RE: [Chrysler300] F transmission mount donut

["'John Grady' jkg@xxxxxxxxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Exactly right, Richard ! It raises it up maybe ½” or a little less  if in there. (mine was flattened out) But with it all apart, seeing how it works,  tail of trans can move off center side to side too,  if rubber not there ; weight of trans seems to compress spring about ½’ too . (good to know that) Maybe other F’s  I had seen  in past was already missing this piece? Why I never noticed that. But I have noticed that center bolt hanging down. Would transmit vibration to frame and cause a rattle? And allow U joint to decenter , side to side .

 

Perhaps Gary made it? I do not have his catalog handy..

Hi John,

 

I too am interested in this. Now that you have mentioned it, I think I am missing the “donut" from my G. At idle, the exhaust is hitting the frame. I had assumed the motor mount(s) had gone bad, but the brake torque test made them look good. Next, the engine and trans seem to be sitting in car square, so the trans mount is OK. I got underneath the car and the center bolt seemed to be extended below the crossmember. I could lift the transmission up towards the floorboard, perhaps 1/2”, clearly something is missing, or the spring has permanently compressed to an undesirable height. I am now thinking I am missing the “donut” you mentioned. 

 

As I look in my ’61 parts book, this appears to be part number 2122280 “stop”. 

 

I am assuming the F and G are the same. Any chance this is what you are referring to? 

 

Best regards,

 

Richard Osborne

Anybody know if this is made? Or source? 

 

I have the rubber block type mounts, go on top of this, but found this rubber “wheeled Donut’ kind of thing , about 1.5” diameter at top of spring in lower trans mount was rotted out . Did not know it was there even , until today. 

 

Related, A518 fits in an F floor !! (A blocks / early / late hemi only)
