Whats up everyone?

I just found out about this site and I have heard its very informative and helpfull. My question is- I have a 2001 Ram 1500 5.2L with 65,500 miles. I have been noticing that when I am driving between 60 and 70mph my rpms are reving up over 2000 and then letting off. It has been happening maybe 2-4 times per min. I am not excelerating any harder when this happens. Just keeping the pedal steady. Has anyone had or heard of this problem before or might know what it could be?

Thanks

 

Welcome to the site.

 

Sounds like the torque converter is unlocking when it shouldn't.
Check your tranny fluid. If it's not the fluid level have a mechanic look at it.
Whatever it is, it'll probably get worse if you don't.
