HELP needed with GMC transmission problem

Jul 06, 2008 3 Replies

My 2000 Sierra just started having a problem with a server jump from



1st to 2nd gear. When starting from a dead stop and my automatic goes from 1st to 2nd on take-off, I get a very bad jumping jerk of the truck. All other gears are good.

To get around the problem I began starting off in 2nd gear from a dead stop.



Any help is appreciated. Terry in Texas

Have you tried adding a small amount of brake fluid to the transmission fluid? It will smooth out rough automatic shifting.
