Does the engine need to be removed to take the trans out?

Hello Folks,

I have an 2015 RZR1000 that’s had several problems from day one. I believe the dealership is responsible for most of the problems. The transmission has been pulled out of the vehicle 3 times. The RZR just started leaking a large amount of engine oil. It appears the oil is coming from between the engine and transmission. The source looks like it begins at the bottom of the head. I have zero engine or tranny mods. The car is bone stock. I was originally told by the dealer that the engine gets removed with the transmission. Now that there is an engine oil leak they are denying ever touching the engine. Does anyone know if the engine gets removed/loosened when the transmission is taken out of the vehicle? Any ideas on the oil leak?
