I have a 1947 1/2 ton truck with the floor shift 3 speed transmission, 216 engine. Today I drove the truck and could not get out of 2nd gear without the transmission shaking enough to drastically shake the parking brake lever. Could it be the engine mounts that are bad at the bellhousing?, or do I have a bigger problem? Yeasterday the truck drove fine and early this morning no problem. Kind of just all of a sudden type thing. Thanks for your input. I am going to check the bellhousing engine mounts since I have not changed them since acquiring the truck and the ones on it have sat for over 20 years
