HEAR IT FROM OUR CUSTOMERS

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.

It shifts amazingly no slips or leaks.

I had a 2001 suburban that would flare between 2nd and 3rd and slipped really bad when warm. I changed fluid and added 1.5 bottles of Lucas [Transmission Fix] and now even leadfooting it it shifts amazingly no slips or leaks, thanks Lucas!!

The transmission shifted so smooth and was like new again!!

Lucas Oil Products are AMAZING!! I used the Transmission Fix in my 1990 ford ranger which had 265,000 miles on it, and after adding the Transmission Fix with new fluid and filter, transmission shifted so smooth and was like new again!! AWESOME PRODUCTS!!! Tested, proven, and effective!!

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.
