I've got a 4 year warranty with ASWN (All State Warranty Network) on my Fairlane. And recently the Auto Tranny does not fell happy about shifting from P to R (a big bang can be heard coupled with something like a driveline twist), while other gears are fine (though a bit slow in changing gears). I'm currently planning to make a claim from them, but I'm not quite sure what I should do when dealing with those people (you know they're businessmen while I'm not). Is there anybody who have got some previous exprienece can share? I really need some advice on this issue. All help is appreciated.
