Ken Gremillion uses Lucas Transmission Fix

I purchased a Hurricane Katrina damaged 2006 Toyota Tundra. This vehicle had been under water for about 4 weeks. The vehicle only had 6 miles on it when it flooded. It was on a dealer lot. I brought the truck to my mechanic who drained all fluids and filled with fresh oil. On the transmission, he left the drain plug out, started the engine to let the oil circulate and flushed the transmission with fresh oil for about 30 minutes. After about 4 months time, I had replaced the entire interior. I started driving the Tundra and the engine ran strong but when the transmission would shift into overdrive, the entire truck would vibrate and shudder and then the transmission would shift. I took my Tundra to a Texaco Lube Express and had the transmission fluid changed again. Their was still some water in the transmission but the service man told me he thought they had gotten it all out. I told him of the problem I was having when the transmission tried to shift into overdrive, and also sometimes between 3rd and 4th. He recommended I put a bottle of Lucas Transmission Fix. I was hesitant at first but agreed to try it. At first it made no difference in the shifting but by the next day I noticed that the truck would not shutter as much. The shifting continued to shift smoother until the noise quit completely. I drove my Tundra for about 1000 miles and had the transmission oil changed again, and added a bottle of Lucas Transmission Fix. It is unbelievable how smooth the transmission will shift. When I take off, I turn my radio off to listen to the transmission shifting between all gears and then into overdrive. Each gear shifts at the correct speed. I tell people it runs like a sewing machine. I know it saved me from rebuilding my transmission at a cost of about $3500.00 dollars. Thank you for developing a product that does what you say.
