I was driving along the highway and out of nowhere RPMs started fluctuating and I starting slowing down. It then jerked forward for a few seconds seeming okay until it cut out again and I was just rolling with the engine still revving. I can change gears just fine and no grinding noise but once it's heated up and I gas it, it'll make a noise like the belt is burning but it's coming from the transmission area. All the fuses, fluid, vacuum hoses, seals and wires look fine. No battery or alternator issues and hasn't misfired. No leaks and filters all look good.

Hi,

If it is happening when hot only, it sounds like it is a line pressure related issue. Have you ever had the transmission flushed to clean out the transmission cooler?

If there was no evidence of an issue prior, this is what I suggest. Take a look through the attachment below. It explains how to test the cooler flow. It will be a little messy, but it will help determine if the cooler is plugging or if there is a different issue.

Let me know if this helps or if you have other questions.

Take care,

Joe
