[AT] OT - Pickup Transmission Question

[charlie hill]

Thomas,

I had heard stories about our local AAMCO.  I needed some transmission work 
done and none of the local jacklegs suited me either so I called AAMCO.  I 
told the guy what the transmission was doing (GM TH350) and that I thought 
it needed a complete rebuild.  I asked him about what it would cost and told 
him I wouldn't hold him to the  exact amount.  He wouldn't tell me.
Said he'd have to pull it down first and he proceeded to tell me about their 
pull down charge, etc. So I said, OK if you tear it down and have to replace 
everything in it from one end to the other, except the case, about what will 
it cost me.  He said he didn't know and he'd have to pull it down first.  I 
said, yep just like I heard, you are a crook and I hung up.  Every thing 
else I've ever heard about them tells me I was right.

I think the local store is under new ownership now and maybe they are better 
but years ago 60 Minutes did a program on AMMCO practices nationwide.   They 
were the same as what the local shop was doing.

Charlie
