I dont recommend ATS at all... trans does not work right, nor ever will, until they change the way they operate 1st to 2nd shifts and does not compare to suncoast in any way,shape,form, or color. I have had PLENTY of customers use there trans' and had all unhappy when they road in a suncoast truck. MY opinion is not just mine, but also based off of x employees. Not tryin to start any problems, wish it wasnt that way as they are technically local and use to do warranty work for them, not anymore, never again. I have heard nothing but good about gorend, but will recomend suncoast every time. If you need help with any decisions or install or purchasing, will be glad to help. My engine builder (Geddes Auto Machine) is in the springs and am regularly sending things back and forth. we will be glad to help.
