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.

Lucas Transmission Fix Works Miracle on Ford Contour

My old 1997 Ford Contour with 144,000 miles starting slipping while I was driving on the Interstate. Car would slow down while engine revved higher/ Nothing I did changed the problem, shifting into 3rd ect. I was told I needed a new Transmission. Did some research on-line and found a lot of testimonials. I put one half bottles in transmission and no more slip! A true miracle and saved me 2800.00! Thank you Team Lucas!!

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!!!!!!
