Sometimes it baffles me how car companies act.
Over at Reddit a mechanic who complained of how a cracked transmission was repaired was fired.
It was a warranty repair and it seems Land Rover was aware of the damage by a co-worker of the mechanic who complained but Land Rover said the repair was acceptable. It was a huge crack in an aluminum transmission case welded back together.

- userbinator 10y agoIf "Land Rover said the repair was acceptable", I'm inclined to agree. In fact, digging a little deeper into that story... http://www.thetruthaboutcars.com/2016/05/cracked-welded-land-rover-transmission-case-comes-close/ http://www.thetruthaboutcars.com/2016/05/cracked-welded-land... ...reveals that it wasn't a problem after all. Search on the Internet and you'll find plenty of others welding various automotive parts, including transmission cases, with no problems. It's a common practice in the industry. A proper weld is as strong as the base metal.
- jacquesm 10y ago> A proper weld is as strong as the base metal. That's true, but proper welding of a gearbox casing is super difficult. You'd have to make sure there was no thermal hardening around the weld and that's really difficult without taking it out of the car, stripping it down and annealing it after the welding and then re-assembling the whole thing again. So even if in theory a good weld is as strong as the base material achieving this 'in situ' is next to impossible, and probably if you did it the right way then it would be un-economical.
