Car need transmission replaced - there is no warning on car that transmission is having major issues (ie no check engine light). My car shakes on turning this has been on going since I purchased the car in 2017. In late 2023 the car did not have as much pick up power like it used to and had a whining noise once you drive for a while (without the power it used to). There were no check engine light warning to date. On 1/12/24 I used auto zone engine diagnostic and following error codes came up - P17FO - CVT JUDDER P17F2 -JUDDER T/C inspection Diagnostic at AAMCO ON 3/25/24 show additional issues that don-??t show any warning signs eg check engine light PER AAMCO additional issues: Engine missing cylinder 3,4; and cylinder 1 is misfiring. Transmission juddering around 2nd gear, chain slipping under pressure-??transmission having internal mechanical failure. I am not sure if these issues are serious enough to show as check engine. If they should I don-??t know why my car check engine light is not on?

Check engine light appeared without warning and car would slow down and no longer accelerate on the highway. Took to the dealership and was told it needed a new transmission with only 64,000 miles of use.

The contact stated that the vehicle started to shake more violently while slowing down. The contact stopped the vehicle and felt resistance from the shift lever while attempting to shift the vehicle into park (P). The contact stated that the check engine warning light momentarily illuminated, but then turned off.
