tranny

My tranny is now slipping I think? while traveling down the highway every 10 seconds the car revs about 200rpm and then everything is fine. what to do.......

Got a/c on? Or anything but vent or floor? If so, it's the converter unlocking and locking with the a/c clutch.

Why would that have something to do with the tranny

 

[Ian Macoomb]

Because when the compressor cycles on and off, the torque converter locks and unlocks. On some cars it does it every ten seconds and the rpm's go up and down.

You can get a tuner from NESHO to correct that and do a bunch of other stuff. It would save some wear and tear on the torque converter.

Typically the a/c compressor will only cycle that fast if the refrigerant level is low - that would be something to check.
