2006 chrysler 300 (code P0732)
 

Had a code of P0732. When driving down the highway, it will pop into neutral and when going in 2nd gear will slip. I don't know if there is a transmission sensor/relay that maybe bad causing the transmission not to perform correctly. Has 126,000 miles on engine. If anybody has idea, please let me know. Thanks

engine size or what type of trans u have

It has a 3.5L engine, not sure about the Aotmatic transmission.

How do you check the transmission fluid? I don't see a stick any where. I do see a small cap that stated for dealer use that seems where a fluid stick would go in.

I would suggest that U take it to a trans shop or dealer
