Any good transmission additives out there?

Recommended Posts

I wanted to get you guys' opinion/recommendation on transmission fluid additives? Are there any good ones out there?


I am generally not an additive kind of guy as I have seen all too many times the horrific issues "stop leak in a bottle" type additives cause. I have heard, though, when it comes to transmissions that some non-stop leak type additives can actually help free up valves and such in an old transmission. Some of the names I have heard good things about specifically are Trans-X and SeaFoam Trans. additive.


I really have a very limited experience with automatic transmission and to be honest don't understand them that well, I was hoping some of you transmission re-builders/gurus could help me out on this one.


Is there any that you would wholeheartedly recommend or am I better off not adding anything at all?


Thanks in advance,

We were using Seafoam for trans for awhile with hit or miss results. Lately, we started using BG's ATC Plus with really impressive results. One of our mechanics thought he was going to need a trans for his 98 Durango. Used the BG product and no issues. It's cured. We have also had really great results with their MOA engine additive. We don't do a lot of additives here either - but these two are worth their weight in gold.

I am not a big believer in additives to solve problems. We do promote Preventive Maintenance, and we use BG products. BG also has a Lifetime Protection Plan if you start the service before 75,000 miles. So they stand behind their products.


I also tell my customers that are keeping their cars for a long time to service all the fluids BEFORE they turn color. For example, when the tranny fluid is burnt and brown, it's too late.


Like I always say, "The time to start thinking about taking care of yourself is not when your in an ambulance after having a heart attack"

      Most shop owners would agree that the independent auto repair industry has been too cheap for too long regarding its pricing and labor rates. However, can we keep raising our labor rates and prices until we achieve the profit we desire and need? Is it that simple?
      The first step in achieving your required gross and net profit is understanding your numbers and establishing the correct labor and part margins. The next step is to find your business's inefficiencies that impact high production levels.
      Here are a few things to consider. First, do you have the workflow processes in place that is conducive to high production? What about your shop layout? Do you have all the right tools and equipment? Do you have a continuous training program in place? Are technicians waiting to use a particular scanner or waiting to access information from the shop's workstation computer?
      And lastly, are all the estimates written correctly? Is the labor correct for each job? Are you allowing extra time for rust, older vehicles, labor jobs with no parts included, and the fact that many published labor times are wrong? Let's not forget that perhaps the most significant labor loss is not charging enough labor time for testing, electrical work, and other complicated repairs.  
      Once you have determined the correct labor rate and pricing, review your entire operation. Then, tighten up on all those labor leaks and inefficiencies. Improving production and paying close attention to the labor on each job will add much-needed dollars to your bottom line.

      The transformation was not changing the world but changing who I was and how I looked at things Service advisors should have a human connection with each customer Look around at the processes that make the magic happen The questions are the most powerful part- “What would you do if I wasn’t here” Don’t be the answer man, find the solution- teach the change of thinking so your team can come up with the solution and own it.  Tracking how many customers to know how much you have grown  The number 1 job of a leader is to replace yourself with someone better Fix the owner. Fix the shop Stop stopping -  the moment you stop, the current will push you back. It’s easier to keep going than stop and restart.  Make more time to visit shops and see how they're doing  Leadership in associations- it's not just who you are in that position, but how did the person before you influence you? and how will you influence the next person? Don't break that progress, keep that progress going

      When I was in business, each year for 41 years, we experienced a slow down in February. The reasons are many, but by the second week of March, things went back to normal.   
      However, from what I am hearing from some shop owners, they are concerned. They point to riding this wave of business since coming out of COVID, and fear that the wave may become a trickle. 
      What is your opinion?  Good times are still here? Should we be concerned?
