Can I pull the engine and transmission out as one unit ? My 53 block has finally cracked so bad I am leaking a gallon of antifreeze every 100 miles . Also my fifth gear repair on the nv4500 has 56000 miles on it and it just blew up again I’m quite surprised it lasted as long as it did anyway i found another block that’s not a 53 so I’d like pull them out together if I can and replace the fifth gear and the synchros and swap the engine blocks
