I am not associated with sprintex at all. I am a pilot for United Airlines. Sprintex is not perfect. As for the transmission problems. I really don't have any. If I go max blast it does shift by itself. Sometimes if I am just driving I do force the shift. I am trying to converse gas and I want the shift points where I want them. It's a personality defect.

Gas mileage has settled down to 14-15 mpg combined. If I gun it a lot it goes down to 12.

The only negative is that it does not like the cold. If temp is below freezing and I don't let it warm up for a couple I might have a misfire. If I let it warm up, there is no problem.

Why did I go with sprintex? Saved over a grand on the other systems and low end torque. It also looks good.
