Wife tells me that her 2008 GMC Yukon XL with 120k miles shudders when in reverse. Of course, it only happened a couple of times before she told me about it.
Just finished my checks. Car does shudder when the transmission is in reverse. Shudder goes away or is substantially reduced in drive. I only tested it for 20 feet.
Check transmission fluid while cold. Dipstick shows full with no burning or blackened cherry juice. Checked the transmission fuse and it is fine. Used a flashlight to look around the front drive train and do not see anything that appears broken.
What am I missing? What should I be checking? I think it is the transmission.
I hope to drop it off in the morning at a local shop as my transmission knowledge is limited.
What should I expect to hear?
Thanks.
