I have bolted my powerglide to a 400 small block engine. when the bolts are tight the torque converter seems to be rubbing the trasmission case. I have seen a item that appears to be a shim sold on Speedway motors has anyone used these shims before? I saw them advertised and was not sure if they are meant to offset the torque converter when you have this problem.

Where on the case does it appear to be rubbing?? Got a part # for those spacers so we know exactly what you are referring to??

I should have added the description it is refered to as a flex plate spacer. part number 91048367. The description says it is used to give more room between starter and flexplate but this would also move the torque converter farther to the rear also? It appears the fins on the converter that show the turbine blade pitch is rubbing on the case. I thought maybe one of these spacers would give the needed clearance?


Thanks

You mention "fins" on the converter, meaning it's an air cooler Glide, or at least the converter is. Are you sure the converter is clocked right with the front pump drive gears? The "shims" sound like starter motor shims to me (?). Stock, the 400 takes a 14" diamter/168 tooth flexplate. You do have the correct starter for the flexplate? I can't see the "fins" causing interference, but what part of the case is it hitting? Butch/junior stocker.

Perhaps the "fins" are bent and that's causing the problem.

the fins I am referencing are the fins on the torque converter. This also used to visually give a person an idea of the turbine blade pitch in the converter. It appears these "fins" are touching the bell housing case. You are correct the shim speedway lists are to move the flex plate back to give more clearance for the starter but this would also move my torque converter back also.
And I am wanting some feedback from someone that hast tried this.

Torque converters in a power glide trans do not have fins on them , unless it is an air cooled torque converter as mentioned.

If you move the converter back , I would think the rubbing would increase.

Shimming the flex plate back is incorrect , un-needed if the parts are correct

You are right that the Speedway shim you are referring to(goes on the crank before the flexplate does) is going to move you in the wrong direction. If I understand you correctly, you are saying the internal fins anchor point "bumps" on the surface of the converter are rubbing the trans case inside the bellhousing?? Somewhere near the pump or near the engine face??

Where did the converter come from?? Brand?? What diameter/stall??

Are you sure it is a glide converter??

I bet its either damaged or is the wrong converter, could the flex plate be on backward or does the flex plate work either way?

[junior stocker]

OK, so it's the "creases" for the internal tubine fins. Never heard of that before either. Maybe get a known working converter and swap it in just to see. Has to be the wrong converter, or something is wrong with the setup. Butch/junior stocker.

Something must be wrong with the converter,it should be able to spin freely with the tranny bolted to the engine and the converter not connected to the flexplate with no rubbing.
