Greg Hutchings uses Lucas Transmission Fix for 1995 Dodge Intrepid

Charlott Lucas:

I just wanted to tell you that your product is the very best on the market today, hands down.

I have a 1995 Dodge Intrepid and the transmission has been acting up in it for years. Not shifting, hanging up in third and so on.

I saw a bottle of your transmission fluid and thought I would try it. I did, and I have never had a problem out of the trans again. It shifts perfect now, so thank you for a fine product, its the best, nothing else even comes close!!
