What a difference a trans mount makes!

[Deleted member 8987]

My MK2 has first gear "judder", sometime badly.

I discovered early on the snubber (top of bell to scuttle) was WAY over tight, and the peg that hangs down off the trans had a big piece of wire through it (for shipping only, supposedly).

Well, ordered the two rubber bits and a new spring, pulled the crossmember out and cleaned 1/2" thick crud off it.
The rubber was shreds.

Installed the new bits (after cleaning up all 8 bolts and anti-seizing them) and took 'er out for a test drive.

Cold was always the worst for the "judder", and if there is any whilst cold, it is so far less than it was warm, I am not certain I even feel it.

If it don't monsoon tomorrow, I'll give it a blast to St. Arbucks and back.

Your description of the mount R&R conjured up memories of that thing.
How are the motor mounts?

you are correct, the piece of wire through the Peg, is/was for servicing purposes, as in "removal of the crossmember", then it needs to be removed for the peg to travel up and down. A Cotter Pin instead of wire would have been the preferred "piece of wire".

A Service Bulletin was issued in 1964 for the 1963 S type; it looks like Service depts. left the cotter pin in place after replacing the rubber in the crossmember or the transmission causing a "thrashing" of the transmission during driving.

Motor mounts are fine...checked them earlier.

Upon closer inspection, the "piece of wire" turns out to be a straightened out cotter key.

BIG cotter key.

there you go. was there a large washer under the large cotter pin too? both the cotter pin and the washer need to be removed per the SB. The transmission needs to have free up and down travel according to engine and driveshaft torquing. The rubber or spring are there to help the tranny go back to "zero" or "level" position once the cotter pin is removed.

my S type still had the cotter pin and washer in place when I bought it!

No washer.
Should have been one, but, you gotta remember, I am un-doing 30+ years of "gas-station maintenance".

here's how mine looked before removing the cotter pin and washer...

here's part of the Service Bulletin...

here's the actual Service Bulletin, I understand there was a similar one for the MK-II...
