Yesterday, I installed the Corvette and Sonnax 4th gear servos, longer pin and replaced the trans filter.

Requisite pics-

Stock servo assembly compared to upgraded goodies. I had probably 1/4" of travel in the servo when it should be around 1/16"-1/8". With the longer pin, I'm right around 1/16". I'll probably get back under it to try to measure for a hard figure.

Magnet looked 'okay'. I mean, I've pulled pans with much more material on the magnet. But, I'm sure this isn't the first pan removal/cleaning, either. The gasket I took off was a FARPAK.

Pretty normal for that magnet. How many miles on the trans?

Not sure. I've owned it since 147K and it currently has 200K. I don't suspect the trans has ever been replaced, but I'm sure it's been serviced before. So, this magnet is at least 57K miles of wear.

Yup. I had trouble on the first one, planning ahead to use the sawzall.. sure enough took me about 20 seconds to put that blade on the damn things. Same thing on the driver side, and I don’t have any rust to speak of, these parts just take heavy corrosion.

Im talking about the rears bushings. Not the links. One of the bolts that holds the bracket for the bushings is stripped. Cant cut anything
