Testimonial for Lucas transmission fix and oil stabilizer: The saga of Frankenvan

Frankenvan is a 1992 dodge caravan, 3.3L V6. We bought it in 1998 with 74,000 miles on it. January of 2002 with 113,000 miles the tranny went, I had nothing but first gear for 13 miles on the way to work. I cracked the pan, took out a quart, and put in a bottle of Lucas transmission fix. Within a mile I had my tranny back. My buddy a master mechanic, told me I had a couple of months tops, today Lucas goes into all his own cars, and mine.

Frank just turned 241,700 and is about ready for retirement, he cant be killed, there is just too much else wrong. I have never had the engine or trans rebuilt, I have never even changed the trans filter! The trans had a slow leak after I cracked the pan and that's how I change the fluid 50/50 Lucas transmission fix and regular trans fluid every two months or so.

I began putting the Lucas oil stabilizer into the engine as soon as I realized the trans would be fine. Two years ago the oil pressure went away, my buddy told me I needed to rebuild the oil pump, I just ran two bottles of Lucas oil stabilizer per oil change, that did the trick, when the pressure starts to drop after about 4,500 miles its time to change the oil.  

I don't know if you hear of this kind of success 18 times a day or once a year, I will keep Frank around for maybe 2 weeks yet before I get rid of it. If this is something you want to tear down and access it will be available to you first, after all it wouldn't be here today without your products.

Thanks from a lifelong customer,
Chad Soleski
