looking for first hand accounts (NOT WHAT THE BOTTLE SAYS OR WHAT YOU READ ON THE INTERNET) Tell me your true experiences (negative and positive) with any TRANSMISSION additives. What problem was fixed and the name of the product you used?


Asked by May 14, 2014 at 09:06 AM about the 1994 Cadillac DeVille Base Sedan

Question type: Maintenance & Repair

there are so many products and opinions and claims on tranny additives- all the way from add Lucas to add a pint of type F - I want true accounts of what you used and how it worked for your tranny !

True account, I don't use additives in my transmissions, only the correct fluid that is recommended. If there is an issue or leak, I have it properly repaired.


I've gone to manufacturer's sites and of course they are merely trying to sell. I went to some edu sites and read actual chemists describe the contents - all the way from mineral oil to wax. Stay away from this stuff is what I'm walking away with.
