2004 Suburban-Transmission-Erratic Shifts
4-wheel drive, 80k miles
Had transmission serviced at 75k. They said that fluid/pan looked real clean.
A lot of mountain driving, yes we have the forest fire going about 7 miles from our place.
Noticed that when going up grade, in cruise control, between 40-60mph, it starts downshifting at weird times. Once on Friday, it downshifted, immediately upshifted, and then downshifted again.
Yesterday, a coupe of times I was cruising up to stoplights with my foot off of the pedal and the light would change while I was still rolling. If I stepped on the accelerator, there would be a lag before transmission picked up. One other time it seemed to be confused and didn't know what to do.
Any ideas?
Thanks
