From doctors, lawyers, tech support, contractors, tutors, auto and boat mechanics, appliance technicians, veterinarians, accountants, appraisers, psychologists, engineers, heavy machinery masters, dream interpreters, and more, we've got you covered, 24/7. My name is \*\*\*\*\* \*\*\*\*\* I will be able to assist you. I’m sorry that you’re having trouble with your vehicle. Don’t worry though, we’ll be able to figure this out. Thank you for taking the time to let us help you out with this problem and hopefully we can sort it out quickly. Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. It sounds like your transmission has a problem. Either with the torque converter or the transmission failed internally with the gearing or clutches. You'll have to check the line pressure on the transmission if the [engine](/topics-engine-gmc/) will stay running. If the transmission seized or the converter is seized then it won't start and you'll just have to remove the transmission. I would have the rear end inspected very carefully if you have a bunch of metal shavings in it also. My goal is to give you the best service possible and to help you. If you have any questions or concerns, please don’t hesitate to let me know. If I’m not online at the time, I will respond ASAP when I get back.
