Leon’s Transmission would like to invite you to help us celebrate the grand reopening of our Simi Valley location!

Leon’s has been the go-to place for transmission repair in Southern California for over 60 years. With 9 locations across the Southland, there is always a Leon’s close by.

Our Simi Valley location has been independently owned and operated by Dan LaFleur for the past 45 years. With his retirement, Leon’s Transmission Service, Inc., a family owned and operated corporation, will take over operations starting November 1st, 2020. After a few building improvements, equipment upgrades and a whole management staff, our Simi Valley location will be better than ever and be ready to serve the local community like never before.

Join us on Saturday, November 7th as we celebrate this milestone with a free BBQ for all members of the Simi Valley community. Enjoy hot dogs and soda plus free Leon’s swag! The event will run from 11am – 4pm. We have ample parking on site plus parking across the street at the bowling alley.

Make sure to bring your mask!
Social distancing practices will be enforced for the safety of all participants.
