Mike Glenn Recommends Lucas Transmission Fix After the Product afforded Mike another 175K Miles on his Chevy Venture

I have been meaning to write this note for a few years, but never got around to it. I have a 1998 Chevy Venture with over 373,00 miles. At the 200,000 mile mark the transmission stopped changing gears. A mechanic recommended Lucas as a last resort before a rebuild. It has given my van 175,000 more miles. I have recommended it to a number of friends who have been helped by its use. Thanks for a great product. I also use
the oil in the engine. Mike Glenn
