HEAR IT FROM OUR CUSTOMERS

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.

I’m impressed.

My daughter's 01 taurus wouldn't downshift from overdrive to 3rd going uphill. Did a flush and added 1/2 a bottle of Lucas Transmission Fix and the problem has never returned. This was approximately 6 months ago. I'm impressed.

Got better real quick after use.

I am a 12 year long truck and large school bus driver. They recently assigned me an 18 year old International Bluebird diesel bus with inline 6 cyl and automatic tranny. I think its an Allison 5 speed type. The bus has nearly 300K kilometres (about 180K miles) of urban and highway driving. Shifts were very rough at times with a loud woomph changing gears at times. Very noticeable and no doubt tough on the Universal joints etc drivetrain wise. So I grabbed a 24 ounce narrow tip squeeze bottle [Lucas Transmission Fix] and pushed the full amount. Shifts are not like a brand new bus but noticeably quieter and less shocking. Got better real quick after use.

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 have been using Lucas Transmission Fix as a preventative maintenance for years…

I have been using Lucas Transmission Fix in my 2003 Escalade just as a preventative maintenance for years and have not had any transmission problems so far with over 230,000 miles on the original transmission, and it runs cool. Thanks Lucas.
