Marble sound... POST T5 SWAP - MT
i just swapped a t-5 into my 88 GTA and after the motor/tranny gets warmed up i get a sound of marbles rolling around in a jar. At first i thought it was the throwout bearing cuz i repacked it and didn't buy a new one but its constant, either idling in neutral or driving... clutch in or clutch out.
Car runs hard and shifts fine through all gears with absolutely no grinding or slippage. Any ideas what the issue could be? Not the motor... she's built and purrs like a badass kitty. not to mention it ran fine (aka no marbles!) about a few days before when i had a turbo 400 AT in it.

turns out the issue was my pilot bearing had spun in the crank... so i had to replace it... just thought i'd wrap this up, even though i fixed it a long time ago.
