David R. Juhl uses Lucas Transmission Fix in '02 Dodge 4X4 Diesel

I had what appeared to be a real bad weekend until LUCAS saved my butt.

I purchased an El Dorado National bus that was located in Philly,PA. We hitched up a friends 30' goose neck to my '02 Dodge 4X4 Diesel and went to get it. What a load ,28,000 LBS.and 400 miles home!

After going up a 10 mile long grade 6% to Turkey Hill PA. we decided to let the truck have little rest. After stopping I let her idle down for 10 min. before shutting down. We had a good dinner and set out for th rest o the trip home. Oh No, what happened to my tranny,won,t shift out of 2nd and the lock up converter is going nuts,lock up and unlock and won't quit.Now what do we do ? 200 miles from home ,tranny takes a dump and we have 21 K behind us ! I nursed the sick Dodge into Bath,N.Y. and found an Advance Auto Parts store open. We checked the tranny fluid again it was only down a pint. Now I decide to try some Lucas Transmission Leak and Conditioner. One pint and back on the road , TRULY a blessing from the almighty KING LUCAS himself !We made it home ok and the truck has never shifted better.

With a heart felt thanks you can count on me as a faithful new customer and a profit spreading the good word of your products.

Sincerly , David R. Juhl

P.S. I have been a Heavy Truck Mechanic & Truck Driver for over 30 years.
