Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by Has transmission shifting smooth again. First time I've used this product, but I am satisfied. August 16, 2016
Rated 4 out of 5 by Resolved transmission issues Had sticky solenoid valve, causing jerky shifting, SeaFoam seemed to loosen valve. November 5, 2015
Rated 5 out of 5 by Professional Product, Professional Results Trust me, I'm a professional... ;-) Seriously though, Trans-Tune is a great product. Use as indicated on the can. This is NOT a "fix-it" or leak-seal product. This is a flushing agent, to be used as part of a regular fluid maintenance service. Don't buy this thinking it'll "fix" shifting or power steering problems. June 3, 2015
Rated 5 out of 5 by good quality product. This is the best choice to extend my transmission's life. August 16, 2013
