Evan Myklebust uses Lucas Transmission Fix in 1994 Ford Ranger

I bought a used Ford Ranger for a commuter a little while ago with a slow transmission leak. The previous owner would add fluid when the trans started making noises. ( I found this out a few months after I had been driving it ) I did this a few times and had run across Lucas stop-slip so I thought I would give it a try even though I had a manual trans. I put a bottle of stop-slip and two bottles of gear oil ( yes I know that it is susposed to have ATF ) and within 50 miles all the noises from the transmission have completely disappeared. I drive 60 miles a day for work and have put 10,000 miles on the truck since I put your product in and I'm definitley a customer for life.

Thank you, thank you, thank you!
