Vacuum Modualtor Push Rod

[nickoluswiebel]

Hello, I recently replaced my vacuum modulator in my 1994 Geo Tracker with the 3spd auto trans 3L30 (th180) . Apparently the push rod fell out and I didn’t notice and now I need a replacement. It looks to be a roll pin. Anybody know where I can find a replacement or what size pin it is? Thanks in advance and I hope you can help.

3speed modulator on rear for 3L30,  and the right color code , correct?  the color matches weight of car. (lots there are just for this  1 part) purple is corrct for this 2door car.

well,  Autozoned does not sell  those, nor suzuki and nor GM now.
there are only 3 places. (if at all)

1: wreckering yards, but they'd never take down a good box just for you.  car-part.com (example1)

2: Ebay. or googling by correct P/N. (low demand and so few buyers now, makes this hard to find here. All I see  is this....

3: transmission parts houses sell parts for most transmissions.  https://www.transmissionpartsusa.com/TH1..._s/652.htm

the transmission is TH180 box, by GM, many were made in their  French factory there,  and used even on all very old now, USPS mail trucks. 2door right and drive.  1973 first.
the 3L30 is just mod, by GM to make it fit on a 4wd transfer case. that adapter. do you have 4wd box?

here is the parts blow up, by GM.

see part 160,  in that serial chain  of parts.  you lost part 163 and or 164.

suzuki shows part  24 lost?

ID24: is suzuki p/n   (Suzuki actual, shows discontinued on all these boxes) GM same.  as you can see part 26 comes with the new MOD 25
