Sonnax700R4 Governor Gear Kit, GM 4L60 4L60E 700R4 Transmission Kit

My old governor gear was broken on my 700 R4 transmission and it wouldn't shift from first to second gear. The auto parts stores and the GM dealer could not help with the part as it now obsolete. I ordered online, the parts came well packaged, on time and without damage. Drilling the hole and installing the pin was straight forward. Now I'm back on the road, and would recommend.

Great little gear, and fits as expected. Turns out my issue wasn't the gear itself, my governor was just stuck. Just needed a good cleaning. Changed the gear anyway since I was there. Only 4 stars because I had to drill a hole to put the pin through.

It was a little tight fitting the gear in the Governor, a few light taps and it seated fine. Ran a small drill bit through the Governor roll pin opening to drill through the plastic gear to install the roll pin. Drilled 1/2 from one side, 1/2 from other side, went through with no problem, just go slow and drill through plastic gear only, took 5 sec. This replaced my original chewed up Green gear perfectly and fit in the Trans nice and tight against the output shaft gear. Just put it in and let it turn to lock in place. When installing the cover, use a small amount of RTV Sealant on the covers flange and tap in from the sides with a soft mallet.

Part was shipped fast.....and an exact fit for my vehicle.

Perfect oem style

Just what I needed thank you

I'll change my review if I'm able to make it work, but the part didn't come with a hole drilled for the roll pin.

Great product!! Super fast shipping!!!
