What are the 2 differences between a transmission designed for transvers front wheel drive vehicle compared to a rear wheel drive front engine vehicle?

Transmissions for transverse front-wheel-drive vehicles are typically more compact and integrated with the engine, allowing for a shorter overall length, which is ideal for space efficiency in smaller vehicles. In contrast, rear-wheel-drive transmissions are designed to accommodate a longer driveshaft and may incorporate a more complex layout to handle power distribution to the rear axle. Additionally, transverse transmissions often use a simpler differential design, while rear-wheel-drive systems may require more robust components for handling higher torque loads.
