Transmission and loss of power on cruise control?
I went on a trip this weekend and experienced some strange transmission issues. My wife was driving for about 2 hours on cruise control at 70mph.
She needed to speed up a little and the engine revved up but there was no transfer of power. I had her pull over after I realized what was going on.
It was like the transmission was in neutral. I think the 4x4 service light came on too.
After putting the vehicle in park, we tried drive again and nothing.
I decided to shift it in 4wd low and back. I heard a thump and later we were back in business.
On the way back from the trip it did it again but this time she hit cancel on the cruise control and power was transferred as normal.
I will pull the diagnostics tomorrow. I sure hate to have to replace a transmission after having this truck for 3 months. 2005, 5.7L, QDII, 70k miles
Any input would be appreciated.
