Finally prepping my 1963 Mk X for a 600 mile trip. It has the BG DG 150 transmission. When accelerating, I feel a shudder and a grinding noise in what I believe is the lock up converter engaging. I have already replaced the transmission mounts, engine mount and the center engine mount on the firewall. Does anyone else with this transmission experience this? Should I worry about it? The transmission does not appear to slip and if I ease on throttle at that point it seems to engage smoother, thanks in advance.
My '63 Mk2 has a DG 250, similar to yours. One of my workshop manuals deals the box. Here’s the diagnostic covering the direct drive. Paul
Hello,
I had the same issue with my DG250 in my S-type.
I swapped out the torq converter as I had a spare.
The direct drive clutch is in the torq converter.
After that all was fine again.

Mine did the same and it was the converter.
This is why she is now a 5 speed.
