IF YOU DON'T WANT TO GET TAKEN ADVANTAGE OF ASK THESE:

#1: Ask the shop if they charge to diagnose vehicles, we don't. If so, how much and what does that involve?   

#2:  Do not call a shop and tell them you need a major transmission overhaul; if you diagnose your vehicle chances are they won't contradict you.  Tell them you need your vehicle diagnosed.

#3: Demand an "out the door" price, if they can't give you that there is a reason why.  If they are in the business they know what each transmission takes to do an overhaul and should be able to provide a guaranteed quote.

#4: MAKE SURE THE PERSON WHO BUILDS YOUR TRANSMISSION IS THE PERSON THAT INSTALLS YOUR TRANSMISSION TO AVOID THE "BLAME GAME" BEING PLAYED WITH YOUR WARRANTY
