How long will it take to change rear main ceal and how much would it cost? on 2001 Suzuki Grand Vitara

Oil was leaking from the rear main seal and need to know the time and cost to fix it

Asked by for the 2001 Suzuki Grand Vitara
Write back, tell us if it's manual troans or automatic, and if it's 4WD or not. To do this job you generally pull out the transmission to access the seal, so I'd have to know about those features.
It is automatic and it is not 4x4
