go to bolt the converter to the flexplate it is going to pull the converter further out of the tranny than it would with a smaller gap.

Hopefully this is a relevant question y'all can help me with:

My new torque converter had a 1/4" gap between the flexplate and the mounting pads of the converter. I put in 1/4" spacers, but they really had to be forced between the flexplate and the mounting pads of the converter, meaning it was probably forcing the converter into the pump. Should I go back and space it to about 1/8"?

Yes, it should be shimmed to 1/8" gap. I would go back in there with new shims.

I'm totally new to autos, is that why my trans sounds like it's clunking around sitting at idle with no load? Because my converter is sitting too deep in the pump?

Yes, you can cause pump damage!

Most likely. If the pump is broken, there is a chance that metal bits have gone into the converter as well. The only way is to pull the tranny and open it up and inspect the pump. If it's broken and metal bits are in there the only way to check the converter would be to have someone cut it open. The cost for something like this can add up pretty quickly.

OP don't drive your car another foot..

Hopefully you didn't do any damage, but from my research it looks like you can do damage fairly easy with an improperly installed converter..

Get under your car and investigate

Hey guys, I know this isn't my thread, but thanks for the replies. I went home immediately and replaced the spacers I had in there with some washers of the appropriate thickness and of course the noise disappeared.

However, I noticed that the intense vibrations had managed to begin backing out the flexplate to crank bolts! The flexplate is loose! So damnit, I have to go pull my tranny to tighten those bolts... Glad I found it when I did! Thanks, guys!

Glad to hear that you've everything sorted out. Hopefully there wasn't any pump damage. When going in to re-tighten the flexplate bolts I would also put some loctite on them.
