Lucas Transmission Fix is the real deal!

Lucas Transmission Fix is the real deal! My transmission delayed shifting out of 1st gear sometimes wouldn’t shift at all. 1994 Dodge 3500 w/ 5.9 Diesel. Three different transmission shops said the transmission needed to be rebuilt. I changed the fluid and filter and added Lucas Transmission Fix and crossed my fingers. After a couple days it started shifting again. That was 4 yrs. ago and still shifts like a new truck.

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 Smooth As Silk

I have a '94 Ford F150, hard shift between 2nd and 3rd. Added 1 bottle of Lucas Transmission Fix, started manual shifting between 2nd and 3rd for about 3 weeks and then went back to pulling out in drive hoping for the best. It is working smooth as silk! Thanks Lucas for a fine product.

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.

This product delivers as claimed! I just saved $1,300.00!

I have a 1987 Volvo 240GL with just over 270,000 miles on it that gets very little road time. When I got it five years ago the transmission was leaking. I replaced the cooler line fittings only to discover the trans was leaking from the main seal where the bellhousing attaches to the gearbox. To replace this is basically a full rebuild. I decided to give Lucas Trans Fix a try. Well after less that 50 miles of driving the leak stopped! This product delivers as claimed! I just saved $1,300.00!
