Wayne Derksen uses Lucas Transmission Fix in 1978 Monte Carlo

After my 1978 Monte sat for about 2 years I decided to reactivate it.Well,I found out that Turbo 350 trannys develope problems with the front pump seal if left to sit to long.I was losing 4 litres of trans fluid over night.I installed a bottle of your transmission seal conditioner about a month ago.With no exaggeration,the car has not lost a drop of fluid since.In this day and age when you cannot trust anyone or anything to do the right thing,it is refreshing to find a product that does exactly what you claimed it would do.Thank you,I will be a loyal customer for life.
