We understand the vast area of automotive repair and the technological terms that come with that so we are trying to provide a window into that terminology that will help you navigate your way through this process. We don't care if you're going to the grocery store and what you were going to buy! LOL  What we do care about is needing the information that is listed below:

• Year/Make/Model= the year model, brand of the vehicle(GMC, Chevy, Dodge, etc) and the model it is; VIN=17 digit number located on your driver door or base of windshield on the drivers side
• Size of your truck=1/2, 3/4, 1-ton=1500, 2500, 3500
• # of Lug nuts on your wheels=6 lugs is 1/2 ton vehicle; 8 lugs=3/4-1ton
• 2WD or 4WD?  Do you have a shifter on the floor or an electronic switch on the dash?
• What do you use the vehicle for? (i.e. hauling cattle/camper/boat/atv, an everyday driver), hot shot drivers)

• Slipping = vehicle trying to take a gear and the RPMs go sky high and stay that way or eventually shift
• Delay in engagement = when you put the shifter in D/R and give it gas and there is no exceleration; 
• Hard shift = you can feel it more so than before
• Long shift = seems to take longer to change gears 
• Torque Converter Shudder = feeling of driving over a cattle guard or the rumble strips that are on the side of the highways
