I have been replacing the front main seal in my tranny, and durring the process my buddy helping my, took of a little round plate on the drivers side of the tranny thinking is was acess to disconnect the kick down linkage, any way the plate has a big cross on it and is held in with a snap ring and behind that plate there is a semi piston lookin thing with a metal pin in the middle and a spring on it, i can not get it to seat all the way in enough to put the cap and snap ring on, what a mess, if anyone could help it would be great. i figure there some thing i'm net doing.

 

OK if you took out the servo
you my have damaged an O ring that couldbe holding itfrom going in all the way


now the other thing the book says
be sure the servo piston rod is properly engaged in the second coast brake band

 

so I'm looking at a diagram
and it looks like at the end of the rod their is a point then a little edge and a strait surface then it tapers up to its full thickness

looks like the little ridge can catch on the guide surface if its not inserted
perfectly strait
