Hi,
I have a 1964 buick ST 300 Trans. I am rebuilding I seem to have lost one of the reverse piston springs :clonk: it is green is there any other spring from a similar trans. that would work,? anyone out there know where I could find one?:confused:
Thanks
Tom
 
It is a reverse piston return spring, GM part no 3789061. GM once sold them in boxes of 17, enough to do one unit.

Used on:
64-68 ST-300
64-66 Olds Jetaway
?? Pontiac version of the ST-300 (don't have many parts books for Pontiacs)
62-73 Chevy Powerglide and Torqdrive

There's a couple of current auctions on eBay for incomplete boxes of springs. Looks like others needed just a couple, then put the rest on a shelf decades ago. Just Google GM 3789061 for even more leads. Luckily the item had high usage in Chevies.
