GMC Canyon

[91142jim]

I have been towing my 08 I-5 automatic 4x4 GMC Canyon for 2 years. all info says it is a flat tow vehicle. It is easy to activate and deactivate towing procedure. "BUT" after towing for about the first 20 miles I have a burnt smell coming from under the vehicle. The oder does not start untill I put transmission back into drive. Also
when I put it back into drive it sounds like I am tearing the the gears out of the transmission then a loud clank. My dealer has been in contact with GM and they say it is normal. GM faxed my dealer 14 things not to do because they would not reemburse them. Has anyone had a simular experienc or have any helpful info.
My dealer has spent alot of time trying to help me and they extend my warrenty for 2 years or 100k miles.
Thanks for any help, JIM

Did you check your fluid levels in the transmission ? Did you sniff the fluid to see if it smells burned?

We have towed our '05 Colorado I-5 auto for about 6 years and 60K miles. I get the "Klunk" and the smell. My mechanic said the klunk is normal and I think the smell is just dirt that sticks to the exhaust system that burns off when you run the truck. I've een very pleased with the little truck!

A smell is quite common - road dirt/grime collecting on the underside as you tow, and it burns off when you run the engine. As long as the tranny fluid is clean and has no "toast" smell, I wouldn't worry about it.

The gear sync noise is awful but not unusual with that transmission. My previous Suzuki 4wd did it too.

We towed a 1999 Subaru then a 2008 Subaru. Both had the smell. The cause is covered above. I don't know about our Edge yet because I haven't towed it.
