You must remove the transmission are engine to replace the rear main seal.
That engine has a solid round one piece rear main seal that slides over the rear of the crankshaft. You will either have to remove the engine are transmission to be able to replace the rear seal. No other way to do it. ( BIG JOB ) and a good paying job.
You will have to replace the rear main seal. This will require that the transmission be removed.

No you can access the rear main seal by removing the Transmission, flywheel etc
Front seal: remove engine or transmission and replace the seal. Rear seal, remove the drive shaft to replace the seal. Unfortunately, you typically only have problems with the front seal.
Pull the engine.
You can either pull the engine out or remove the transmission and flywheel to install the rear seal. It slides over the back of the CRANKSHAFT on the back of the engine. Must remove 1 or the other to replace seal.
You will need to remove the transmission.
You have to start by pulling out the transmission, this will give you access to the rear cover of the engine, and the rear crankshaft oil seal. You have to remove the rear engine cover once exposed, then you can pop out the old seal and press in the new one! And re-install transmission.
