Prolong Super Lubricants 8oz Transmission Treatment

Prolong Transmission Treatment is formulated with Prolong"s AFMT (Anti-Friction Metal Treatment) advanced technology to treat the metal surfaces of both standard (manual) and automatic transmissions. As the transmission fluid or gear oil circulates Prolong Transmission Treatment molecules interact with all of the metal surfaces chemically bonding to create a protective layer that reduces potentially damaging friction and heat. Prolong Transmission Treatment is particularly effective under extreme pressure conditions providing significant protection against one of the most costly automotive repairs. The product promotes smoother manual shifts and helps restore responsiveness in automatic transmissions especially in critical quick-acceleration conditions.
  • Promotes smoother, more responsive shifts.
  • Compatible with all common transmission fluids and gear oils.
  • Formulated with Prolong's AFMT advanced technology.
  • Reduces extreme friction and internal temperatures.


Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Actually works I put this in 2 of my cars that were both exhibiting definite hard shifts intermittently and they weren't getting any better on their own. Added a bottle of this stuff to each and after 150 miles each they drive like new. Wasn't instantaneous but gradually noticed the changes for the better. Only downside is if your transmission fluid is already at the high side of maximum, there is no room to safely add even this brand's relatively smaller 8 ounces without taking some fluid out and of course some cars like mine don't make a drain plug so taking some out can be as labor intensive as a complete fluid flush but saves you from having to get costly transmission repairs at least for a long while!

Rated 5 out of 5 by smooth trans with prolong Use this treatment in our Harley Transmissions smooths them right out...!!! March 16, 2015
Rated 5 out of 5 by Excellent product, I use it in all my cars! A very good friend recommended prolong Trans treatment who has a transmission rebuild shop. He rebuilds all types of Trans with a specialty In European transmissions. All his transmissions come with warranties Primarily because he tops all his rebuilds with prolong transmission treatment. He also recommended it on my sons Jeep Grand Cherokee which was shifting roughly and it cured all the issues in under 200 miles! 145,000 miles and still shifting like a champ! November 15, 2014
