Jackbird1812

My mt was recently dropped and was stuck in first gear I've opened the transmission and found that the aluminium that holds the metal dowel pin in place has broken (photo and video attached) is there anyway I'd be able to get this welded if not I'd have to replace the casing but it looks like I'd have to replace the whole bottom half of the engine which is a lot of work for a dowel pin anyone have any ideas...
