First of all Thank You for the reply. This is the first time I sent a manufacture a message and actually got a reply!! I went ahead and purchased 1 quart of Trans Fix to replace a quart of ATF(Mercon). Did the fluid change up in Connecticut in the Norwalk area, and by the time I made it home back to Jersey(about 60 miles) I could feel a big difference in the shifts. This morning heading to work I was amazed at the way my old truck was shifting. All I have to say is WoW! This is the first time I used an additive in the manual trans, and now I'm hooked!
