### ⭐⭐⭐⭐⭐ Review
*by J***E on 13 September 2020*

I started noticing oil droplets on my driveway and the transmission appeared wet in oil but it was not red so I knew it was engine oil. Sure enough, the rear seal had a small crack. I used a jack to support the transmission while a buddy removed the old seal and installed the new one. This seal is super easy to install with the tool it includes, slides great and it definitely seals great. I've had the seal for 7 months now I believe, and it is working perfectly! No oil leaks!
