2019 3500 HO with Aisin that has erratic shifting

I have a 2019 3500 HO with Aisin that has erratic shifting. Under acceleration it will shift into neutral. , while in drive. All the gear shift indicators light up at this time. I can shift to neutral and back to drive and the transmission went back to working properly. I did have the trans fluid and filter changed. Does anyone known of a fix for this issue?

Did the shop use the special trans fluid or some generic stuff? If not, you WILL have issues. When I have my fluid changed, I go to the shop to make the appointment and tell them what tranny I have and what fluid it must have.

Check your Owner's Manual.

A few more details regarding current mileage and previous maintenance history would help. Did the shifting issue start AFTER the transmission service, or did it exist prior to servicing the transmission?

In any event….you have other issues going on if there’s illumination of all of the gear shift lights.

shift to neutral

Thanks for your response. The truck has 145000 miles on it. It was doing the shift to neutral one time before trans. service. It does not do it on a regular basis. The shift indicators only come after after the shift to neutral. No codes come up. I used ATF +4 transmission fluid.

I don't thank that is the right trans fluid. The 68rfe's use the ATF+4. The Aisin trans use a different fluid.

Thanks, for the replay. Do you know what the fluid type is for the Aisin?
