HEAR IT FROM OUR CUSTOMERS

The transmission has been working perfect for the last 25,000 miles!!!!!!

My 1999 Subaru Legacy Outback started to not go into drive or there was along delay. I heard that this is a problem that many people see with these older Subarus. So I decided to try your Transmission Fix along with changing the transmission fluid with Lucas Semi-Synthetic Transmission Fluid. Well right after the change in fluids the transmission worked better then before and went right into drive. It did however started to have a delay again after a few thousand miles so I did the same fluid change again and the transmission has been working perfect for the last 25,000 miles!!!!!!

Thanks for what you do!

I purchased a bottle of Lucas Oil Transmission Fix yesterday and put it in my 1981 Corvette collector car I recently purchased at a Mecum auction in Fort Worth. The car has the TH350C automatic with the locking torque converter. The car is all original right down to the last nut and bolt and had spent its entire life indoors when not being driven in perfect weather. I’ve driven it about 500 miles since I purchased it and noticed recently that when in park and idling the transmission whined a bit, kind of like a needle bearing starting to show some wear. I started researching your product because of the Lucas reputation and bought the Transmission Fix product and added it yesterday afternoon and immediately the whine went away but as I drove it I realized that was just the tip of the iceberg. It shifts so smoothly that it almost feels like it has a CVT transmission in it. When the locking torque converter kicks in that is a lot smoother as well. When I shifted it from park to either reverse or drive the first few times I thought the shift linkage had broken it moved so smoothly. The motor seems to not be under near as much stress idling in park or going down the road and a lot of just overall noise is gone from the car. It was one of those kind of deals where I didn’t realize the noise was there until it was gone. Thanks for what you do!

Just amazed at how well your products help.

Just amazed at how well your products help. I have a 2011 F150 and just hit 700,000 miles on it, though I use both your oil stabilizer and transmission additive. I have had engine work done but my transmission is still all original and still going strong at 700,000 miles. Due to my diligence of changing my transmission fluid and filter every 30,000 or 40,000 miles, as well as an oil change every 8,000 or 10,000 miles, just depends on wether the miles are highway or city. Thanks again for a great product line.

After changing the fluid and the filter and adding Lucas, my transmission was renewed

I have a 2007 F150. The transmission was shifting hard. I was told the differential needed work. I had the driveshaft replaced which helped. A mechanic recommended Lucas [Transmission Fix]. He thought the transmission had issues. He didn’t recommend changing the fluid or the filter. After changing the fluid and the filter and adding Lucas, my transmission was renewed. Lucas is amazing. -

I bought the Lucas Transmission Fix fluid and all of my problems went away!!!

I just want to say thank you!! I had two or three codes from my transmission relating to solenoids and wiring etc. I was having very rough shifting and slippage. I didn’t want to spend hundreds replacing anything so I bought the Lucas Transmission Fix fluid and all of my problems went away!!! Codes cleared, shifting is smooth, and I’m happy. I didn’t know it could be this easy. I definitely recommend using this before considering repairs.
