I have a 2008 Silverado Crewcab that is having transmission problems. The truck started making a high pitched whinnning sound when starting from a stop sign and it hesitates and grabs for second, sometimes clunking into second. The truck is serviced regularly at the dealership and have had multiple problems with the AFM but they have done nothing to fix my transmission. ANy ideas what it could be?

 

If I could would like to get some more information on your issue if I could. Thank you for your time.
