GEN 1 Transmission issue

[chrismo]

I have a 2011 with 90k miles. The transmission slipped trying to shift from 5th to 6th. It happened twice in the span of maybe 5mins. The rest of trip it was shifting smoothly. Should I be worried?

Check for latent codes... Could be an intermittent misfire which can mimic a trans slip... Had a coil start to go bad on me years ago on an f150. Would only misfire periodically when the trans locked up at low rpms. Had to have a dealer do a stress test on the coils to determine which coil was bad. Good luck.

Will do. Thank you for the reply.

Check the transmission fluid level as well.

Turns out the speed sensor just needed to be replaced. Thanks though!
